Line reactors/commutating reactors reduce the proportion of low-frequency harmonics on the line, thereby improving the power factor. Line reactors/commutating reactors avoid mutual interference caused by low-frequency noise and protect the converter input. The capacitive DC link of frequency converters is protected. SIDAC RFI suppression filters SIDAC RFI suppression filters have the following properties: SIDAC RFI suppression filters are installed upstream of the three-phase DC drive or three-phase AC drive. RFI suppression filters avoid mutual interference caused by high-frequency interference currents. SIDAC output reactors and sine-wave filters SIDAC output reactors and sine-wave filters have the following properties: SIDAC output reactors and sine-wave filters are installed downstream of the three-phase AC drive (frequency converter). SIDAC output reactors and sine-wave filters increase the service life of the motor and improve system reliability. SIDAC smoothing reactors SIDAC smoothing reactors have the following properties: SIDAC smoothing reactors are used in the load circuit of DC drives. SIDAC smoothing reactors reduce the harmonic content for the DC motor as well as the rate of current rise, thereby enabling the use of DC high-speed circuit breakers. 8 RFI suppression filter System Manual, 12/2007, HBF 05-002-02-1B TTProduct lineTT 2.2 TTDevice descriptionTT 2.2 Device description T T Device versions RFI suppression filters are available in single-phase and three-phase versions. Each device is assigned to a converter requiring radio-interference suppression in respect of the line. Most devices are equipped with finger-safe terminals and these filters offer IP20 degree of protection. All filters with flat connectors are designed for IP00 degree of protection. Application RFI suppression filters are installed in the line-side supply, upstream of a converter. AC currents with the mains frequency as the fundamental frequency flow through them. EMC regulations Compliance with EMC regulations must be ensured in individual cases by means of an application-specific measurement. The converter's rating data must be taken into account when selecting a filter. Capacitor discharge The filters feature built-in discharge resistors so that the energy stored in the capacitors can be quickly reduced, thereby ensuring that the voltage at the terminals drops to within permissible levels. However, before carrying out any work on the filter, check that it is safely isolated from the supply.

Line reactors To benefit from an additional reduction in phase effects on the system, combine the RFI suppression filter with a SIDAC line reactor/commutating reactor. SIDAC output reactors/sine-wave filters To ensure optimum operation of the RFI suppression filter, a motor-cable length of 50 m is recommended as the absolute maximum. When using an RFI suppression filter, the maximum possible motor-cable length can be increased by using SIDAC output reactors or sine-wave filters. Application-specific measurement is required Ensure compliance with EMC regulations in individual cases by means of an applicationspecific measurement. This measurement must be requested and ordered separately. The converter's rating data must be taken into account when selecting a filter.

Rules 1 to 13 apply on a general level. Rules 14 to 20 are particular important for limiting emitted interference. General rules Rule 1 Ensure that all metal parts of the control cabinet are surface-connected with good conductivity (not paint on paint). If necessary, use contact washers or serrated lock washers. When connecting the control-cabinet door to the control cabinet, use bonding strips that are as short as possible (also see Rule 20). Suitable line/commutating reactors are recommended as a means of counteracting lowfrequency phase effects on the system and protecting the converter. You must install these between the line connection and the RFI suppression filter inside a metal cabinet. Ensure that the control-cabinet configuration, system configuration and wiring are carried out in compliance with the rules of EMC-compliant configuration. On the line side, route the grounding to the motor via the reactor, filter and converter. 