Safety Relay

English

For the design of the safety system to conform to engineer standards acc. to EN

ISO 13849-1:2015 category 2, the safety system must be tested prior to each

dangerous movement of the plant / machine. Without tesng, the operaon or

wiring of the ELMON relay 31 safety relay does not sasfy these safety requirements.

The manufacturer assumes no liability in the event of non-observance or intenonal abuse.
