8.  Compare the settings of the two electronics modules. Set the 

adjustment elements of the new electronics module to the same 

setting of the old one.

Information:

Make sure that the housing is not rotated during the electronics ex-

change. Otherwise the plug may be in a different position later.
9.  Insert the electronics module carefully. Make sure that the plug is 

in the correct position.

10.  Screw in and tighten the two holding screws with a screwdriver 

(Torx size T10 or Phillips 4)

11.  Insert the wire ends into the open terminals according to the wir-

ing plan

12.  Press down the opening levers of the terminals, you will hear the 

terminal spring closing

13.  Check the hold of the wires in the terminals by lightly pulling on 

them

14.  Check cable gland on tightness. The seal ring must completely 

encircle the cable.

15.  Screw the housing lid back on
The electronics exchange is now finished.
