Main Circuit Connection Diagram

Refer to diagrams in this section 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: Route motor leads U/T1, V/T2 and W/T3 separate from all other leads to reduce possible interference and noise related issues.
Failure to comply may result in abnormal operation of drive and nearby equipment.
