EMR 2
Technical Data
9.3
Plug assignments
The 25-pole plugs of the EMR 2 control unit are mechanically coded (different part numbers). Because of
the different pins, the vehicle plugs (F) or the plant plugs (F) and engine plug (M) only into the sockets provi-
ded for them, so that incorrect plugging in is impossible.
