4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by autho-
rised personnel in a de-energised condition.
The contact labelling can be found in the wiring compartment of the
switch. Cable glands (included in delivery) are only authorised for per-
manent cables. The constructor must provide for the necessary strain
relief. After wiring, dust and soiling must be removed from the wiring
compartment.
4.2 Contact variants
Contacts are shown with safety guard closed.

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
- The installation is executed according to the instructions
- The connection is executed correctly
- The cable is correctly executed and connected
- Check the free movement of the actuating element
- The safety component is not damaged
- Remove particles of dust and soiling
- Check cable entry and connections in de-energised condition
- Check for correct installation of the hinge safety switch
- Check the positive link between the shaft and the door hinge
5.2 Maintenance
In case of correct installation in accordance with the instructions
described above, the component requires little maintenance. For use in
extreme conditions, we recommend routine maintenance including the
following steps:
1. Check for correct installation of the hinge safety switch
2. Lubricate the shaft or plunger
3. Remove particles of dust and soiling
4. Check cable entry and connections in a de-energised condition
Do not open the device when live.
Adequate measures must be taken to ensure protection
against tampering either to prevent tampering of the safety
guard, for instance by means of replacement actuators.
Damaged or defective components must be replaced.
For explosion protection reasons, the component must be ex-
changed after max. 1 million operations.
6. Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised condi-
tion only.
6.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
