Within the Eurasian customs union, do not use machines without the appropriate EAC marking. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 19 Description 3.1 Area of application Use in hazardous areas Explosion-proof electrical machines correspond to standards of the IEC/EN 60034 and IEC/EN 60079 series. Only operate the machine in hazardous areas, strictly complying with the specifications of the responsible supervisory authority. The relevant supervisory authority is responsible for determining the hazard level of each area and classifying the zones. The type of protection as well as special regulations are stamped on the rating plate or in the test certificate. If the certificate number is supplemented by an X, to safely operate the machine observe the special notes in the operating instructions or if available in the EC or EU typeexamination certificate or in the IECEx Certificate of Conformity. Operation with a converter must be certified. It is essential that you observe the separate manufacturer's information and instructions. Explosion hazard from hybrid mixtures Hybrid mixtures are mixtures of flammable dusts with explosive gas/air atmospheres which can together create a dangerous explosive atmosphere if they occur at the same time. Changes can arise in the safety characteristics here, such as a change in the zonal classification, increase in the explosion pressure, reduction in the minimum ignition energy and a reduction in the maximum temperatures to be observed. An explosion can result. This can result in death, serious injury or material damage. For this reason, the relative characteristics must be considered both for gas (zones 0, 1 and 2) and for dust (zones 20, 21 and 22) where hybrid mixtures arise. It is necessary for a competent assessor to determine in the individual case whether the parameters determining ignition are unfavorably affected in a particular hybrid mixture. Motors with dual plates for G ("Gas") and D ("Dust") may only be used where these two occur after prior examination of the properties of the hybrid mixtures by the user.

The surface cooling varies depending on the version. 3.3.2.1 Machines with a fan Self-ventilation (standard): Cooling method IC 411 according to EN / IEC 60034-6 Located at the ND end of the stator housing is an air intake cowl that guides the external air on its way to the motor. The external air is drawn in through openings in the air intake cowl and flows axially across the outer cooling ribs of the motor frame. The fan wheel for the external flow of cooling air is attached to the machine shaft. The fan wheels are bidirectional. Check the cooling effect below rated speed in the case of frequent switching or braking - or if the speed is controlled continually below the rated speed. Forced ventilation (optional): Type of cooling IC 416 in accordance with EN / IEC 60034-6 Cooling that does not depend on the speed is achieved by means of a unit that is independent of the motor operating state (forced ventilation). This unit is closed to the outside by a fan cover. It has its own main drive with fan impeller which creates the cooling air flow required for cooling the motor. 3.3.3 Bearings In order to support the machine shaft and maintain its position in the non-moving part of the machine, only 2 rolling bearings are used. One rolling bearing performs the function of a location bearing that transfers axial and radial forces from the rotating machine shaft to the non-moving part of the machine. The second rolling bearing is implemented as floating and support bearing in order to allow thermal expansion inside the machine and transfer radial forces. The nominal (calculated) useful life of the bearings according to ISO 281 is at least 20,000 hours with utilization of the permissible radial/axial forces. However, the achievable useful life of the bearings can be significantly longer in the case of lower forces (e.g. operation with self-aligning couplings). Rolling bearings with permanent lubrication are maintenance-free. The machine is equipped with grease-lubricated rolling bearings. In the standard version, the bearings of machines up to shaft height 250 are permanently lubricated. The bearings of machines from shaft height 280 and above are equipped with a relubrication system. 1MB155 / 1MB555 SH 71 ... 355 24 Operating Instructions, 12/2018, A5E41926185A Description 3.3 Design 3.3.4 Balancing As standard, the motor is balanced dynamically with a half feather key (code "H").

If any transport locks are in place, remove them before commissioning. Store the transport locks or disable them. Use the transport locks when transporting the motors again or reactivate the transport locks. The machines are packed in different ways depending on how they are transported and their size. If not otherwise contractually agreed, the packaging corresponds to the packing guidelines according to ISPM (International Standards for Phytosanitary Measures). Comply with the images shown on the packaging. Their meaning is as follows: Up Fragile goods Protect against moisture Protect against heat Center of gravity Hand hooks forbidden Attach here 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 33 Preparations for use 4.5 Transport and storage 4.5.1 Storage Storing outdoors NOTICE Damage to the motor Damage can occur if incorrectly stored. Take all precautions to protect the motor under extreme climatic conditions, e.g. salt-laden and/or dusty, moist/humid atmospheres. Choose a dry storage location which is safe from flooding and free from vibration. Repair any damage to the packaging before putting the equipment into storage if this is necessary to ensure proper storage conditions. In order to ensure protection against ground moisture, locate machines, equipment and crates on pallets, wooden beams or foundations. Prevent equipment from sinking into the ground. Do not impede air circulation under the stored items. Covers or tarpaulins used to protect the equipment against the weather must not come into contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air can circulate freely around the equipment. Storing indoors The storage rooms must provide protection against extreme weather conditions. They must be dry, free from dust, frost and vibration and well ventilated. Bare metal surfaces For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be coated with an anti-corrosion agent which will last for a limited amount of time (<6 months). Apply suitable anti-corrosion measures for longer storage times. The materials used are specially designed for the temperature range required by the customer. The relevant temperature limits are specified on the rating plate. WARNING Risk of explosion due to damaged sealing materials Storing the machine at temperatures that do not fall within the specified limits can damage the material of the seals and cause them to fail. As a result, a potentially explosive gaseous atmosphere can enter the machine and be ignited during commissioning. Explosions can occur. This can result in death, serious injury or material damage. * Do not store the machine in conditions that lie outside the specified temperature limits. Storage temperature Permissible temperature range: -20 C to +50 C 1MB155 / 1MB555 SH 71 ... 355 34 Operating Instructions, 12/2018, A5E41926185A Preparations for use 4.5 Transport and storage Maximum permissible air humidity: 60% For machines that have a special design regarding the ambient temperature in the operating state or the installation altitude, other conditions could apply regarding the storage temperature. In this case, refer to the machine rating plate for data on the ambient temperature and installation altitude. Storage time Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce the useful life of the bearing grease (aging). Open bearings For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12 months. Replace the grease if it is identified that the grease has lost its lubricating properties or is polluted. The consistency of the grease will change if condensation is allowed to enter. Closed bearings For closed bearings, replace the DE and NDE bearings after a storage time of 48 months. NOTICE Storage The motor can be damaged if you use it or store it unprotected outdoors. * Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a superstructure or additional cover, for example. * If required, contact the service center, or technically coordinate outdoors use. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 35 Preparations for use 4.5 Transport and storage 4.5.2 Securing the rotor Depending on the version, the machine is fitted with a rotor shipping brace. This protects the bearings against damage due to shock and vibration during transport or storage. NOTICE Motor damage due to vibrations Not using the rotor shipping brace can cause damage to the machine if it is jolted during transport or storage. Material damage can result. * If the machine is fitted with a rotor shipping brace, this should always be used when transporting the machine. The rotor shipping brace must be attached during the transport. * Protect the motor against strong radial shocks and vibration when storing, as the rotor shipping brace cannot completely absorb these forces. * Do not remove the rotor shipping brace until you are ready to push on the output element. * If the customer already has mounted parts, such as a coupling or belt pulley, the bearings can be damaged during transport. In this case, make sure that the customer uses a rotor shipping brace. * For machines with a vertical type of construction: - Do not remove the rotor shipping brace until the machine is in a vertical position. - If a machine has to be transported in a horizontal position, the rotor must be fixed in position before the machine is turned onto its side. Vertical machines can be supplied in the horizontal position from the manufacturing plant. 1MB155 / 1MB555 SH 71 ... 355 36 Operating Instructions, 12/2018, A5E41926185A Preparations for use 4.5 Transport and storage Alternative rotor bracing If you transport the machine after the output element has been pulled on, then you must axially fix the rotor in another way.

It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 51) 4.5.3.2 Lubricating the rolling bearings If you correctly store the machine for a longer period of time, it can be assumed that within a period of two years, the grease in the bearings will not deteriorate. For motors with thermal class 155, for normal ambient temperatures, use a lithium-soap rolling bearing grease with a melting point of at least 180 C. For machines with thermal class 180, and for certain special machines, use the special grease specified on the machine lubricant plate. 4.5.3.3 Regreasing rolling bearings after storage periods of up to two years For machines with regreasing systems, briefly lubricate both bearings after commissioning with the machine running as a precautionary measure. Grease type, grease quantity and relubrication intervals for the regreasing system are stamped on the rating plate attached to the machine. 4.5.3.4 Releasing the rotor shipping brace before commissioning If one is being used, release the rotor shipping brace before commissioning. 1MB155 / 1MB555 SH 71 ... 355 38 Operating Instructions, 12/2018, A5E41926185A Preparations for use 4.6 Ensure adequate cooling 4.6 Ensure adequate cooling WARNING Overheating and failure of the motor Death, severe injury or material damage can occur if you do not carefully observe the following points. * Do not obstruct ventilation. * Prevent the air expelled by neighboring equipment from being immediately sucked in again. * For machines with a vertical type construction with air entry from above, prevent the ingress of foreign bodies and water in the air entry openings (standard IEC / EN 600790). * If the shaft extension is facing upwards, liquid must be prevented from entering by moving along the shaft. WARNING Damage caused by small parts falling in Material damage and injury can occur if the fan is destroyed and therefore the motor overheats. * For types of construction with the shaft extension facing downwards, prevent small parts from falling into the fan cover by providing suitable covers (standard IEC / EN 60079-0). * Ensure that the cooling air flow is not reduced as a result of covers and that the minimum air clearances are maintained. For machines with external fans, install an interlock circuit that prevents the main machine being switched on if the external fan is not operational.

