Q : How to solve the problem while report phase-loss fault?
A: The inverter can be divided into single-phase 220V and three-phase 380V(or 400V, 460V), and the input phase loss only exists in three-phase products. The main circuit of inverter, R, S and T are three-phase AC input. When one of the phases is disconnected due to the fault of fuse or circuit breaker, phase-loss failure occurs. Please check the power input cable is normal or not.
