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.
NOTICE
Destruction of the motor
Removing the connection block for the motor feeder cables at the motor can destroy the motor.
• Never remove the connection block on the motor for the motor feeder cables (power and
The cables for the power connection are brought out at the front of the stator (B
flange). The open cable ends must be connected in a terminal box, which must be
provided by the machine manufacturer. Sufficient installation space must be provided