Thermal machine protection by directly monitoring the winding temperature is permissible if this is certified and test data specified on the rating plate. PTC thermistors for direct temperature monitoring (sole protection) ensure explosion protection in conjunction with function tested tripping devices in accordance with local regulations. Direct temperature monitoring for line (DOL) operation: You can operate the machine without a circuit breaker. Evaluate the temperature sensors. Direct temperature monitoring for inverter operation: Evaluate the temperature sensors. If you have to perform a continuity test of the temperature sensors, do not apply a voltage >2.5 V. If no test data is specified on the rating plate, this means that the winding protection is only intended as an additional protection. For pole-changing machines, use a direct temperature monitoring sensor as stated on the rating plate, e.g. PTC thermistor, for each speed level in addition to the separate, mutually interlocked machine protection relays. 4.8 Interlock circuit for anti-condensation heating If the anti-condensation heating is operated while the machine is running, this can increase the temperatures inside the machine. Install an interlock circuit that switches off the anti-condensation heating once the main machine is switched on. Only switch on the anti-condensation heating after the machine has been switched off. See also Switching on with the anti-condensation heating active (Page 98) 4.9 Noise emission Prevention of hearing damage If the permissible sound pressure level is exceeded, hearing damage can occur when operating three-phase motors at their rated power. Observe the permissible sound pressure level in accordance with ISO 1680. The maximum permissible sound pressure level is 70 dB (A). 4.10 Voltage and frequency fluctuations during line operation Unless stated otherwise on the rating plate, the permissible voltage/frequency fluctuation is corresponds to range B in IEC / EN 60034-1. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 41 Preparations for use 4.11 Rotational speed limit values Material damage due to excessively high winding temperature rise Do not exceed the winding temperature tolerances. Inadmissibly high winding temperatures can damage the machine over the long term. Keep within the permissible tolerance for voltage and frequency. Every machine must be protected against an inadmissible temperature rise. Observe the following notes: Protect every machine according to IEC/EN 60079-14 using a current-dependent, delayed circuit breaker with phase failure protection according to IEC/EN 60947 or a similar device in all phases. Set the protective device to the rated current (value is stamped on the rating plate). Protect the windings in a delta connection in such a way that the tripping unit or relay is connected in series with the winding phases. When selecting and setting the tripping unit, define the rated value of the phase current. The phase current is 0.58 times the rated machine current. Any thermal machine protection via direct temperature monitoring to be used in addition to the machine circuit breaker is specified on the rating plate if required. 4.11 Rotational speed limit values Danger as a result of resonance within certain speed ranges At over-critical speeds, machines encounter resonance within certain speed ranges. Such vibrations can reach impermissibly high levels. This can result in death, serious injury or material damage. The controller must ensure that those speed ranges are blocked when the converter is in operation. Please note the data on the blocked speed ranges specified in the Electrical Data. The blocked speed ranges must be run through rapidly. Machine damage due to excessively high speeds Excessive rotational speed can lead to serious damage to the machine. This can result in death, serious injury or material damage. Avoid operation above the permissible speed by using the appropriate control function. Observe the speeds stamped on the rating plate and in the Electrical Data. 1MB155 / 1MB555 SH 71 ... 355 42 Operating Instructions, 12/2018, A5E41926185A Preparations for use 4.12 System-inherent frequencies 4.12 System-inherent frequencies Excessively high vibration levels and system resonances can damage the machine set. Configure and match the system consisting of the foundation and machine set in such a way that no system resonances can arise and result in the permissible vibration levels being exceeded. The vibration values according to DIN ISO 10816-3 must not be exceeded. 4.13 Electromagnetic compatibility Note If the torque levels are very unequal (e.g. when a reciprocating compressor is being driven), a non-sinusoidal machine current will be induced whose harmonics can have an impermissible effect on the supply system and cause impermissible interference emissions as a result. Note Converter * If operated with a frequency converter, the emitted interference varies in strength, depending on the design of the converter (type, interference suppression measures, manufacturer). * Avoid that the specified limit values stipulated for the drive system (consisting of the motor and converter) are exceeded. * You must observe the EMC information from the manufacturer of the converter. * The most effective method of shielding is to conductively connect a shielded machine supply cable to the metal terminal box of the machine (with a metal screw connection) over a large surface area. * On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages caused by the converter may occur on the sensor cable. When used in accordance with their intended purpose and operated on an electrical supply system with characteristics according to EN 50160, the enclosed machines comply with the requirements of the EC Directive concerning electromagnetic compatibility. Immunity to interference The machines fulfill the requirements of interference immunity in conformity with EN / IEC 61000-6-2. If machines with integrated sensors (e.g. PTC thermistors) are used, the operating company must ensure sufficient interference immunity by selecting a suitable sensor signal lead (possibly with shielding, connected in the same way as the machine feeder cable) and a suitable evaluation unit. When operating the machines from a converter at speeds higher than the rated speed, then the mechanical speed limits must be carefully observed (safe operating speed EN / IEC 60034-1). 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 43 Preparations for use 4.14 Converter operation 4.14 Converter operation 4.14.1 Parameterizing the converter If the design of the motor requires connection to a particular converter type, the rating plate will contain corresponding additional information. Correctly parameterize the converter. Parameterizing data can be taken from the machine rating plates. You can find parameter data here: - In the operating instructions for the converter. - In the SIZER engineering tool - In the SINAMICS Configuration Manuals. - For explosion-protected machines, also in the declaration of compliance with the order 2.1. Do not exceed the specified maximum speed limit nmax. You can either find this on the rating plate nmax or on the supplementary plate for converter operation as the highest speed. Check that the machine is cooled sufficiently for commissioning purposes. 4.14.2 Converter input voltage The insulation system of SIMOTICS machines always complies with the requirements of stress category C (IVIC C = high stress). If voltage peaks higher than those specified according to IVIC C can occur, then please contact your Siemens partner: For a line supply voltage (converter input voltage) up to max. 480 V, and when controlled from a SINAMICS G/SINAMICS S converter with uncontrolled/controlled infeed: Comply with the guidelines for configuring motor and converter. For line voltages (converter input voltages) higher than 480 V, motors, which are ordered for converter operation, have an appropriate insulation system. Operation with a converter from another manufacturer: Comply with the permissible voltage peaks according to IEC 60034-18-41 in accordance with stress category C, dependent on the particular line voltage (converter input voltage) and the motor insulation system. NOTICE Material damage caused by an excessively high supply voltage The insulation system will be damaged if the supply voltage is too high for the insulation system. This can completely destroy the machine. * Comply with the peak voltages as laid down in the guidelines above. 1MB155 / 1MB555 SH 71 ... 355 44 Operating Instructions, 12/2018, A5E41926185A Preparations for use 4.14 Converter operation See also Download Center (http://w3app.siemens.com/mcms/infocenter/content/en/Pages/order_form.aspx) 4.14.3 Reducing bearing currents when operated with a converter Taking the following actions will reduce the bearing currents: Ensure that the contacts are made over a large area. Solid copper cables are not suitable for high-frequency grounding because of the skin effect. Equipotential bonding conductors: Use equipotential bonding conductors: between motor and driven machine between motor and converter between the terminal box and the RF grounding point at the motor enclosure. Selecting and connecting the cable: As far as possible, use symmetrically arranged, shielded connection cables. The cable shielding, made up of as many strands as possible, must have good electrical conductivity. Braided shields made of copper or aluminum are very suitable. The shield is connected at both ends, at the motor and converter. To ensure good discharging of high-frequency currents, provide contacting over a large surface area: - as contact established through 360 at the converter - at the motor, for instance with EMC glands at the cable entries. If the cable shield is connected as described, then it ensures the specified equipotential bonding between the motor enclosure and converter. A separate RF equipotential bonding conductor is then not necessary. Concentric copper or aluminum shield Steel armor 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 45 Preparations for use 4.14 Converter operation If the cable shield is not connected due to special secondary conditions, or not adequately connected, then the specified equipotential bonding is not provided. In this particular case, use a separate RF equipotential bonding conductor: - Between the motor enclosure and protective ground rail of the converter. - Between motor enclosure and driven machine - Use braided flat copper straps or high-frequency cables with finely-stranded conductors for the separate RF equipotential bonding cable. - Ensure that the contacts are made over a large area. Measures to reduce bearing currents To specifically reduce bearing currents, you must consider the system as a whole, which comprises the motor, converter, and driven machine. The following measures support you when reducing bearing currents and help to avoid damage: In the overall system, set up a properly meshed grounding system with low impedance. Use the common-mode filter (damping cores) at the converter output. The Siemens sales representative is responsible for selection and dimensioning. Limit the rise in voltage by using output filters. Output filters dampen the harmonic content in the output voltage. The operating instructions for the converter are not part of this documentation. Refer to the configuration information for the converter. 