3.4.3 Precautions for Wiring Main Circuit Power Input
At the time of shipment, short-circuit bus bars are provided between R/L1 and R1/L11, S/L2 and S1/L21,
and between T/L3 and T1/L31 on the main circuit power input terminal. Remove these short-circuit bus bars
when applying 12-phase rectification.
