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 R1/L11
Inverter
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.
