7 Secure the 1200 W DC PSU in the power supply bay by pushing down on the locking handle until it
clicks in place.
NOTE
The DC PSU does not energize until the locking handle latches.
CAUTION
When you route the DC cable harnesses, minimize stress on the cables. It is important to route each of the
outermost cables out the opposite side of installation to maximize the bend radius and to avoid stress on the cables.
For example, you should route the leftmost cable harness across the switch so that it exits through the right side of
the grate. Route the rightmost cable harness across the switch so that it exits through the left side of the grate. The
four middle cables can route in either direction.
8 Energize the DC circuit for the 1200 W DC PSU.
To install additional 1200 W DC PSUs, repeat steps 2 through 8.
