• B5 is used in spec ial cases only
Coding:
( ... ) In brackets is stated
the corresponding coding
designation for the
control wiring plug (1 0.2)
The coding pins can
befitted in the
control wiring socket (1 0.1)
and/or in the
control wiring plug. (10.2)
Basic design:
Number of sockets optional,
but always with the
basic assignment:
1,8, 10, 20, 21, 31, 33, 40.
Sockets and pins can be
mixed In the control wiring
socket (1 0.1) and control
wiring plug (1 0.2) as required
