Bind the power cables in a bundle. Route the external power
cables and ground cable through the upper cable tray.
Particularly, connect the ground cable to the ground bolt at the
top of the cabinet; thread the external power cables into the
cabinet through the cable holes and connect them to the DC
input terminals on the DC PDU at the top of the cabinet.
Put the cord end terminal on the RTN(+) or NEG(-) input
terminal on the PDU with the fluted side facing outward. Then
tighten the screws.
If copper fittings have been installed in the power input areas,
put the cord end terminal of each BGND cable on the RTN(+)
input terminal on the PDU with the fluted side facing outward.
Then tighten the screws.
Put the two-hole OT terminal of each blue -48 V power cable on
the NEG(-) input terminal on the PDU with the protruding side
facing outward.
