Main Circuit Connection Diagram

Refer to Figure 3.2 when wiring the main circuit of the drive. The 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: When installing an optional DC Reactor, remove the jumper between main circuit terminals +1 and +2.
