Preparatory measures
X
A suitable mounting plate with 4 mounting holes
in accordance with the following dimensional
drawings (
Fig. 1 and Fig. 2
) must be provided for
fastening of the contactors.
X
The mounting holes can be either:
-
threaded holes (for threaded screws)
-
or through holes (for threaded screws and nuts)
X
Fastening of the contactors on the mounting plate
is performed using four M5 mounting screws.
-
The length of the mounting screws must be de-
termined dependent on the structural circum-
stances.
-
To secure the mounting screws so that they
do not come loose, appropriate screw locking
elements must be provided. Schaltbau recom-
mends using Schnorr washers (or similar).
-
The mounting screws must be equipped with
washers (resting on the device). Installation
without washers is not permitted!
-
The mounting screws must be tightened to a
torque of 2.3 ... 2.7 Nm (screws of strength class
4.6).
