WARNING
Electrical shock hazard
Every movement of the rotor compared with the stator and vice versa induces a voltage at the
stator power connections.
When the motor is switched on, the stator power connections are also at a specic voltage.
If you use defective cable ports, you could suer an electric shock.
• Only mount and remove the electrical components if you are qualied to do so.
• Any work carried out at the motor must always be done with the system in a no-voltage
condition.
• Do not touch the cable ports. Correctly connect the stator power connections, or insulate
them properly.
• Do not disconnect the power connections when the stator is under voltage (live).
• Only use the specic power cables intended for the purpose.
• First connect the protective conductor (PE).
• Connect the cable shield through a wide area.
• First connect the power cable to the stator before you connect the power cable to the
inverter.
• First disconnect the connection to the inverter before you disconnect the power connection
to the stator.
• Disconnect the protective conductor PE last.
WARNING
Risk of electric shock as a result of residual voltages
There is a risk of electric shock if hazardous residual voltages are present at the motor
connections. Even after switching o the power supply, active motor parts can have a charge
exceeding 60 μC. In addition, even after withdrawing the connector 1 s after switching o the
voltage, more than 60V can be present at the free cable ends.
• Wait for the discharge time to elapse.
WARNING
Risk of injury when carrying out disassembly work
Risk of death, serious personal injury and/or material damage when carrying out disassembly
work.
• When disassembling, observe the information in Chapter "Decommissioning".
The motors have been designed for a long service life. Carefully ensure that maintenance work
is correctly performed, e.g. removing chips and particles from the air gap.
