The mounting holes can either be
-
threaded holes (for threaded screws)
-
or through holes (for threaded screws and nuts).

The length of the fixing screws has to be deter-
mined according to the constructional conditions.

In order to secure the mounting screws against
self-loosening, appropriate screw locking ele-
ments have to be provided. Schaltbau strongly
recommends Schnorr-Washers (or similar) to se-
cure the screws.

As an alternative, contactors of the C193 series can
also be installed by means of DIN rail mounting.
