The cable glands must be provided by the customer because Ex-protected cable glands are not included in the scope of supply. * Seal unused threads with an Ex-certified screw plug. This gives the required IP degree of protection. Observe requirements in accordance with EN 60079-14 when selecting connection cables. Note Requirements for cables The temperature resistance of the connection cables must be at least 80 C. Plasticinsulated, flexible cables must have the same resistivity as heavy-duty, rubber-insulated cables. SIEMENS MOTION-CONNECT power and signal cables meet these requirements. Please note that the surface of the motor gets hot during operation. Make sure that the connection cables do not touch any hot surfaces when routing the cables. Use twist-protected cable entries with strain relief for cables that are not permanently fixed. Observe the degree of protection of the motors when fitting cable entries. Select connection cables taking into account the rated current and the system-specific conditions such as ambient temperature, installation method etc. in accordance with IEC / EN 60364-5-52 and IEC / EN 60204-1. Use EMC cable glands for permanently installed cable entries. Use shielded cables whose shields are conductively connected to a large area of the terminal box of the motor using EMC cable glands. Make sure that the cable shields are properly connected. Arrange the exposed connecting cables in the terminal box so that the PE conductor has an excess length and the insulation of the cable conductors cannot be damaged. Only remove insulation from the cable ends so that the insulation reaches up to the cable lug, terminal, or wire end ferrule. Adapt the size of the cable lugs or end sleeves in line with the dimensions of the terminal board connections and the cross-section of the power cable (use parallel connecting cables, if necessary). Make sure that the inside of the terminal box or connector is clean and free of cable cuttings and moisture. Tighten all of the screws for the electrical connections (terminal board connections, with the exception of the terminal strips) to the specified torque: 1PH8 main motors explosion-proof version for zone 2 and 22 (option M03 and M39) Operating Instructions, 11/2018, A5E44794151B AA 53 Connection 5.2 Electrical connection Table 5- 1 Tightening torques Thread M4 M5 M6 M8 M10 Tightening torque in Nm 0.8 ... 1.2 1.8 ... 2.5 2.7 ... 4 5.5 ... 8 9 ... 13 When connecting or changing internal connection cables, always observe the minimum air clearance of 5.5 mm. Avoid protruding cable ends. Check seals and sealing surfaces of the terminal box or connector to ensure that the degree of protection is maintained. Take measures to ensure that connecting cables cannot rotate, are not subject to strain and pushing force and also provide anti-kink protection. It is not permissible to subject the connector to continuous force. The coding slot for the plug-in connections must be aligned when inserted into the socket connector. The union nut must be tightened by hand up to the endstop. Plug in or remove the connector only when the system is de-energized.

Remove this fault immediately. WARNING Danger to life when the insulation is damaged as a result of the high-voltage test The motor insulation can be damaged when a motor high voltage test is carried out. You can get an electric shock when touching live components. Further, electronic components can be destroyed. The components involved include temperature sensors and encoders, for example. * Do not carry out a high-voltage test on the motor. WARNING Danger to life when the cooling system bursts The motor will overheat if it is operated without cooling. When cooling water enters the hot motor, this immediately and suddenly generates hot steam that escapes under high pressure. This can cause the cooling water system to burst, resulting in death, severe injury and material damage. * Never operate the motor without cooling. * Only commission the cooling water circuit when the motor is in a cool condition. 1PH8 main motors explosion-proof version for zone 2 and 22 (option M03 and M39) Operating Instructions, 11/2018, A5E44794151B AA 63 Commissioning 6.2 Checklists for commissioning WARNING Danger to life when the forced ventilation draws in hair and articles of clothing There is a danger of being drawn into the machine (by means of hair, ties, loose articles of clothing, etc.) at the air intake. * Remove any ties or similar. * Wear a hat or hair net to prevent hair from being drawn in. * Keep the air intake area free of any loose objects. * Take the appropriate protective measures to prevent hair and articles of clothing from being drawn in.

For motors that were stored, were the storage conditions according to the "Storage" section and the bearing replacement intervals according to the "Bearing replacement intervals" section complied with? 1PH8 main motors explosion-proof version for zone 2 and 22 (option M03 and M39) Operating Instructions, 11/2018, A5E44794151B AA 67 Commissioning 6.3 Checking the insulation resistance 6.3 Checking the insulation resistance After long storage or shutdown periods, the insulation resistance of the windings must be measured to ground with direct voltage. WARNING Danger to life through electric shock During and immediately after the measurement, the terminals are in some cases at hazardous voltages, which can lead to death when touched. * Only check the insulation resistance if you are appropriately qualified to do this. * Before measuring the insulation resistance, read the manual for the insulation resistance meter you are going to use. * Never touch the terminals when making measurements or immediately after the measurement. * Check the connected supply feeder cables to ensure that the line supply voltage cannot be connected. Always measure the insulation resistance of the winding to the motor enclosure when the winding temperature is between 20C and 30C. When performing the measurement, wait until the final resistance value is reached (this takes approx. one minute). Limits The table below specifies the measuring circuit voltage as well as the limit values for the minimum insulation resistance and the critical insulation resistance with a rated motor voltage of UN < 2 kV: Table 6- 7 Stator winding insulation resistance at 25 C Rated voltage UN < 2 kV Measurement voltage 500 V (at least 100 V) Minimum insulation resistance with new, cleaned, or repaired windings 10 M Critical specific insulation resistance after a long operating time 0.5 M/kV Note the following: Dry, new windings have an insulation resistance of between 100 M and 2000 M (sometimes higher). If the insulation resistance is close to the minimum value, this could be due to humidity and/or an accumulation of dirt. The insulation resistance of the motor winding can drop during the course of its service life can drop due to ambient and operational influences. The critical insulation resistance for a temperature of 25 C on the winding can be calculated by multiplying the rated voltage (kV) by the specific critical resistance value (0.5 M/kV); Example: Critical resistance for a rated voltage (VN) of 0.6 kV: 0.6 kV x 0.5 M/kV = 0.3 M 1PH8 main motors explosion-proof version for zone 2 and 22 (option M03 and M39) 68 Operating Instructions, 11/2018, A5E44794151B AA Commissioning 6.4 Switching on and switching off Note Cleaning and/or drying the windings when reaching critical insulation resistance If the critical insulation resistance is less than or equal to this value, the windings must be dried or, if the fan is removed, cleaned thoroughly and dried. Note that the insulation resistance of dried, clean windings is lower than that of warm windings. The insulation resistance can only be evaluated accurately when measured on a winding that has been cooled down to room temperature (approx. 20C to 30C). Note Measured value close to critical value If the measured value is close to the critical value, the insulation resistance should be subsequently checked at suitably regular intervals. Values apply for measurement at a winding temperature of 25 C. 6.4 Switching on and switching off Note EMERGENCY OFF To avoid accidents, inform yourself about the EMERGENCY OFF function before you switch on the system. The motor is switched on and off using the inverter. Read about this topic in the inverter operating instructions. Before switching on Ensure that the inverter is correctly parameterized.
