Electrical connection

Risk of electric shock
There is a risk of electric shock if you incorrectly establish an electrical connection.
• Only work on the electrical connection if you are appropriately qualified to do so.
• Carry out all work at the motor with the system in a no-voltage condition.
• Connect the motor according to the circuit diagram provided.
• In the motor terminal box, ensure that the connecting cables are connected so that there
• Ensure that the terminal box is tight and sealed.
Electric shock as a result of defective connecting cables
Using defective connecting cables can result in an electric shock. Further, material damage
can occur, e.g. as a result of fire.
• When installing the motor, make sure that the connecting cables
• Maintain the permissible bending radii.
• Do not use the cables to hold the motor.
• Do not pull on the motor cables.
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 off the power supply, active motor parts can have a
charge exceeding 60 μC. In addition, even after withdrawing the connector 1 s after
switching off the voltage, more than 60 V can be present at the free cable ends.
• Wait for the discharge time to elapse.
Danger to life due to electric shock
As a result of the permanent magnets in the rotor, when the motors rotate a voltage is
induced. If you use defective cable ports, you could suffer an electric shock.
• Do not touch the cable ports.
• Connect the motor cable ports correctly, or insulate them properly.
