Note (General)	Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.

Note (Wiring diagram)	The wiring diagram is shown with guard doors closed and in de-energised condition. Relay outputs: Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts. The control recognises cross-short, cable break and earth leakages in the monitoring circuit. 2 channel control shown for a guard-door monitor with two contacts, of which at least one contact has positive break, with external reset button (R).