4.14.4 Insulated bearings when operated with a converter If the machine is operated from a low-voltage converter, insulated bearings are fitted at the NDE and an insulated encoder with insulated bearings (option). Comply with the plates on the machine relating to bearing insulation and possible bridges. Driving machine Motor Insulated bearings Insulated tachometer fitting Coupling Figure 4-2 Schematic representation of a single drive 1MB155 / 1MB555 SH 71 ... 355 46 Operating Instructions, 12/2018, A5E41926185A Preparations for use 4.14 Converter operation NOTICE Bearing damage The bearing insulation must not be bridged. Bearing currents can damage bearings. * Do not bridge the bearing insulation for subsequent installation work, such as the installation of an automatic lubrication system or a non-insulated vibration sensor. * Please contact the service center if necessary. Tandem operation If you connect two motors in series in "tandem operation", install an insulated coupling between the motors. Driving machine Motor Coupling Figure 4-3 Insulated bearings Insulated tachometer fitting Insulated coupling Schematic representation of a tandem drive NOTICE Bearing damage Bearing currents can flow if the coupling between the motors of the tandem drive is not insulated. This can damage the DE bearings of both motors. * Use an insulated coupling to link the motors. 4.14.5 Tandem operation If you connect two motors in series in "tandem operation", locate a coupling between the motors; this coupling should satisfy the Directive 2014/34/EU or the regulations that apply in the country where the equipment is installed. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 47 Preparations for use 4.14 Converter operation 4.14.6 Speed limits for converter operation Observe the information on the rating plate regarding the speed limits for converter operation. 1MB155 / 1MB555 SH 71 ... 355 48 Operating Instructions, 12/2018, A5E41926185A 5 Assembly Observe the following when carrying out any work on the machine: Comply with the general safety instructions (Page 11) Comply with the applicable national and sector-specific regulations. When using the machine within the European Union, comply with the specifications laid down in EN 50110-1 regarding safe operation of electrical equipment. Loss of conformity with European directives In the delivery state, the machine corresponds to the requirements of the European directives. Unauthorized changes or modifications to the machine lead to the loss of conformity with European Directives and the loss of the associated warranty. Explosion hazard when making modifications to the machine Substantial modifications to the machine are not permitted - or may only be performed by the manufacturer. Otherwise an explosion can occur in an explosive atmosphere. This can result in death, serious injury or material damage. If necessary, please contact the service center. 5.1 Preparations for installation 5.1.1 Requirements for installation The following requirements must be satisfied prior to starting installation work: Staff have access to the operating and installation instructions. The machine is unpacked and ready for mounting at the installation location. Measure the insulation resistance of the winding before starting any installation work. If the insulation resistance lies below the specified value, take appropriate remedial measures. These remedial measures may necessitate the machine being removed again and transported. Note Note also the technical data on the rating plates on the motor enclosure. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 49 Assembly 5.1 Preparations for installation NOTICE Damage to the motor To avoid material damage, before commissioning, check whether the correct direction of rotation of the machine has been set on the customer side, e.g. by decoupling from the driven load. Damage to mounted parts and components as a result of high temperatures The motor components get very hot during operation. High temperatures can damage parts mounted by customers, such as cables manufactured out of materials that are not heat resistant. Temperature-sensitive parts must not come into contact with or be attached to components mounted on the machine. Only use heat-resistant mounting parts. The connecting cables and cable entries must be suitable for the particular application. 5.1.2 Insulation resistance 5.1.2.1 Insulation resistance and polarization index Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 51) 1MB155 / 1MB555 SH 71 ... 355 50 Operating Instructions, 12/2018, A5E41926185A Assembly 5.1 Preparations for installation 5.1.2.2 Testing the insulation resistance and polarization index WARNING Hazardous voltage at the terminals During and immediately after measuring the insulation resistance or the polarization index (PI) of the stator winding, hazardous voltages may be present at some of the terminals. Contact with these can result in death, serious injury or material damage. * If any power cables are connected, check to make sure line supply voltage cannot be delivered. * Discharge the winding after measurement until the risk is eliminated, e.g. using the following measures: - Connect the terminals with the ground potential until the recharge voltage drops to a non-hazardous level - Attach the connection cable. Measure the insulation resistance 1. Before you begin measuring the insulation resistance, please read the operating manual for the insulation resistance meter you are going to use. 2. Short-circuit the ends of the temperature sensor cables before applying the test voltage. If the test voltage is connected to only one temperature sensor terminal, the temperature sensor will be destroyed. 3. Make sure that no power cables are connected. 4. Measure the winding temperature and the insulation resistance of the winding in relation to the machine enclosure. The winding temperature should not exceed 40 C during the measurement. Convert the measured insulation resistances in accordance with the formula to the reference temperature of 40 C. This thereby ensures that the minimum values specified can be compared. 5. Read out the insulation resistance one minute after applying the measuring voltage. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 51 Assembly 5.1 Preparations for installation Limit values for the stator winding insulation resistance The following table specifies the measuring voltage and limit values for the insulation resistance. These values correspond to IEEE 43-2000 recommendations. Table 5- 1 Stator winding insulation resistance at 40 C UN Umeas V M U 1000 500 5 1000 U 2500 500 (max. 1000) 100 2500 < U 5000 1000 (max. 2500) 5000 < U 12000 2500 (max. 5000) U > 12000 5000 (max. 10000) V RC Urated = rated voltage, see the rating plate Umeas = DC measuring voltage RC = minimum insulation resistance at a reference temperature of 40 C Conversion to the reference temperature When measuring with winding temperatures other than 40 C, convert the measuring value to the reference temperature of 40 C according to the following equations from IEEE 432000. (1) RC = KT * RT (2) KT = (0.5) (40-T)/10 RC Insulation resistance converted to 40 C reference temperature KT Temperature coefficient according to equation (2) RT Measured insulation resistance for measuring/winding temperature T in C 40 Reference temperature in C 10 Halving/doubling of the insulation resistance with 10 K T Measuring/winding temperature in C In this case, doubling or halving the insulation resistance at a temperature change of 10 K is used as the basis. The insulation resistance halves every time the temperature rises by 10 K. The resistance doubles every time the temperature falls by 10 K. For a winding temperature of approx. 25 C, the minimum insulation resistances are 20 M (U 1000 V) or 300 M (U > 1000 V). The values apply for the complete winding to ground. Twice the minimum values apply to the measurement of individual assemblies. Dry, new windings have an insulation resistance of between 100 and 2000 M, or possibly even higher values. An insulation resistance value close to the minimum value could be due to moisture and/or dirt accumulation. The size of the winding, the rated voltage and other characteristics affect the insulation resistance and may need to be taken into account when determining measures. Over its operating lifetime, the motor winding insulation resistance can drop due to ambient and operational influences. Calculate the critical insulation resistance value depending on the rated voltage by multiplying the rated voltage (kV) by the specific critical resistance value. Convert the value for the current winding temperature at the time of measurement, see above table. 1MB155 / 1MB555 SH 71 ... 355 52 Operating Instructions, 12/2018, A5E41926185A Assembly 5.2 Installing the machine Measuring the polarization index 1. To determine the polarization index, measure the insulation resistances after one minute and ten minutes. 2. Express the measured values as a ratio: PI = Rinsul 10 min / Rinsul 1 min Many measuring devices display these values automatically following the measurement. For insulation resistances > 5000 M, the measurement of the PI is no longer meaningful and consequently not included in the assessment. R(10 min) / R(1 min) Assessment 2 Insulation in good condition <2 Dependent on the complete diagnosis of the insulation NOTICE Damage to insulation If the critical insulation resistance is reached or undershot, this can damage the insulation and cause voltage flashovers. * Contact the service center (Page 145). * If the measured value is close to the critical value, you must subsequently check the insulation resistance at shorter intervals. See also Insulation resistance and polarization index (Page 50) Limit values of the anti-condensation heating insulation resistance The insulation resistance of the anti-condensation heating with respect to the machine housing should not be lower than 1 M when measured at 500 V DC. 5.2 Installing the machine 5.2.1 Preparing the assembly area 1. Prepare a suitable assembly area (e.g. assembly stands). Make sure that the assembly area has sufficient clearance from the floor for the DE shaft end. The necessary data is provided in the machine dimension drawing. 2. Refer to the shipping documents to check that all motor components are available for assembly. