◆ Main Circuit Connection Diagram
Refer to the Figure 9 when wiring the main circuit of the drive. Connections may vary based on drive capacity. The DC
power supply for the main circuit also provides power to the control circuit.
NOTICE: Do not use the negative DC bus terminal “-” as a ground terminal. This terminal is at high DC voltage potential. Improper
wiring connections could damage the drive.
NOTICE: Equipment Hazard. Separate motor and/or braking circuit wiring (terminals, U/T1, V/T2, W/T3, +3, +2, +1,(-), B1, B2, from all
other wiring. Place motor wiring within its own conduit or cable tray with appropriate divider, and use shielded motor cable where
appropriate. Improper wiring practices could result in malfunction of drive due to electrical interference.
