Pre-Charge Connections on Drives with DC Input
You must connect the ASIC board connectors X9 and X15 to the X50
terminal block for the pre-charge circuit. The X50 terminal block is located
on the Control Frame in the left-hand enclosure. Refer to
for the location of these connection points. Refer to publication
