u Main Circuit Connection Diagram
Refer to Figure 5 , Figure 6 , and Figure 7 when wiring the main circuit of the drive. Connections may vary based on drive
capacity.
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.
