Horizontal mounting position
Vertical mounting position 1
Vertical mounting position 2
In most cases, the contactors are mounted on mounting plates or mounting
frames. They must be solid enough to carry the weight of the contactors un-
der the shock and vibration conditions of the railway environment.
The contactors (Lower Module) are fixed with 4 or more mounting screws,
depending on the number of poles. The screws (and if applicable the nuts)
must be steel grade 8.8. Schaltbau strongly recommends Schnorr-Washers
(or similar) to secure the screws. The screws must be tightened with the rat-
ed torque permissible for the screws and the nuts.

sure that both Upper and Lower Module are for horizontal
mounting.
CT1000 contactors for vertical mounting must only be mount-
ed vertically (Lock bars are red, position is also shown on the
