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 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 0.8 to 1.0 Nm).
5. Snap the PCB carrier (D) from behind onto the holder. To do this, hold the PCB carrier so
that it is tilted downwards slightly and place it onto the holder from behind
and then press it upwards until you feel the PCB carrier latch in the holder.
6. Equip the printed-circuit board (F) with the components.
7. Screw the PCB securely onto the PCB carrier.
Note
Number of PCB carriers
Make sure there is sufficient stability. Use several PCB carriers if necessary.
