Connecting the Power Module to the motor
Depending on the operating environment, different cable length limits are required for the
connection between the power module and motor. Unshielded cables up to 100 meters in
length are possible in industrial electrical networks.
Wiring the Power Module
• Connect the phases and the earth conductor to the pluggable terminal clamps U2, V2, W2, and PE.

• Connect the PE connection.
• Insert the cables from the power module through the opening of the terminal box
• Slide the phases in accordance with the phase assignment in the connections.
• Screw the cover back onto the motor.
The motor and Power Module are now connected together. Before continuing the commission-
ing of the motor and inverter, ensure that the motor and the inverter are isolated from the
line supply.
