Installation
1. Cut out an opening in the cover plate.
Refer to the operating instructions for the correct cutout dimensions.
2. Insert the escutcheon into the cutout from the front and fasten by means of small spring
steel sheets at the rear of the cover plate.
The fastening system is designed such that the the escutcheon can move in the cutout. In
other words, the escutcheon is "float-mounted". Tolerance compensation by around ± 3 mm
is thus afforded in the horizontal direction and by as much as ± 6 mm in the vertical direction.
This tolerance compensation is necessary in order to achieve the small gap dimensions of
max. ± 0.5 mm between the escutcheon and the unit on the one hand and, on the other, to
compensate tolerances in the cubicle, for example, which are always intrinsic to the cubicle
design.
Typical tolerance compensation examples are:
● Tolerance compensation of the door angle with right-hinged or left-hinged doors
● Tilting of devices under their own weight when they are fastened to thin mounting plates
