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 specific voltage.
If you use defective cable ports, you could suffer an electric shock.
• Only mount and remove the electrical components if you are qualified 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 specific 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.
