Main Circuit Configurations

Refer to the Table 3.1 when wiring the drive's main circuit. 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.
