Main Circuit Terminals
Note: Confirm the following when wiring models CIMR-A 4A0930 and 4A1200:
Remove the jumpers shorting terminals R/L1-R1/L11, S/L2-S1/L21, and T/L3-T1/L31 when operating with 12-phase
rectification. Refer to the Technical Manual for more information.
When operating without 12-phase rectification, properly wire terminals R1/L11, S1/L21, and T1/L31 in addition to terminals
R1/L1, S1/L2, and T1/L3.