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 53 Assembly 5.2 Installing the machine For vertical installation, use all of the eyebolts provided and when necessary, hoisting straps (DIN EN 1492-1) and/or lashing straps (DIN EN 12195-2) to stabilize the position of the motor. Prevent foreign bodies from falling into the fan cover. For vertical machine installation with the shaft end facing downwards, attach a protective canopy. If the shaft extension is facing upwards, the user must prevent liquid from moving along the shaft and entering the motor. Clean bare metal surfaces with anti-corrosion agent using white spirit to ensure proper installation and / or machine mounting. Do not obstruct the ventilation! Do not draw in the discharged air directly - also from adjacent equipment. Avoid exposing them to direct, intense solar radiation, rain, snow, ice, or also dust for extended periods. Attach a covering structure or an additional cover when using or storing outdoors. Do not exceed the permissible axial and radial forces. Only use explosion-protected machines in appropriate areas in accordance with directive 1999/92/EC. If the certification is supplemented by an X, please note the special conditions in the EC type examination certificate. Special conditions for explosion-proof machines (Page 17) When installing electrical systems in hazardous zones, observe EN/IEC 60079-14 and the corresponding country regulations. The machine temperature class specified on the rating plate must be equal to or greater than the temperature class of any combustible gases that may develop. Select optional mounted equipment according to the requirements of Directive 2014/34/EU. 5.2.2 Balancing The rotor is dynamically balanced. For shaft extensions with feather keys, the balancing type is specified using the following coding on the face of the drive end of the shaft: "H" means balancing with a half feather key (standard) "F" means balancing with a whole feather key "N" means balancing without a featherkey. 1MB155 / 1MB555 SH 71 ... 355 54 Operating Instructions, 12/2018, A5E41926185A Assembly 5.2 Installing the machine CAUTION Risk of injury due to Incorrect installation or removal If the required touch protection measures for drive output elements are not observed this can result in physical injury and material damage. * The general touch protection measures for drive output elements must be observed. * Drive output elements may only be pushed on or pulled off with the correct equipment. * The feather keys are only locked against falling out during shipping. If you commission a machine without a drive output element, the feather keys must be secured to prevent them from being thrown out. The featherkey data on the shaft and transmission element must indicate the correct type of balancing in each case and must be correctly mounted. The balancing quality corresponds to vibration severity grade "A" for the complete machine; vibration severity grade "B" is possible as an option, i.e. in order to ensure the desired balancing quality, it must be ensured that the featherkey data on the hub and machine shaft complement each other in the case of a shorter or longer output transmission element. Align the offset at the coupling between electrical machines and the driven machines so that the maximum permissible vibration values according to ISO 10816-3 are not exceeded. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 55 Assembly 5.3 Alignment and fastening 5.2.2.1 Mounting and withdrawing output transmission elements Withdrawing output transmission elements Mounting output transmission elements When mounting output transmission elements (coupling, gear wheel, belt pulley etc. ) use the thread at the shaft end. If possible, heat up the output transmission elements as required. Use a suitable device when withdrawing output elements. When mounting or withdrawing, do not apply any blows, for example with a hammer or similar tool, to the parts to be mounted or withdrawn. Only transfer radial or axial forces specified in the catalog to the motor bearings via the shaft extension. 5.3 Alignment and fastening Observe the following when aligning and mounting: Ensure a flat and uniform contact surface for foot and flange mounting. When mounting on the wall, support the machine from below, e.g. using a bracket, or bolt it. Precisely align the machine when couplings are used. Ensure that the mounting surfaces are clean and free of any dirt. Remove any anti-corrosion protection using white spirit. Avoid installation-related resonances with the rotating frequency and twice the line frequency. 1MB155 / 1MB555 SH 71 ... 355 56 Operating Instructions, 12/2018, A5E41926185A Assembly 5.3 Alignment and fastening Note any unusual noise when the rotor is manually turned. Check the direction of rotation with the motor uncoupled. Avoid rigid couplings. Repair any damage to the paint, this must be done immediately and correctly. 5.3.1 Repainting/touching up the paint finish of explosion-protected machines Note Repainting/touching up the paint finish of explosion-protected machines For explosion-protected machines, observe the information in Chapter Repainting/touching up. 5.3.2 Measures for alignment and mounting The following measures are required in order to compensate any radial offset at the coupling and to horizontally adjust the electrical machine with respect to the driven load: Vertical positioning For vertical mounting positions, avoid deforming the machines by placing shims under the mounting feet. Keep the number of shims low; only use a few stacked shims. Horizontal positioning To position the machine horizontally, shift it sideways on the foundation and ensure that the axial position is maintained (angularity error). When positioning the motor, ensure that a uniform axial gap is maintained around the coupling. Smooth running Preconditions for smooth, vibration-free operation: - Stable foundation design free of any shock or vibration. - A precisely aligned coupling. - A well-balanced drive output element (coupling, belt pulleys, fans, ...) Maintain the maximum permissible vibration values in operation according to ISO 108163. Avoid inadmissible vibration caused by imbalance, for example (drive output element), external vibration or any resonance over the complete speed range. It may be necessary to completely balance the machine with the drive output element or the system resonance frequency must be shifted. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 57 Assembly 5.4 Installing the machine Foot mounting/flange mounting - Use the specified thread size laid down in EN 50347 when flanging the machine to a foundation or a machine flange. - Mount the machine at all the foot or flanged holes provided.

When selecting the bolts and the design of the foundation, take into account the maximum forces occurring in the case of a fault such as short circuit or system transfers in phase opposition, etc. Request the foundation force values from the Service Center if required. See also Tightening torques for screw and bolt connections (Page 147) 5.4.2.2 Horizontal types of construction with mounting feet 1. Refer to any instructions for aligning the driven machine and those of the coupling manufacturer. 2. Align the machines with coupling output to the driven machine in such a manner that the center lines of the shafts are parallel with no offset. This ensures that no additional forces affect their bearings during operation. 3. For the vertical positioning (x0) place thin shims under the machine feet. The number of shims should be kept as low as possible, i.e. stack as few as possible. This also prevents the machine being subjected to any stress/distortion. If available, use the existing tapped holes for the forcing-off bolts to somewhat raise the machine. 4. When positioning the machine, ensure that a uniform axial gap (y0) is maintained around the coupling. 5. Fix the machine to the foundation. The choice of fixing elements depends on the foundation and is the plant operator's responsibility. Note Machine expansion When aligning, make allowance for the thermal expansion of the machine when the temperature increases. 5.4.2.3 Horizontal types of construction with flange The standard flange is provided with a centering. The choice of fit for the mating flange on the driven machine is the system manufacturer's or the plant operator's responsibility. If the machine is not fitted with a standard flange, align the machine to suit the driven machine. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 59 Assembly 5.4 Installing the machine Procedure The machine axis must be horizontal when it is lifted and the flange must be parallel to the mating flange, so as to avoid seizing and stressing. Otherwise damage to the centering will result. 1. Grease the centering flange with assembly paste to make the process easier. 2. Screw three studs into tapped holes spaced about 120 apart around the driven machine flange. The studs act as positioning aids. 3. Position the machine so that its axis is aligned with that of the driven machine, but not yet quite touching. Advance the machine slowly towards the driven machine; advancing too quickly risks damaging the centering. 4. If necessary, rotate the machine into the right position so that the clearance holes in the flange are central to the tapped holes. 5. Move the machine fully up against the mating flange so that it is fully in contact. 6. Fix the machine using the flange fixing bolts, finishing by replacing the studs. 5.4.2.4 Vertical types of construction with flange The standard flange is provided with a centering. The choice of fit for the mating flange on the driven machine is the system manufacturer's or the plant operator's responsibility. If the machine is not fitted with a standard flange, align the machine to suit the driven machine. Procedure The machine axis must be vertical when it is lifted and the flange must be parallel to the mating flange, so as to avoid seizing and stressing. Otherwise damage to the centering will result. 1. Grease the centering flange with assembly paste to make the process easier. 2. Screw in two studs into tapped holes on opposite sides of the driven machine flange. The studs act as positioning aids. 3. Lower the machine slowly toward the driven machine and into the centering, so that the flanges do not quite touch. Lowering too quickly risks damaging the centering. 4. If necessary, rotate the machine into the right position so that the clearance holes in the flange are central to the tapped holes. 5. Lower the machine completely onto the mating flange so that it is fully in contact; then remove the studs. 6. Fix the machine using the flange fixing bolts. 1MB155 / 1MB555 SH 71 ... 355 60 Operating Instructions, 12/2018, A5E41926185A Assembly 5.4 Installing the machine 5.4.2.5 Type of construction without flange If the motor is not fitted with a flange, align the motor to suit the driven machine. For types of construction without flange (e.g. IM B3), use suitable covers to ensure that no small parts can fall down between the transmission element and the bearing shield on the drive side. 5.4.3 Removing the rotor shipping brace If a rotor shipping brace is attached to the machine, remove it at the last possible moment, for example, when you are ready to push on the output or drive element. Store the rotor locking device Be sure to store the rotor locking device. It must be remounted for possible disassembly and transport. Details about the alignment accuracy can be found in the Section "Information about the machine dimension drawing". 