CONNECTION AND START-UP 4.1 Connecting the mechanical system CAUTION Cutting and crushing hazard when removing the device from the packaging Blades can be bent Carefully remove the device from its packaging, only touching the wall ring. Make sure to avoid any shock. Wear safety shoes and cut-resistant safety gloves. ; Check the device for transport damage. Damaged devices must no longer be installed. Earth wire contact resistance in accordance with EN 60335 Compliance with the impedance specifications in accordance with EN 60335 for the protective earth circuit must be verified in the end application. Depending on the installation situation, it may be necessary to install an additional protective earthing conductor via the additional protective earth connection point available on the device. 4.2.2 Voltage control With open loop speed control using transformers or electronic voltage regulators (e.g. phase angle control), excessive current may occur. In addition, noises can occur with phase angle control depending on the mounting situation. ; Install the undamaged device according to your application. 4.2 Connecting the electrical system DANGER Electric voltage on the device Electric shock Always install a protective earth first. 4.2.3 Frequency inverter Please use a frequency converter only after consultation with ebm-papst. Fit sinusoidal filters that work on all poles (live-live and liveearth) between the frequency inverter and the motor for operation with frequency inverters. Depending on how the device is installed, noises may occur. Check the protective earth. DANGER Incorrect insulation Risk of fatal injury from electric shock Use only cables that meet the specified installation requirements for voltage, current, insulation material, load etc. Route cables such that they cannot be touched by any rotating parts. 4.3 Connection of the cables CAUTION Electrical voltage The fan is a built-in component and features no electrically isolating switch. ; First connect the "PE" (protective earth) connection. Only connect the fan to circuits that can be switched off with an all-pole separating switch. When working on the fan, you must switch off the installation/machine in which the fan is installed and secure it from being switched on again. Translation of the original operating instructions Heating of the motor due to use of a frequency converter must be checked in the application by the customer. NOTE Water penetration into leads or wires Water enters at the cable end on the customers side and can damage the device. Make sure that the cable end is connected in a dry environment. Connect the device only to circuits that can be switched off using an all-pole disconnecting switch. 4.2.1 Prerequisites ; Check whether the data on the type plate agree with the connection data. ; Before connecting the device, ensure that the supply voltage matches the operating voltage of the device. ; Only use cables designed for current according to the type plate. For determining the cross-section, follow the basic principles in accordance with EN 61800-5-1. The protective earth must have a cross-section equal to or greater than the outer conductor crosssection. External leads are brought out of device. Connect the lines according to your application. When doing so, observe chapter 4.4 Connection screen. 4.3.1 Motor protection CAUTION Voltage The device is a built-in component with no isolating switch. Connect the device to a suitable tripping device. Only connect the device to circuits which can be deenergised with an all-pole disconnection switch. When working on the device, the system/machine in which the device is installed must be secured so as to prevent it from being switched back on. NOTE Lack of motor protection Without motor protection, the motor can overheat and suffer damage. Connect up the thermal overload protector installed in the coil. The motors are equipped with thermal overload protectors to protect the devices. Check to make sure that the thermal overload protector is correctly connected before each operation. Failure to connect up the thermal overload protector correctly will invalidate your warranty claim.

This also applies for devices which have already been equipped with plugs and terminals or similar connectors by the customer. WARNING Hot motor housing Fire hazard Ensure that no combustible or flammable materials are located close to the fan. ; Inspect the device for visible external damage and the proper function of the protective features before switching it on. ; Check the air flow paths of the fan for foreign objects and remove any that are found. ; Apply the nominal voltage to the voltage supply. 4.7 Switching off the device ; Disconnect the device from the supply voltage at the main switch for the supply line. Translation of the original operating instructions ; When disconnecting, be sure to disconnect the earth wire connection last. 5. MAINTENANCE, MALFUNCTIONS, POSSIBLE CAUSES AND REMEDIES Do not perform any repairs on your device. Return the device to ebmpapst for repair or replacement. WARNING Terminals and connections have voltage even with a unit that is shut off Electric shock Wait five minutes after disconnecting the voltage at all poles before opening the device. CAUTION The motor restarts automatically when operating voltage is applied, e.g. after a power failure. Danger of injury Keep out of the danger zone of the device. When working on the device, switch off the mains supply voltage and secure the latter from being switched on again. Wait until the device stops. Insert the brought-out thermal overload protector into the control circuit so that the cooled off motor does not switch on independently after a fault. If the device remains out of use for some time, e.g. when in storage, we recommend switching the device on for at least two hours to allow any condensate to evaporate and to move the bearings. Malfunction/error Impeller running roughly Possible cause Imbalance in rotating parts Motor does not turn Mechanical blockage Mains supply voltage faulty Faulty connection Thermal overload protector responded Unacceptable operating point Possible remedy Clean the device; if imbalance is still evident after cleaning, replace the device. If you have attached any weight clips during cleaning, make sure to remove them afterwards. Switch off, deenergise, and remove mechanical blockage. Check mains supply voltage, restore power supply. De-energise, correct connection, see connection diagram. Allow motor to cool off, locate and rectify cause of error, if necessary cancel restart lock-out Check operating point Item no. 13683-5-9970 * Revision 81525 * Release 2014-05-12 * Page 8 / 9 ebm-papst Mulfingen GmbH & Co.