4EF15 TN L1 L1' L2 L2' L3 L3' M 3~ Figure 5-2 Mounting on mounting plate 1 TN system 2 Line reactor 3 Supply system 4 Load 5 Frequency converter 6 Shielded motor cable 7 Metal mounting plate RFI suppression filter System Manual, 12/2007, HBF 05-002-02-1B 17 TTOperation planningTT 5.4 TTEMC-compliant configuration of drive systemsTT Grounding systems/machines and grounding drives The grounding of systems/machines is a protective measure. In the case of drives, grounding affects emitted interference and interference immunity. System grounding can be carried out point-to-point or two-dimensionally. For drives, select two-dimensional grounding, i.e. all the parts of the system that need to be grounded are connected two-dimensionally or as a mesh. - The motor must be connected using a shielded cable. - Unshielded motor cables must only be used in conjunction with a sine-wave filter. - The shield must be applied to the surface of the motor and converter. Figure 5-3 Shield connection of motor cables inside control cabinet 1 Connect to cabinet enclosure on both sides ensuring good conductivity and maximum contact area 2 Shielding bus 3 Cable propping bar Rule 2 When laying the signal cables and power cables, ensure that sufficient space is left between them (minimum distance: 20 cm). Avoid data links Provide separators between electric power cables and signal cables. Ensure multiple grounding of separators Rule 3 Connect contactors, relays, solenoid valves, electromechanical hours counters, etc., inside control cabinet using interference suppression combination, e.g. RC elements, diodes, varistors. Install the protective circuit directly on the relevant coil. 18 RFI suppression filter System Manual, 12/2007, HBF 05-002-02-1B TTOperation planningTT 5.4 TTEMC-compliant configuration of drive systemsTT Rule 4 Twist unshielded cables from the same electric circuit (go and return conductors) or ensure that the surface area between the go and return conductors is as small as possible to avoid unnecessary frame antennae. Rule 5 Avoid unnecessarily long cables Thus coupling capacities and coupling inductivities are kept small. Rule 6 Ground spare cores at both ends. This achieves an additional shielding effect. Rule 7 Lay cables close to grounded plates to reduce interference injection. You should not, therefore, route wiring and spare cables randomly within the cabinet; instead, keep them close to the cabinet enclosure/mounting plates. Rule 8 Use a shielded cable to connect tachometers, encoders and resolvers. Connect the shield to the tachometer, encoder or resolver and to the converter, ensuring maximum contact area. The shield must not be broken at any point, e.g. by intermediate terminals. Rule 9 Ground the shields of digital signal cables on both sides (sender and receiver), ensuring maximum contact area and good conductivity. In the event of poor equipotential bonding between the shield connections, run an additional equalizing conductor with a cross-section of at least 10 mm parallel to the shield for the purpose of reducing the shield current. Multiple grounding of the shields (= connection to cabinet enclosure) is possible. Multiple grounding of the shields is even possible outside the control cabinet. Foil shields are at least 5 times less effective than braided shields. Rule 10 Ground the shields of analog signal cables with good equipotential bonding on both sides. Good equipotential bonding is achieved if Rule 1 is followed. If low-frequency interference occurs on the analog lines, e.g.: Speed/measured value fluctuations as a result of equalizing currents (hum) then connect the analog signal shield to the signal sink on one side, e.g. analog input of the converter. Ground the other side of the shield via a capacitor (e.g. 10 nF/100 V Type MKT). The use of the capacitor means that the shield is connected for high frequencies on both sides.

Ensure that there is a separate power supply for each converter. Rule 13 Avoid interference injection via the line connection. Connect the converter and PLCs/control electronics to different line supplies. If only one common line supply is available, isolate the PLCs/control electronics from the line supply by means of an isolating transformer. 20 RFI suppression filter System Manual, 12/2007, HBF 05-002-02-1B TTOperation planningTT 5.4 TTEMC-compliant configuration of drive systemsTT Rules for limiting emitted interference Rule 14 An RFI suppression filter must be used to ensure compliance with limit class A or B (EN 55011) even in cases where sine-wave filters or dv/dt filters have been installed between the motor and the converter. The issue of whether an additional filter is required for further loads depends on the controller used and how the rest of the control cabinet is wired. Rule 15 Ensure that the RFI suppression filter is located in the vicinity of the source. Ensure that the filter is surface-connected to the control-cabinet enclosure, mounting plate, etc. A bright, metallic mounting plate is preferable (e.g. stainless steel, galvanized steel), since the entire contact surface establishes the electrical contact. If a painted mounting plate is used, the screw positions for mounting the frequency converter and and RFI suppression filter must be paint-free to ensure electrical contact with the mounting plate. Physically separate the input and output cables of the RFI suppression filter. Rule 16 Use shielded cables to connect all variable-speed motors in order to limit emitted interference. Connect both sides of the shields to the relevant enclosures in a manner that ensures low inductance (short and maximum possible contact area). Shield the motor cables inside the control cabinet or shield them by means of grounded separators. Suitable motor cables include, for example, Siemens PROTOFLEX-EMV-CY (4 x 1.5 mm ... 