of the Wiring Unit are enclosed loosely.
Proceed as follows:
1. Mount the Wiring Unit to the Drive Unit.
2. Mount the Wiring Unit (with mounted Drive Unit) to the terminal box flange with
the supplied seal and the original screws. Earthing is achieved by means of forced
contact.
3. Install the mains connection cable and, if required, additional cables for the external
brake resistor and/or motor holding brake.
4. Wire the mains connection, the brake resistor and/or motor holding brake (if
required) to the plug connector. The PE conductor of the mains cable must be
connected to one of the earthing connectors +in the Drive Unit.
– For an installation of the controller conforming to standards, the second earth
connection + can be used for an additional equipotential bonding.
5. Plug the plug connectors of the Wiring Unit onto the Drive Unit.