5.4.4 Recommended alignment accuracy The alignment accuracy required depends essentially on the configuration of the overall machine train. Observe the required alignment accuracy of the coupling manufacturer in all cases when aligning the machine. Table 5- 2 Recommended alignment accuracy Speed rpm Parallel offset mm Angular offset mm per 100 mm coupling diameter 750 0.09 0.09 1500 0.06 0.05 3000 0.03 0.025 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 61 Assembly 5.4 Installing the machine 5.4.5 Mounting the output elements Balance quality The rotor is dynamically balanced. For shaft ends with feather keys, the balancing type is specified using the following coding on the rating plate: "H" means balancing with a half feather key "F" means balancing with a whole feather key "N" means balancing without a featherkey. Figure 5-1 Balancing type on the drive-end side Pushing on the power output elements Requirements: - The coupling and/or the output element must be appropriately dimensioned for the operating case at hand. - Comply with the coupling manufacturer's instructions. - Make sure that the balancing type of the transmission element correctly matches the type of balance of the rotor. - Use only ready drilled and balanced transmission elements. Check the hole diameters and the balancing status before pulling them on. Thoroughly clean the shaft extension. Pulling on: - Warm up the drive output elements to expand them before pulling them on. Select the temperature difference for the heating process to suit the coupling diameter, fit and material. See the coupling manufacturer's instructions. - Power output elements may only be pushed on or pulled off with the correct equipment. The transmission element must be pulled on in one continuous operation via the front thread holes in the shaft or pushed on by hand. - Do not use a hammer, as this will damage the bearings. 1MB155 / 1MB555 SH 71 ... 355 62 Operating Instructions, 12/2018, A5E41926185A Assembly 5.4 Installing the machine Shaft extensions with feather key To maintain the balancing quality, you have the following options: If the transmission element is shorter than the feather key with balancing type "H", then you must machine off the section of feather key protruding from the shaft contour and transmission element in order to maintain the balance quality. If the transmission element is drawn up on to the shoulder of the shaft, you must ensure that the part of the coupling groove where the feather key is not inserted is taken into consideration when balancing the coupling. The following applies to all four-pole machines with a frequency 60 Hz: The feather key must be shortened if the coupling hub is shorter than the feather key. The center of gravity of the coupling half should be within the length of the shaft end. The coupling used must be prepared for system balancing. Danger as a result of a feather key being flung out Rotating parts are dangerous. The feather keys are only locked against falling out during shipping. If a machine with 2 shaft extensions does not have an output element on one shaft extension, the feather key can be flung out during operation. Rotating parts can result in death, serious injury or material damage. Do not operate the machine unless the transmission elements have been pulled on. On shaft extensions without drive output element, take suitable measures to ensure that the feather key cannot be flung out. For balancing type "H", shorten the feather key by about half. 5.4.6 Axial and radial forces You can obtain the permissible values for axial and radial forces by contacting the Service Center or referring to the machine catalog. WARNING Damage to bearings or the shaft Large output masses and their centers of gravity outside the shaft extensions can lead to resonance in operation. This can result in damage to the bearings and shaft. In an explosive atmosphere, there is a risk of explosion. Death, serious injury, or material damage can result. * Ensure that the permissible loads for the forces on the shaft extension are adhered to in accordance with the catalog data or configuration data. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 63 Assembly 5.4 Installing the machine 1MB155 / 1MB555 SH 71 ... 355 64 Operating Instructions, 12/2018, A5E41926185A Electrical connection 6 Observe the following when carrying out any work on the machine: Comply with the general safety instructions (Page 11) Comply with the applicable national and sector-specific regulations.

Preferably use end sleeves instead of soldering cable ends. 2. Before connecting, attach the end sleeves so as to form a technically correct, currentcarrying crimped joint at the end of the conductor. WARNING Risk of explosion due to excessive temperature rise If the end of the conductor is not correctly enclosed by the end sleeve, but is trapped by it, this can lead to overheating. The temperature class of the machine can be exceeded. This can trigger ignition of an explosive mixture. This can result in death, serious injury or material damage. * Insert only one conductor end into each end sleeve. Attach the end sleeve correctly. 6.5.2 Connecting aluminum conductors If you are using aluminum conductors, then comply with the following: Use only cable lugs that are suitable for connecting aluminum conductors. Immediately before inserting the aluminum conductor, remove the oxide layer from the contact areas on the conductor and/or the mating piece. Do this using a brush or file. Then grease the contact areas immediately using neutral Vaseline. This prevents a new oxide layer from forming. NOTICE Aluminum flow due to contact pressure Aluminum flows following installation due to the contact pressure. The connection using clamping nuts can loosen as a result. The contact resistance increases, obstructing the current from being conducted. This can result in fire and material damage to the machine - or even in total failure, as well as material damage to the plant or system due to machine failure. * Retighten the clamping nuts after approximately 24 hours and then again after approximately four weeks. Make sure that the terminals are de-energized before you tighten the nuts. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 77 Electrical connection 6.6 Connecting converters 6.6 Connecting converters NOTICE Excessively high supply voltage Material damage can occur if the supply voltage is too high for the insulation system.

It may be necessary to perform further checks and tests in accordance with the specific situation on-site. Once the system has been correctly installed, you should check the following prior to commissioning: The machine is undamaged. The machine has been properly installed and aligned. The output transmission elements are set correctly for their type, e.g. alignment and balancing of couplings, belt forces in the case of a belt drive, tooth forces and tooth-flank backlash in the case of geared output, radial and axial clearance in the case of coupled shafts. All fixing screws, connection elements, and electrical connections have been tightened to the specified tightening torques. The operating conditions match the data provided in accordance with the technical documentation, such as degree of protection, ambient temperature, etc.. Moving parts, for example the coupling, move freely. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 81 Start-up 7.2 Measures before commissioning All touch protection measures for moving and live parts have been taken. Screwed-in lifting eyes are removed after installation or secured to prevent them from becoming loose. See also Tightening torques for screw and bolt connections (Page 147) Second shaft extension If the second shaft extension is not used: Carefully secure the feather key to prevent it from being thrown out, and for balancing type "H" (standard type), ensure its weight is reduced to approximately 60 % of the original value. Using covers, carefully secure the unused shaft extension so that it cannot be touched. Risk of losing the IP degree of protection as a result of damaged shaft sealing rings This can result in death, serious injury, or material damage. Replace damaged components immediately. Rotate the rotor to ensure that it does not touch the stator. Ensure that the bearing insulation is not bridged/jumpered. Using the appropriately designed and adjusted control and speed monitoring functions ensure that the permissible speeds specified on the rating plate cannot be exceeded. Ensure that any supplementary equipment used to monitor the motor is correctly connected and is functioning. Electrical connection Carefully check the grounding and potential bonding connections. Connect the machine corresponding to the specified direction of rotation. Using the appropriate open-loop control and speed monitoring functions, carefully ensure that no higher speeds can be achieved than are permitted and specified in the technical data. For this purpose, compare the data on the rating plate or, if necessary, the systemspecific documentation. Comply with the minimum insulation resistances. Comply with the minimum air clearances. Correctly connect possibly available machine monitoring devices and equipment - and carefully ensure that they are functioning correctly. Check the correct functioning of the brakes or backstops. Set the values for "Alarm" and "Shutdown" at the monitoring devices. Carefully ensure that temperature-sensitive parts and components, e.g. cables are not in contact with the machine enclosure. 1MB155 / 1MB555 SH 71 ... 355 82 Operating Instructions, 12/2018, A5E41926185A Start-up 7.2 Measures before commissioning Converter operation If the motor design requires connection to a specific converter type, carefully check the supplementary data on the rating plate/supplementary plate. Ensure that the converter is correctly parameterized. Depending on the design, you will find some parameterization data on the rating plate of the machine. Further information is provided in the converter documentation. If necessary, contact the Service Center. Check that the supplementary equipment and devices to monitor the machine are correctly connected and are functioning correctly. In continuous operation, carefully ensure that the motor cannot exceed the specified upper speed limit nmax or fall below the lower speed limit nmin. The permissible acceleration time to the limit speed nmin depends on the parameter assignment. 7.2.1 Insulation resistance and polarization index Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 84) 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 83 Start-up 7.2 Measures before commissioning 7.2.2 Testing the insulation resistance and polarization index WARNING Hazardous voltage at the terminals During and immediately after measuring the insulation resistance or the polarization index (PI) of the stator winding, hazardous voltages may be present at some of the terminals. Contact with these can result in death, serious injury or material damage. * If any power cables are connected, check to make sure line supply voltage cannot be delivered. * Discharge the winding after measurement until the risk is eliminated, e.g. using the following measures: - Connect the terminals with the ground potential until the recharge voltage drops to a non-hazardous level - Attach the connection cable. Measure the insulation resistance 1. Before you begin measuring the insulation resistance, please read the operating manual for the insulation resistance meter you are going to use. 2. Short-circuit the ends of the temperature sensor cables before applying the test voltage. If the test voltage is connected to only one temperature sensor terminal, the temperature sensor will be destroyed. 3. Make sure that no power cables are connected. 4. Measure the winding temperature and the insulation resistance of the winding in relation to the machine enclosure. The winding temperature should not exceed 40 C during the measurement. Convert the measured insulation resistances in accordance with the formula to the reference temperature of 40 C. This thereby ensures that the minimum values specified can be compared. 