When using separate power supplies for the control circuit and the main circuit
Cable size for the control circuit power supply (terminals R1/L11 and S1/L21)
●
Terminal screw size: M4
●
Cable gauge: 0.75 mm² to 2 mm²
●
Tightening torque: 1.5 Nm
Connection method
When a fault occurs, opening of the electromagnetic contactor (MC) on the inverter power supply
side results in power loss in the control circuit, disabling the fault output signal retention. Terminals
R1/L11 and S1/L21 are provided to hold a fault signal. In this case, connect the power supply terminals
R1/L11 and S1/L21 of the control circuit to the input side of the MC.
Do not connect the power cable to incorrect terminals. Doing so may damage the inverter.
