    Wiring Diagram

    AC DC voltage monitoring relay wiring diagram

    Note:
    1. Relay contacts position shown in "Power-on" (Healthy) condition. If power is off or any fault occurs, the relay contacts will be opposite to the diagram.
    2. For DC power, the polarities must be correctly connected. Otherwise, the relay doesn't work.
