Re-install the CU board or the adaption board in the electronics box as
follows:
♦ Insert the CU board into mounting position 1 and the adaption board
into mounting position 2 or 3.
Mounting position 3 cannot be used until at least one adaption board
has been installed at mounting position 2. Boards should first be
installed in mounting position 2, before mounting position 3 is used.
♦ Secure the CU board/adaption board at the handles with the fixing
screws.
Re-connect the previously removed connections.
Check that all the connecting cables and the shield sit properly and are
in the correct position.
