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 control panel thickness of approximately 3 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 in a plate that 
is > 3 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 87641PZD1 or flat-
head DIN ISO 2380-1 A/B 1 x 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.
