Electrical connection

NOTICE
Destruction of the motor if it is directly connected to the three-phase line supply
The motor will be destroyed if it is directly connected to the three-phase line supply.
• Only operate the motors with the appropriately configured converters.
Risk of electric shock due to incorrect connection
If you incorrectly connect the motor this can result in death, serious injury, or extensive
material damage. The motors require an impressed sinusoidal current.
• Connect the motor in accordance with the circuit diagram provided in this documentation.
• Refer also to the documentation for the drive system used.
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 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
• Do not touch the cable ports. Correctly connect the stator power connections, or insulate
• 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
• First disconnect the connection to the inverter before you disconnect the power connection
• Disconnect the protective conductor PE last.