5. Read out the insulation resistance one minute after applying the measuring voltage. 1MB155 / 1MB555 SH 71 ... 355 84 Operating Instructions, 12/2018, A5E41926185A Start-up 7.2 Measures before commissioning Limit values for the stator winding insulation resistance The following table specifies the measuring voltage and limit values for the insulation resistance. These values correspond to IEEE 43-2000 recommendations. Table 7- 1 Stator winding insulation resistance at 40 C UN Umeas V V RC M U 1000 500 5 1000 U 2500 500 (max. 1000) 100 2500 < U 5000 1000 (max. 2500) 5000 < U 12000 2500 (max. 5000) U > 12000 5000 (max. 10000) Urated = rated voltage, see the rating plate Umeas = DC measuring voltage RC = minimum insulation resistance at a reference temperature of 40 C Conversion to the reference temperature When measuring with winding temperatures other than 40 C, convert the measuring value to the reference temperature of 40 C according to the following equations from IEEE 432000. (1) RC = KT * RT (2) KT = (0.5) (40-T)/10 RC Insulation resistance converted to 40 C reference temperature KT Temperature coefficient according to equation (2) RT Measured insulation resistance for measuring/winding temperature T in C 40 Reference temperature in C 10 Halving/doubling of the insulation resistance with 10 K T Measuring/winding temperature in C In this case, doubling or halving the insulation resistance at a temperature change of 10 K is used as the basis. The insulation resistance halves every time the temperature rises by 10 K. The resistance doubles every time the temperature falls by 10 K. For a winding temperature of approx. 25 C, the minimum insulation resistances are 20 M (U 1000 V) or 300 M (U > 1000 V). The values apply for the complete winding to ground. Twice the minimum values apply to the measurement of individual assemblies. Dry, new windings have an insulation resistance of between 100 and 2000 M, or possibly even higher values. An insulation resistance value close to the minimum value could be due to moisture and/or dirt accumulation. The size of the winding, the rated voltage and other characteristics affect the insulation resistance and may need to be taken into account when determining measures. Over its operating lifetime, the motor winding insulation resistance can drop due to ambient and operational influences. Calculate the critical insulation resistance value depending on the rated voltage by multiplying the rated voltage (kV) by the specific 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 85 Start-up 7.2 Measures before commissioning critical resistance value. Convert the value for the current winding temperature at the time of measurement, see above table. Measuring the polarization index 1. To determine the polarization index, measure the insulation resistances after one minute and ten minutes. 2. Express the measured values as a ratio: PI = Rinsul 10 min / Rinsul 1 min Many measuring devices display these values automatically following the measurement. For insulation resistances > 5000 M, the measurement of the PI is no longer meaningful and consequently not included in the assessment. R(10 min) / R(1 min) Assessment 2 Insulation in good condition <2 Dependent on the complete diagnosis of the insulation NOTICE Damage to insulation If the critical insulation resistance is reached or undershot, this can damage the insulation and cause voltage flashovers. * Contact the service center (Page 145). * If the measured value is close to the critical value, you must subsequently check the insulation resistance at shorter intervals. See also Insulation resistance and polarization index (Page 83) Limit values of the anti-condensation heating insulation resistance The insulation resistance of the anti-condensation heating with respect to the machine housing should not be lower than 1 M when measured at 500 V DC. 7.2.3 Testing the cooling of the machine Cooling Check that the machine cooling is available for commissioning. See also Preparations for use (Page 31) 1MB155 / 1MB555 SH 71 ... 355 86 Operating Instructions, 12/2018, A5E41926185A Start-up 7.2 Measures before commissioning 7.2.4 Commissioning an external fan The external fan ensures that the machine is cooled irrespective of the machine speed or direction of rotation. The external fan is only suitable for one direction of rotation. Checks before the first test run Before the first test run, carry out the following checks: The external fan is correctly fitted and aligned. The rotor runs freely. All of the retaining elements and electrical connections are securely tightened. The grounding and equipotential bonding connections to the mains have been correctly made. The air flow is not impeded or shut off by flaps, covers or similar. If the cooling air is in open circulation, it has only weak, chemically abrasive properties and a low dust content. All protection measures have been taken to prevent accidental contact with moving or live parts. Performing the test run 1. Switch the external fan motor on and off briefly. 2. Compare the direction of rotation of the external fan with the specified direction of rotation. The direction of rotation of the external fan is indicated with an arrow on the fan cover specifying the direction of rotation or with a terminal designation on the rating plate of the external fan unit. Depending on the version, the fan impeller is visible through the air inlet opening in the fan cover on the external fan motor. 3. If the direction of rotation is wrong, then interchange two line cables in the external fan motor terminal box. Note Use these operating instructions for motors with external fans. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 87 Start-up 7.3 Switching on 7.2.5 Setpoint values for monitoring the bearing temperature Prior to commissioning If the machine is equipped with bearing thermometers, set the temperature value for disconnection on the monitoring equipment before the first machine run.

To do this, close the circuit breaker and do not switch the machine off prematurely. Switching the machine off again while it is starting up and still running at slow speed should be kept to a bare minimum, for example for checking 1MB155 / 1MB555 SH 71 ... 355 88 Operating Instructions, 12/2018, A5E41926185A Start-up 7.3 Switching on the direction of rotation or for checking in general. Allow the machine to run to a standstill before switching it back on again. Check mechanical operation for noise or vibration at the bearings or end shields. If the machine is not running smoothly or is emitting abnormal noises, switch it off, and determine the cause of the fault as it runs down. If mechanical operation improves immediately after the machine is switched off, then the cause is magnetic or electrical, e.g. voltage imbalance, magnetic imbalance. If mechanical operation does not improve immediately after switching the machine off, then the cause is mechanical, e.g. an imbalance in the electrical machines or in the driven machine, inadequate alignment of the machine set, operation of the machine with the system resonating (system = machine + base frame + foundations etc.). If the machine runs perfectly in terms of its mechanical operation, switch on any cooling devices present and continue to monitor the machine for a while as it idles. If it runs perfectly, connect a load. Check that it runs smoothly. Read off and document the values for voltage, current, and power. Where possible, read off corresponding values for the driven machine and document them as well. Monitor the bearing temperature, winding temperature, etc. until the system reaches a steady state. Document these, provided this is possible with existing measuring instruments. NOTICE Destruction of the machine The machine can be destroyed if the vibration values are not strictly complied with. * In operation, maintain vibration values in accordance with DIN ISO 10816-3. Start the machine without a load; to do this, close the motor starter protector and do not switch the machine off prematurely. You should limit how often you switch the machine off while it is starting up and still running at a slow speed, for checking the direction of rotation or the required dimensions, for example. Allow machines to reach a standstill before switching them back on. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 89 Start-up 7.3 Switching on 7.3.1 Test run After installation or inspection, carry out a test run: 1. Start up the machine without a load. To do this, close the circuit breaker and do not switch off prematurely. Check whether it is running smoothly. Switching the machine off again while it is starting up and still running at slow speed should be kept to a bare minimum, for example for checking the direction of rotation or for checking in general. Allow the machine to run down before switching it on again. 2. If the machine is running smoothly and evenly, switch on the cooling equipment. Continue to observe the machine for a while in no-load operation. 3. If it runs perfectly, connect a load. NOTICE Thermal overload of motors connected directly to the line supply In addition to the load torque, the ramp-up (accelerating) time is essentially influenced by the moment of inertia to be accelerated. While ramping up when connected to the line supply, the inrush (starting) current is a multiple of the rated current. This can result in thermal overload. This can damage the motor. As a consequence, when ramping up, observe the following: * Monitor the ramp-up time and number of consecutive starts. * Comply with the limit values and/or ramp-up conditions specified in the catalog or the order documentation. 4. During the test run, check and document the following: - Check whether it is running smoothly. - Document the voltage, current and power values. As far as possible, document the corresponding values of the driven machine. - If this is possible using the available measuring equipment, check the bearing and stator winding temperatures until they have reached steady-state values. - Check the machine for noise or vibrations on the bearings or bearing shields as it runs. 1MB155 / 1MB555 SH 71 ... 355 90 Operating Instructions, 12/2018, A5E41926185A Start-up 7.3 Switching on 5. In case of uneven running or abnormal noise, switch off the machine. As the machine runs down, identify the cause. - If the mechanical operation improves immediately after the machine is switched off, then the cause is magnetic or electrical. - If the mechanical running does not improve immediately after switching the machine off, then the cause is mechanical. - Imbalance of the electrical machine or the driven machine - The machine set has not been adequately aligned - The machine is being operated at the system resonance point. System = motor, base frame, foundation, ... NOTICE Serious damage to the machine If the vibration values in operation are not maintained in accordance with DIN ISO 10816-3, then the machine can be mechanically destroyed. * During operation, observe the vibration values in accordance with DIN ISO 10816-3. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 91 Start-up 7.3 Switching on 1MB155 / 1MB555 SH 71 ... 355 92 Operating Instructions, 12/2018, A5E41926185A 8 Operation Observe the following when carrying out any work on the machine: Comply with the general safety instructions (Page 11) Comply with the applicable national and sector-specific regulations.

