Holders
The holders are used to secure the actuating or signaling elements and the contact module
or LED module. The holders are designed for mounting in front plates with a plate thickness
of 1 to 6 mm.
When delivered, the holders are set to a front plate thickness of approximately 4.5 mm. They
are placed in the
↑ arrow direction from the rear onto the actuating and signaling elements.
The fastening screw is located at the top. If they are to be mounted on a front plate that is >
4.5 mm thick, you must adjust the fastening screw of the holder before you install the holder.
Note
Note the maximum permissible front plate thickness!
When label holders, protective caps or similar accessories are used, it is important to
remember that the maximum permissible front plate thickness must be reduced by the plate
thickness of the relevant accessory.
Tool
For securing, we recommend a size 2 screwdriver (cross-tip DIN ISO 87641PZ1 or flat-head
DIN ISO 2380-1 A/B 1x 4.5). The tightening torque is 1.0 to 1.2 Nm.
Grounding of the front plate
If you mount a metal actuator on a metal front plate using a metal holder, the actuator is
grounded via the tip of the fastening screw. This enables grounding via the connection on
the front plate.
If the metal holder is to be used several times, grounding via the grounding stud is
recommended!
