The CU can be extended with accessories before being mounted. Additional cable glands
or M12 connectors for further input and output signals can be mounted.
How to proceed:
1. Turn the hinged socket connector into an upright position.
2. In order to protect the CU electronics from damage, it must be unhooked and
separated from the CU frame.
3. Open the prepared bushings as required. Use a suitable tool, e.g. a big screwdriver or
step drill, to remove the areas from inside out. If required, plane rough edges.
4. Insert a connector M12 or cable gland with seal and screw down.
5. Position the CU frame onto the DU aufsetzen. The CU can be rotated by 180° in
order that the position of the cable outlets meets the local requirements in an
optimal way.
6. Insert the CU electronics and let it snap into place.
7. Wire the additional signals.
8. Turn the hinged socket connector towards the CU and carefully insert it into the
counter plug.
9. If a fieldbus is used, where address and transmission speed can be set, they must be
set right now since later settings are only possible after dismounting the cover.
10. Mount the cover of the Drive Unit to the CU with four screws (5.0 Nm/44 lb−in).
The mounting of the CU is now completed mechanically and electrically.

If all previous steps have been executed and completed, the DU can be mounted.
How to proceed:
1. Position the DU in parallel to the WU and CU without twisting it. The four fixing
screws show the correct position if they are put through the locating holes of the CU
into the threads of the WU.
2. The connectors are contacted with light pressure and the DU has reached the final
position.
3. Tighten the four fixing screws (5.0 Nm/44 lb−in)
The installation is completed.
