The supply power must have over voltage and low voltage protection equipment. Make sure no
phase disorder (L1 to R, L2 to S, L3 to T). Suppose phase disordered, system can’t be started, and no
display in controller.
Drain electricity protection switch is needed for the system. No drain electricity protection switch
may cause electrical shock.
