munication module is connected to the housing of the
AC31 basic unit by a snap-fit connection. The electrical
connection is via a 40-pole ribbon cable with socket con-
nector, soldered onto the 07 KP 90 R303 side.
Mounting the expansion housing
1. Detach the cover on basic unit 07 KT 94 from the net-
working interface.
2. Plug the socket strip of the 40-pole ribbon cable se-
cured to the 07 KP 90 R303 onto the networking con-
nector of the 07 KT 94.
3. Place both units on a level surface and slide them to-
gether so that they engage.
4. Slide in the connection part to fix the housing in posi-
tion.
Note: Mounting of the 07 KP 90 R303 to 07 KR 91 /
07 KT 92 / 07 KT 93 takes place in a similar way.
