The flexible actuator can only be inserted
frontally.
The rigid actuator can be inserted fron‐
tally and laterally.

Measures against accidental damage
You can use the following measures to avoid unintentional damage to the safety switch:
•
Select the mounting location so that the safety switch is protected from impacts
and mechanical pressure.
•
Fit an additional stop for the door. The safety switch must not be used as a stop.
4.3.4
Measures against manipulation
The safety switch must not be defeated (contacts jumpered), rotated away, removed, or
rendered ineffective in any other way. You must put measures in place, if necessary, to
reduce the possibilities for circumventing the device.
4.3.5
Preparing the mounting surface
Overview
If the safety locking device is used without mounting brackets, appropriate holes must
be provided in the mounting surface. The necessary drill holes can be seen from the
dimensional drawings of the safety switch.
For variants with escape release, the maximum wall thickness must be taken into
account.
Maximum wall thickness
It must be possible to reset the escape release after actuation. The button of the
escape release must therefore not lie flat after actuation. The wall thickness of the
mounting surface must therefore be max. 34 mm.
Using spacers, the axis of the escape release can be extended in 30 mm increments.
This enables the maximum wall thickness to be increased to 64 mm or 94 mm.
