6. Set-up and maintenance
6.1 Functional testing
The safety function of the safety-monitoring module must be tested.
The following conditions must be previously checked and met:
1. Correct fixing
2. Check the integrity of the cable entry and connections
3. Check the safety-monitoring module's enclosure for damage.
4. Check the electrical function of the connected sensors and their
influence on the safety-monitoring module and the downstream
actuators
6.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:
1. Check the correct fixing of the safety-monitoring module
2. Check the cable for damages
3. Check electrical function
The device has to be integrated into the periodic check-ups
according to the Ordinance on Industrial Safety and Health,
however at least 1x/year.
Damaged or defective components must be replaced.
7. Disassembly and disposal
7.1 Disassembly
The safety-monitoring module must be disassembled in a de-energised
condition only.
Push up the bottom of the enclosure and hang out slightly tilted
forwards.
7.2 Disposal
The safety-monitoring module must be disposed of in an appropriate
manner in accordance with the national prescriptions and legislations.

8.1 Wiring examples
The application examples shown are suggestions. They however do not
release the user from carefully checking whether the switchgear and its
set-up are suitable for the individual application.
The wiring diagram is shown with guard doors closed and in a
de-energised condition. Inductive loads (e.g. contactors, relays, etc.)
are to be provided with suitable interference suppression circuitry.
