Why Should The Three-phase Terminals Be Connected To The Live Wire?

2000 kva stabilizer Forms an independent regulating circuit according to phases. L1, L2, and L3 of the power grid must be connected to the corresponding terminals and the phase sequence must be maintained so that 20kva servo stabilizer can independently sample and compensate the voltage of each phase. In a three-phase four-wire system, the neutral (N) and ground (PE) wires of 20kva servo stabilizer single phase are connected separately according to the terminals. The phase correspondence between input and output must not be confused. The wiring label is the basis for verification. Incorrect wiring will cause the control module to malfunction or the protection to trip.
