Safety Relay

4. Proper use

The switching unit can only fulfil its safety-related task if used properly.
The switching unit is intended to be used as protection in combination with safety contact mats, safety bumpers
and safety contact edges with 8.2 kΩ resistor for standby-current monitoring.
Any uses above and beyond these uses constitute improper use. The manufacturer assumes no liability for
damages arising from improper use.
The device may only be used in special applications with the manufacturer's express consent.

5. Application examples