Switching on the machine with anti-condensation heating (optional) CAUTION Machine overheating Minor injury or material damage can occur if you do not observe the following: * If available, switch off the anti-condensation heating each time before switching on. Explosion hazard from hybrid mixtures Hybrid mixtures are mixtures of flammable dusts with explosive gas/air atmospheres which can together create a dangerous explosive atmosphere if they occur at the same time. Changes can arise in the safety characteristics here, such as a change in the zonal classification, increase in the explosion pressure, reduction in the minimum ignition energy and a reduction in the maximum temperatures to be observed. An explosion can result. This can result in death, serious injury or material damage. For this reason, the relative characteristics must be considered both for gas (zones 0, 1 and 2) and for dust (zones 20, 21 and 22) where hybrid mixtures arise. It is necessary for a competent assessor to determine in the individual case whether the parameters determining ignition are unfavorably affected in a particular hybrid mixture. Motors with dual plates for G ("Gas") and D ("Dust") may only be used where these two occur after prior examination of the properties of the hybrid mixtures by the user. Explosion hazard due to overheating of the machine caused by a layer of dust Deposits of dust have a thermal insulation effect, which can lead to the machine overheating. The maximum surface temperature of the machine cannot be adhered to. The dust can ignite, resulting in an explosion. This can result in death, serious injury or material damage. Dust the machine regularly. Do not allow dust layers thicker than 5 mm to build up on the machine surface. Do not switch the machine on until the dust has been removed. 1MB155 / 1MB555 SH 71 ... 355 96 Operating Instructions, 12/2018, A5E41926185A Operation 8.1 Safety instructions for operation Risk of explosion due to excessive bearing temperature The surface temperature cannot be maintained within maximum permissible limits if the bearing becomes too hot. The dust can ignite, resulting in an explosion. This can result in death, serious injury or material damage. Monitor the bearing temperature. In addition to the current-dependent overload protection device located in the three phases of the connecting cable, we recommend that you also monitor the temperature rise in the machine using temperature sensors integrated in the stator winding. 8.1.1 Static charging when cleaning Risk of explosion due to static charging If you clean the motor, plastic components may become statically charged and ignite a potentially explosive atmosphere. An explosion can occur. This can result in death, serious injury or material damage. When cleaning ensure that there is absolutely no explosive atmosphere present. Clean the plastic parts and components so that absolutely no static charging occurs Do not use compressed air for cleaning. 8.1.2 Safety note for ventilation CAUTION Risk of injury when touching the fan There is a risk of injury at machines equipped with a fan cover (e.g. on machines in the textile industry), as the fan is not completely touch protected. * Do not touch the rotating fan. * Do not put your fingers into the larger air discharge openings. * Prevent manual intervention by using suitable measures, e.g. appropriate housings or a protective grating. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 97 Operation 8.1 Safety instructions for operation Forced ventilation (optional): Type of cooling IC 416 in accordance with EN / IEC 60034-6 WARNING Risk of burning Operating the machine without external fan results in overheating. This may result in death, personal injury and material damage. * Never commission the machine without an external fan. 8.1.3 Bridging insulated bearings Explosion hazard if the bridging is removed from the insulated bearing Removing the factory-fitted bridging of the insulated bearing leads to potential differences between the rotor and the grounded motor. This can cause the generation of sparks, which especially in an explosive atmosphere can ignite surrounding dust or combustible gases. Explosions can occur. There is also a risk of an electric shock. Death, serious injury, or material damage will result. Do not open the bridging of the bearing insulation during operation. 8.1.4 Switching on with the anti-condensation heating active Excessively high machine temperature when heating is switched on If the anti-condensation heating is operated while the machine is running, this can increase the temperatures inside the machine. Material damage can result. Make sure that the anti-condensation heating is switched off before the machine is switched on. Only operate anti-condensation heating when the machine is switched off. WARNING Explosion hazard If the anti-condensation heating is switched on during operation, the temperature class or the maximum surface temperature of the machine can be exceeded. In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious injury or material damage. Only switch the anti-condensation heating on after the motor has been switched off. 1MB155 / 1MB555 SH 71 ... 355 98 Operating Instructions, 12/2018, A5E41926185A Operation 8.2 Switching on the machine 8.2 Switching on the machine 1. If at all possible, run the machine without load and check that it is running smoothly. 2. If it runs perfectly, connect a load. NOTICE Thermal overload of motors connected directly to the line supply In addition to the load torque, the ramp-up (accelerating) time is essentially influenced by the moment of inertia to be accelerated. While ramping up when connected to the line supply, the inrush (starting) current is a multiple of the rated current. This can result in thermal overload. This can damage the motor. As a consequence, when ramping up, observe the following: * Monitor the ramp-up time and number of consecutive starts. * Comply with the limit values and/or ramp-up conditions specified in the catalog or the order documentation. 3. If this is possible using the available measuring equipment, check the bearing and stator winding temperatures. 8.3 Switching off the external fan Do not immediately switch off the separately-driven (external) fan after switching off the machine. First wait for the machine to cool down. This will prevent the accumulation of residual heat. 8.4 Switching on again after an emergency switching-off Check the machine before recommissioning the driven machine after an Emergency Off. Eliminate all the causes that have led to the emergency off 8.5 Stoppages The stoppage is a shutdown for a period of time, during which the machine is stopped but remains at the location of use. Under normal ambient conditions, e. g. the stopped machine is not exposed to any vibration, no increased level of corrosion, etc. in general, the following measures are necessary during stoppages. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 99 Operation 8.5 Stoppages Longer non-operational periods Note * For longer non-operational periods (> 1 month), either operate the machine or at least turn the rotor regularly, approximately once per month. * Please refer to the section "Switching on" before switching on to recommission the motor. * Remove any machine rotor locking devices before you turn the rotor. NOTICE Restricted motor function If not used for longer periods of time, material damage or complete motor failure can occur. If the motor is out of service for a period of more than 12 months, then environmental effects can damage the motor. * Apply suitable corrosion protection, preservation, packing and drying measures. Switching on the anti-condensation heater Switch on any anti-condensation heating while the machine is not being operated. Taking the machine out of service Details regarding the necessary measures, Chapter Preparations for use (Page 31). Lubricating before recommissioning NOTICE Dry running bearings Bearings can be damaged if they do not have sufficient grease. * Re-grease the bearings if they have been out of service for more than one year. The shaft must rotate so that the grease can be distributed in the bearings. Observe the data on the lubricant plate.

In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious injury or material damage. * Only switch on the anti-condensation heating after the motor has been switched off. Carefully comply with the data on the anti-condensation heating plate. 8.5.1 Avoidance of damage to rolling bearings during stoppages Extended stoppages at the identical or almost identical resting position of the rotor in the rolling bearings can result in damage, such as brinelling or corrosion. During stoppages, regularly start up the machine for a brief period once a month. As a minimum, turn the rotor several times. If you have uncoupled the machine from the driven machine and secured the rotor with a rotor shipping brace, then remove this before turning the rotor over or starting up the machine. Make sure that the resting position of the rotor after the rotor has been turned over is different from its previous position. Use the fitted key or the coupling halves as reference markers. During recommissioning, refer to the information in Chapter "Commissioning". See also Start-up (Page 81) 8.5.2 Decommissioning the machine Record the decommissioning steps. This log will be useful upon recommissioning. If the machine is going to be out of service for longer than six months, then take the necessary measures for preservation and storage. Otherwise, the machine could be damaged as a result of not being operated. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 101 Operation 8.6 faults 8.5.3 Re-commissioning the machine When you re-commission the machine, proceed as follows: Study the record made when the machine was decommissioned, and reverse the measures that were taken for conservation and storage.

