Terminal Name Description
Main
circuit
R, S, T Power input
Terminals for power supply phase, power voltage detection and control power input. Connect
to commercial power supply. Running the inverter without connecting these terminals will
damage the high power factor converter (FR-HC).
R4, S4, T4 Power input Connect to reactor 2.
P, N Inverter connection Connect to P and N terminals of inverter.
Control ciruit
Input signals
MC1,CMC2 MC connection Connect to MC1, MC2 in external box.
RES Reset
