7.1.8 Installing the contactor
X
Ensure that the contact surfaces on the mounting
plate (3) or frame and the bottom of the contac-
tor are free from dirt and other contamination (e.g.
metal chips).
X
Position the contactor (1) on the mounting plate/
frame (3) which is provided with mounting holes.
X
Screw the contactor (1) on the mounting flange
to the mounting plate/frame (3) using mounting
screws (2) according to the table below.
-
In designs with the mounting holes imple-
mented as threaded holes, screw the mounting
screws into the holes directly, not forgetting the
suitable screw locking elements.
-
In designs with through holes, fit the mounting
screws and suitable screw locking elements (on
both sides) and tighten the screws using nuts.
X
Tighten the mounting screws to the specified
torque, which depends on the strength class (min.
