3. Mounting
3.1 General mounting instructions
The mounting dimensions are mentioned at the rear of the enclosure.
Fit the hinge safety switch so that the shaft of the hinge safety switch
is aligned with the pin of the door hinge. Use the supplied tamperproof
safety screws to fix the hinge safety switch. To set the switching point,
first adjust the plug/shaft connection by means of a threaded pin. Then
establish the positive link between the shaft and the door hinge. To that
effect, use the offset arranged mounting holes and the supplied spiral
clamping pin. The switch enclosure must not be used as end stop. Any
mounting position. The head can be turned by 4 x 90°. Loosen the four
screws of the head by means of a Torx screwdriver (T 20), turn the
head in the desired position and retighten the screws.

The contact labelling can be found in the wiring compartment of the
switch. For the cable entry, suitable cable glands with an appropriate
degree of protection must be used. Non-used input openings must be
sealed by means of threaded plugs. After wiring, dust and soiling must
be removed from the wiring compartment.
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
According to IEC 60204-1, the versions with connector
must only be used in PELV circuits.

2. Check for correct installation of the hinge safety switch
3. Check the switch enclosure for damage
4. Check the integrity of the cable entry and connections
5.2 Maintenance
In case of correct installation in accordance with the instructions
described above, the component requires little maintenance.
A regular visual inspection and functional test, including the following
steps, is recommended:
1. Check the positive link between the shaft and the door hinge
2. Check for correct installation of the hinge safety switch
3. Remove particles of dust and soiling
4. Check cable entry and connections
Damaged or defective components must be replaced.
6. Disassembly and disposal
