It is the responsibility of the installation engineer or operator/ owner of the device to ensure, if necessary after consultation with the network operator, that this device is only connected to a connection point with a Ssc value that is greater than or equal to 120 times the rated output of the arrangement. 4. CONNECTION AND STARTUP 4.1 Mechanical connection WARNING Hot motor housing Risk of fire → Ensure that no combustible or flammable materials are located close to the motor. CAUTION Cutting and crushing hazard when removing motor from packaging → Carefully remove the device from its packaging. Strictly avoid shocks. → Wear safety shoes and cut-resistant safety gloves. CAUTION Heavy load when unpacking device Risk of physical injury, such as back injuries. Translation of the original operating instructions → Two people should work together to remove the device from its packaging. ; Check the device for transport damage. Damaged devices are not to be installed. ; Install the undamaged device in accordance with your application. CAUTION Possible damage to the device If the device slips during installation, serious damage can result. → Ensure that the device is securely positioned at its place of installation until all fastening screws have been tightened. 4.2 Electrical connection DANGER Voltage on the device Electric shock → Always connect a protective earth first. DANGER Faulty insulation Risk of fatal injury from electric shock → Use only cables that meet the specified installation regulations for voltage, current, insulation material, capacity, etc. → Route cables so that they cannot be touched by any rotating parts. DANGER Electrical charge (>50 µC) between phase conductor and protective earth connection after switching off supply with multiple devices connected in parallel. Electric shock, risk of injury → Ensure sufficient protection against accidental contact. Before working on the electrical hookup, short the supply and PE connections. CAUTION Voltage The motor is a built-in component and has no disconnecting switch. → Only connect the motor to circuits that can be switched off with an all-pole disconnection switch. → When working on the motor, secure the system/machine in which the motor is installed so as to prevent it from being switched back on. NOTE Device malfunctions possible Route the device's control lines separately from the supply line. → Maintain the greatest possible clearance. Recommendation: clearance > 10 cm (separate cable routing) NOTE Water ingress into wires or cables Water ingress at the customer end of the cable can damage the device. → Make sure the end of the cable is connected in a dry environment. Only connect the device to circuits that can be switched off with an all-pole disconnection switch. 4.2.1 Requirements ; Check whether the data on the nameplate match the connection data. ; Before connecting the device, make sure the power supply matches the device voltage. ; Only use cables designed for the current level indicated on the nameplate. For determining the cross-section, note the sizing criteria according to EN 61800-5-1. The protective earth must have a cross-section equal to or greater than that of the phase conductor. We recommend the use of 105 °C cables. Ensure that the minimum cable cross-section is at least AWG 26 / 0.13 mm². → Check the protective earth.

Depending on the circumstances of installation, it may be necessary to connect an additional protective earth conductor to the extra protective earth terminal on the device. The protective earth terminal is on the housing and has a ground conductor symbol and a bore hole. 4.2.6 Locked-rotor protection 4.2.2 Supply connection and fuses 4.3 Connection in terminal box Assignment of supply cable cross-sections and their required fuses (line protection only, no equipment protection). 4.3.1 Preparing cables for connection Nominal voltage Only strip the cable as far as necessary, ensuring that the cable gland is sealed and there is no strain on the connections. For tightening torques, see Chapter 3.1 Product drawing. 3/PE AC 380-480 VAC 3/PE AC 380-480 VAC 3/PE AC 380-480 VAC 3/PE AC 380-480 VAC Fuse VDE 16 A UL 15 A Automatic circuit breaker VDE C16A Cable crosssection mm² 1.5 Cable crosssection *AWG 16 20 A 20 A C20A 2.5 14 25 A 25 A C25A 4.0 12 32 A 30 A C32A 6.0 10 For asymmetrical power systems or if a phase fails, the leakage current can increase to a multiple of the nominal value. Due to the locked-rotor protection, the starting current (LRA) is equal to or less than the nominal current (FLA). NOTE Tightness and strain relief are dependent on the cable used. → This must be checked by the user. * AWG = American Wire Gauge 4.2.3 Reactive currents Translation of the original operating instructions Because of the EMC filter integrated for compliance with EMC limits (interference emission and immunity to interference), reactive currents can be measured in the supply line even when the motor is at a standstill and the line voltage is switched on. ● The values are typically less than 250 mA. ● At the same time, the effective power in this operating state (operational readiness) is typically < 5 W. 4.2.4 Residual current circuit breaker (RCCB) Only universal residual current devices (type B or B+) are allowed. As with variable frequency drives, residual current devices cannot provide personal safety while operating the device. When the device's power supply is switched on, pulsed charging currents from the capacitors in the integrated EMC filter can lead to the residual current devices tripping without delay. We recommend the use of residual current circuit breakers with a trip threshold of 300 mA and delayed tripping (super-resistant, characteristic K). Fig. 1: Recommended stripped lengths in mm (inside terminal box) Legend: CL = control lines 4.3.2 Connecting wires to terminals WARNING Live terminals and connections even with device switched off Electric shock → Wait five minutes after disconnecting the voltage at all poles before opening the device. ; Remove the cap from the cable gland. Only remove caps where cables are fed in. ; Equip the cable glands with the seals provided in the terminal box. ; Route the wire(s) (not included in scope of delivery) into the terminal box. ; First connect the "PE" (protective earth). ; Connect the wires to the corresponding terminals. Use a screwdriver to do so. When connecting, ensure that no wire ends fan out. Item no. 50851-5-9970 · ENU · Change 89187 · Approved 2016-04-16 · Page 7 / 12 ebm-papst Mulfingen GmbH & Co.