Injuries can result. When cleaning using compressed air, make sure you use suitable extraction equipment and wear protective equipment (safety goggles, protective suit, etc.). NOTICE Damage to insulation If metal swarf enters the winding head when cleaning with compressed air, this can damage the insulation. Clearance and creepage distances can be undershot. This may cause damage to the machine extending to total failure. When cleaning with compressed air, ensure there is adequate extraction. 1MB155 / 1MB555 SH 71 ... 355 108 Operating Instructions, 12/2018, A5E41926185A Maintenance 9.2 Inspection and maintenance NOTICE Machine damage caused by foreign bodies Foreign bodies such as dirt, tools or loose components, such as screws etc., can be left by accident inside the machine after maintenance is performed. These can cause short circuits, reduce the performance of the cooling system or increase noise in operation. They can also damage the machine. * When carrying out maintenance work, make sure that no foreign bodies are left in or on the machine. * Securely attach all loose parts again once you have completed the maintenance procedures. * Carefully remove any dirt. Note Operating conditions and characteristics can vary widely. For this reason, only general intervals for inspection and maintenance measures can be specified here. Risk of explosion due to an increased surface temperature Components within the machine may be hotter than the maximum permissible surface temperature of the enclosure. In an explosive atmosphere, dust can ignite and an explosion occur. This can result in death, serious injury or material damage. Do not open the machine in an explosive and dusty atmosphere when it is still at normal operating temperature. Allow the machine to cool down before opening it. When disassembling, ensure that the parts necessary to seal the enclosure are not damaged, for example seals, face/plane mating surfaces. Perform a new routine test for the parts that have been repaired if these parts are crucial to ensure dust protection. Explosion hazard due to overheating of the machine caused by a layer of dust Deposits of dust have a thermal insulation effect, which can lead to the machine overheating. The maximum surface temperature of the machine cannot be adhered to. The dust can ignite, resulting in an explosion. This can result in death, serious injury or material damage. Dust the machine regularly. Do not allow dust layers thicker than 5 mm to build up on the machine surface. Do not switch the machine on until the dust has been removed. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 109 Maintenance 9.2 Inspection and maintenance Risk of explosion due to excessive bearing temperature The surface temperature cannot be maintained within maximum permissible limits if the bearing becomes too hot. The dust can ignite, resulting in an explosion. This can result in death, serious injury or material damage. Monitor the bearing temperature. In addition to the current-dependent overload protection device located in the three phases of the connecting cable, we recommend that you also monitor the temperature rise in the machine using temperature sensors integrated in the stator winding. 9.2.2 Static charging when cleaning Risk of explosion due to static charging If you clean the motor, plastic components may become statically charged and ignite a potentially explosive atmosphere. An explosion can occur. This can result in death, serious injury or material damage. When cleaning ensure that there is absolutely no explosive atmosphere present. Clean the plastic parts and components so that absolutely no static charging occurs Do not use compressed air for cleaning. 9.2.3 Inspections in the event of faults Natural disasters or unusual operating conditions, such as overloading or short circuit, are faults that overload the machine electrically or mechanically. Immediately perform an inspection after such faults. 1MB155 / 1MB555 SH 71 ... 355 110 Operating Instructions, 12/2018, A5E41926185A Maintenance 9.2 Inspection and maintenance 9.2.4 First inspection Check after approx. 500 operating hours, but after not more than one year: Check When the motor is running The electrical parameters are maintained.

In an explosive atmosphere, dust can ignite and an explosion occur. This can result in death, serious injury or material damage. * Do not open the motor in an explosive and dusty atmosphere when it is still at normal operating temperature. * Allow the machine to cool down before opening it. 9.2.9.3 Insulation resistance and polarization index Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: Before starting up a machine for the first time After an extended period in storage or downtime Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: Is the winding head insulation conductively contaminated? Has the winding insulation absorbed moisture? As such, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: Can the machine be put into operation? Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: "Testing the insulation resistance and polarization index" (Page 84) 1MB155 / 1MB555 SH 71 ... 355 114 Operating Instructions, 12/2018, A5E41926185A Maintenance 9.2 Inspection and maintenance 9.2.9.4 Regreasing intervals and types of grease for operating rolling-contact bearings Regreasing intervals The regreasing intervals for rolling bearings in operating hours and the grease types are stated on the machine's lubricant plate. Regardless of the actual number of operating hours reached, regrease the motor at least once a year. The lubrication information can be found on the lubricant plate. Note Observe the regreasing intervals for the rolling bearings The regreasing intervals for rolling bearings are different from the service/inspection intervals for the machine. Failure to regrease the rolling bearings at the specified intervals can result in bearing damage. Regreasing The spent grease chamber is designed to accommodate the spent grease for a computed, rated service life of 20000 operating hours. Clean the grease nipples before regreasing and then gradually press in an appropriate type and amount of grease, as described on the lubricant plate. The shaft must rotate so that the new grease can be distributed in the rolling bearing. The rolling bearing temperature rises sharply at first, then drops to the normal value again after the excess grease has been displaced out of the bearing. - If the machine is fitted with grease collection chambers : Unbolt the grease collection chambers at the intervals shown on the notice plate with the motor stopped, and remove the used bearing grease. When doing this, you avoid that the grease backs up and the bearings overheat. WARNING Rotor can fall out If the machine is in a vertical position, the rotor can fall out while work is being performed on the locating bearing. This can result in death, serious injury or material damage. Support or relieve the rotor when carrying out work with the machine in a vertical position. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 115 Maintenance 9.2 Inspection and maintenance Grease types For the standard operating range, a grease for temperatures down to -20 C is normally used for the initial greasing of rolling bearings. If the machine has been ordered for use in the extended temperature range of below -20 C, the permissible type of grease is indicated on the lubricant plate. Note Grease quantity control Only use the specified greases so that the grease quantity control operates perfectly. The data on the motor lubricant plate is decisive. Note Carefully note that it is not permissible to mix different grease types. 9.2.9.5 Cleaning Cleaning the grease ducts and spent grease chambers The spent grease collects outside each bearing in the spent grease chamber of the outer bearing cap. When replacing bearings, remove the spent grease. Dismantle the bearing cartridges to replace the grease in the lubrication duct. Cleaning the cooling air ducts Regularly clean the cooling air ducts through which the ambient air flows. The frequency of the cleaning intervals depends on the local degree of fouling. Damage to the machine when cleaning with compressed air or water jets Do not direct compressed air or water jets in the direction of the shaft outlet or machine openings. Avoid direct impact of compressed air and water jets on sealing elements of the machine.

This can result in an explosion during operation in a potentially explosive atmosphere. This can result in death, serious injury, or material damage. * Use only original spare parts for explosion-proof machines, including components, such as seals, terminals, cables, and cable entries. If you have any questions, please contact the service center (Page 145). * Commercially available equivalent standard parts such as screws and bolts may be used. 10.4 Ordering spare parts via the Internet You can use "Spares on Web" to determine the order numbers for motor spare parts quickly and easily. Spares on Web (https://www.sow.siemens.com/?lang=en). 10.5 Replacing rolling bearings Rolling bearings When ordering rolling bearings, in addition to the bearing identification code, the supplementary specifying code is also necessary for the bearing version. Both of these codes are stamped on the lubricant plate and specified in the motor documentation, or can also be taken from the installed bearings. Always replace the rolling bearings with the identical bearings. If insulated rolling bearings are fitted, use insulated rolling bearings of the same type as spare parts. This will prevent any bearing damage being caused by bearing currents. 1MB155 / 1MB555 SH 71 ... 355 126 Operating Instructions, 12/2018, A5E41926185A Spare Parts 10.6 Anti-condensation heating 10.6 Anti-condensation heating WARNING Explosion hazard due to improper maintenance If repairs to the anti-condensation heating are not carried out correctly, e.g. if unauthorized or untested spare parts are used, this can result in explosions during operation in a potentially explosive gaseous atmosphere. This can result in death, serious injury, or material damage. * Repairing and mounting the anti-condensation heating and the subsequent routine testing must always be undertaken by experts from the service center (Page 145), because this work requires extensive specialist knowledge. * Only authorized and tested spare parts may be used. 10.7 Parts groups definition A distinction is made between the following groups of parts: Spare parts Spare parts are machine parts that can be ordered during the production time - and for a further 5 years after discontinuation of production. These parts should only be replaced by authorized service or modification partners. Repair parts Repair parts are machine parts that can be supplied during the active production of the machine (until the product discontinuation). Repair parts are parts used for the repair or modification of the current products. These parts should be replaced only by authorized service or modification partners. Standardized parts Standardized parts are machine parts obtained from free trade outlets in accordance with their necessary dimensions, materials and surface finish. A detailed list can be found in the "Standardized parts" section. Other parts Other parts are small parts required to complete the exploded drawing. However, these parts cannot be supplied as individual spare or repair parts. The delivery in assembly units (e.g. complete terminal box) is possible on request. 1MB155 / 1MB555 SH 71 ... 355 Operating Instructions, 12/2018, A5E41926185A 127 Spare Parts 10.8 Ordering example The following supply commitments apply to replacement machines and repair parts following delivery of the motor: For up to 3 years after the delivery of the original machine, in the event of total machine failure, Siemens will supply a comparable replacement machine with regard to the mounting dimensions and functions; it is possible that this will involve a new series. If a replacement machine is supplied within the 3 year period, this does not mean that the warranty restarts. Replacement machines delivered after the active production of the machine series are also identified as spare motors on the rating plate. Spare parts are offered only for these spare motors on request; repair and replacement are not possible. After a period of 3 years (after the delivery of the original machine), it is only possible to repair these machines (depending on the availability of the spare parts required). For up to 5 years after the delivery of the original motor, spare parts will be available and for a further 5 years, Siemens will provide information about spare parts and will supply documents when required. 10.8 Ordering example Table 10- 1 Ordering example End shield, drive end 1.40 End shield Machine type * 1MB1553-1EB43-4AB4 Ident: No. * UD 1504/156750601 * corresponding to the rating plate Take the type and serial number from the rating plate and the machine documentation. When replacing rolling bearings, in addition to the bearing identification code, the replacement code for the bearing version is required. Both of these codes are specified on the rating plate and in the machine documentation. They are also shown on the installed bearings. The graphical representations in this chapter show schematic diagrams of the basic versions. They are used for spare part definitions.
