Wiring example
Note (Wiring diagram)(H2) = Feedback circuitF1 = Electronic fuseRelay 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.The example shows a 2-channel control of 2 muting sensors and an external master reset button.The wiring diagram is shown with non-actuated muting sensors and in de-energised condition.