4 x 120 mm) with Cu shield. Cables with steel shields are not suitable. Use a suitable screwed joint with shield contact on the motor for the shield connection. Make sure that there is a low-impedance connection between the motor terminal box and motor housing. If necessary, use an additional flexible grounding wire. The motor terminal box must not be made of plastic. 1 Motor terminal box 2 Metric/heavy-gauge threaded joint Shield connection on motor RFI suppression filter System Manual, 12/2007, HBF 05-002-02-1B 21 TTOperation planningTT 5.4 TTEMC-compliant configuration of drive systemsTT Rule 17 Install a line reactor between the RFI suppression filter and the line supply. Rule 18 Physically separate the power supply cable and motor cables, e.g. by using grounded separators. Rule 19 The shield between the motor and converter must not be broken at any point as a result of integrating components such as output reactors, sine-wave filters, dv/dt filters, fuses and contactors. Assemble the components on a mounting plate, which will simultaneously serve as the shield connection for the incoming and outgoing motor cables. It may be necessary to use grounded separators for the purpose of shielding the components. Rule 20 To limit interference radiation (particularly in the case of limit class B), all cables connected to the control cabinet from the outside must be shielded in addition to the power supply cable. When mounting inside a cabinet, install the RFI suppression filter (and if necessary a reactor) in the direct vicinity of the converter. When laying cables, keep them as short as possible. When connecting the power supply cable to the RFI suppression filter (or reactor), ensure that it is kept separate from other cables so that no interference can be injected into the interference-suppressed power supply cable that would partially cancel out the effects of the RFI suppression filter. Connect the housing of the converter and RFI suppression filter with low resistance for high-frequency interference currents. This can be achieved by placing the converter and RFI suppression filter on the same mounting plate. Ensure that the converter and RFI suppression filter are surface-connected to this mounting plate. The best solution here is to use a bare metal mounting plate (e.g. made of stainless steel or galvanized sheetsteel), since the total contact surface establishes the electrical contact. If a painted mounting plate is used, the screw positions for the converter and RFI suppression filter must be paint-free to ensure electrical contact with the mounting plate. 22 RFI suppression filter System Manual, 12/2007, HBF 05-002-02-1B Assembly T 6.1 6 T Assembly T T Assembly/Installation Install the RFI suppression filter on a bare metal plate. Proceed as follows to install the RFI suppression filter inside a control cabinet: Install the RFI suppression filter (and reactor, if required) directly upstream of or next to the converter. When laying cables, keep them as short as possible. When connecting the power supply cable to the RFI suppression filter (or reactor), ensure that it is kept separate from other cables so that no interference can be injected into the interference-suppressed power supply cable that would partially cancel out the effects of the RFI suppression filter.

The basic rules for the EMC-compliant configuration of drive systems are outlined in the previous section. Mounting and interference suppression RFI suppression filters feature a metallic housing. The 4 screws used for screw mounting ensure: Mechanical fastening That the RFI suppression filter is shielded by means of a generous contact-area connection to the reference ground. High-frequency interference currents The housing of the converter and RFI suppression filter must be connected with low resistance for high-frequency interference currents. To achieve this, proceed as follows: Install the converter and RFI suppression filter on a single bare metal mounting plate (stainless steel or galvanized sheet-steel). The total contact surface establishes the electrical contact. If a painted mounting plate is used, ensure that the screw positions for the converter and RFI suppression filter are paint-free so that electrical contact with the mounting plate can be ensured. Note Shielded cable for motor connection If an output filter is not used in conjunction with a frequency converter, the motor must be connected by means of a shielded cable. Ensure that the shield makes full surface contact with the motor and converter. 26 RFI suppression filter System Manual, 12/2007, HBF 05-002-02-1B 7 Connection T 7.1 T Prerequisites and definitions T T Use in TN systems RFI suppression filters must only be used in TN systems (grounded neutral point).
