1) Loosen the upper screws.
2) Remove the lower screws.
3) Remove the jumper
4) Connect the separate
power supply cable for the
control circuit to the lower
terminals (R1/L11, S1/L21).
When the protected circuit is activated, opening of the electromagnetic
contactor (MC) on the inverter power supply side results in power loss in
the control circuit, disabling the alarm output signal retention. Terminals
Inverter
R1/L11 and S1/L21 are provided to hold an alarm signal. In this case,
connect the power supply terminals R1/L11 and S1/L21 of the control
circuit to the primary side of the MC.
