 12-Phase Rectification
 Removing the Jumper
Models CIMR-A4A0930 and 4A1200 are compatible for operation with 12-phase rectification. Operation with
12-phase rectification requires the user to separately prepare a 3-winding transformer for the power supply. Contact
YASKAWA or your nearest sales representative for the transformer specifications.
Notes on wiring are listed below.
WARNING! Fire Hazard. Failure to remove jumpers shorting the power supply terminals on the main circuit when operating with
12-phase rectification may cause death or serious injury by fire.
 Application Notes
• Remove M5 screws and then jumpers to operate with 12-phase rectification as shown in Figure 3.2.
•Models CIMR-A4A0930 and 4A1200 are shipped from the factory with jumpers short-circuiting terminals 
R/L1-R1/L11, S/L2-S1/L21, and T/L3-T1/L31.
