3. Mounting
3.1 General mounting instructions
During fitting of the actuator and the sensor, the requirements
of ISO 14119, especially paragraph 7 must be observed!
Four mounting holes are provided for fixing the switch. When used in
applications with function for the protection of man, the components
must be fitted so that disassembly is prevented (e.g. drill out the hexag-
onal recess of the fixing screws, blocking the hexagonal recess using a
plastic cone diamater 5.1 mm). The hinge switch furthermore must be
pinned after assembly and adjustment (Fig. 1). The hinge safety switch
must not be used as an end stop. Any mounting position. The mounting
position however is chosen so that the components are preferably fitted
in the upper part of the safety guard to avoid the ingress of dirt and soil-
ing as well as damage to the components. In case of painting activities,
the components must be covered. The supplied fixing material must
be used. We recommend that the fixing screws are painted after the
component is fitted.

4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition. For the
cable entry, only suitable cable glands and for the connector
suitable plugs with an appropriate degree of protection must
be used.
1. Open the enclosure cover of the hinge switch.
2. Connect the wires and cables. For flexible leads, conductor ferrules
must be used. In the area of the metal thread at the cable input in the
wiring compartment, the supplied protective tube (shrink tube) must
be used.
3. After the switch has been fitted, the switching function and the open-
ing angle of the safety guard must be checked. The switching angle
of the NC contacts set in factory is approximately 3°. Caution: for the
TESF.../U version, the following paragraph "Special instructions for
the on-site setting" imperatively must be observed!
4. Follow the steps below to put back the enclosure cover:
– Firmly push the enclosure cover under an angle of approx. 30°
onto the retaining collar (Fig. 2) and simultaneously exercise a
downwards pressure (Fig. 3).
– Uniformly tighten the 3 cover screws (Fig. 4) with 0.6 Nm tighten-
ing torque.
– The contact labelling can be found in the wiring compartment of
the switch.
