Procedure
1.  Insert the actuating or signaling element (A) from the front through the mounting opening 
of the front plate (B). 
2.  Fit the holder (C) from behind (wiring side) onto the actuating or signaling element and 
lock it into place. 
3.  The unit must be aligned before it is finally tightened and secured against twisting (see 
Chapter Alignment (Page 97)). 
4.  Turn the screw at the holder until the actuating or signaling element is fixed securely and 
cannot vibrate or twist (tightening torque 1.0 to 1.2 Nm). 
5.  Snap the contact module(s) (D) from behind onto the holder. To do this, hold the modules 
so that they are tilted downward slightly and place them onto the holder  
from behind and then press them upwards until you feel the module latch in the holder. 
Single- or two-pole contact modules can be mounted on the holder. 
The modules can be stacked (max. 2 modules behind one another). 
6.  Mount an LED module (E), if necessary. You can mount the LED module on the holder 
only in position 3/6 (center position).
