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.
Correct mounting positions
The contactors are designed for horizontal or vertical
mounting positions
-
horizontal: main contacts (1) must point upwards
-
vertical: plasma exits (2) must point upwards
Examples for intended mounting positions are shown
in
Fig. 18/(A)
Not permissible are suspended or inverted mounting
position as shown in
Fig. 18/(B)
