Removing the Jumper
Models 4A0930 and 4A1200 are compatible for operation with 12-pulse rectification. Operation with 12-pulse rectification
requires the user to separately prepare a 3-winding transformer for the power supply. Contact Yaskawa or your nearest sales
representative for transformer specifications.
WARNING! Fire Hazard. Failure to remove jumpers shorting the power supply terminals on the main circuit when operating with 12-pulse
rectification may cause death or serious injury by fire.

Application Notes
Models 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.
Remove M5 screws and jumpers as shown in Figure 3.7 to operate with 12-pulse rectification.
