Replacing Pre-installed Copper Fittings
c
Do not install any copper fitting in the power output areas of the DC PDU. If copper fittings are required, install
them only in the power input areas of the DC PDU.

Position a four-in-one copper fitting to the NEG(-) input terminals, and secure it by tightening the screws.
Connect external power cables (blue) to the NEG(-) input terminals and BGND cables (black) to RTN(+) input
terminals.
Free the two-in-one copper fittings from the NEG(-) input terminals
on the circuit breakers on the PDU and then remove them.

The blue power cables connecting to the NEG(-) terminals must use two-hole OT terminals and the BGND
cables (black) connecting to the RTN(+) terminals must use cord end terminals.
CAUTION
Both NEG(-) and RTN(+) terminal pairs must be connected or disconnected.
By default two-in-one copper fittings have been installed on NEG(-) and RTN(+)
terminals of the PDU before the delivery. Based on the site survey result,
determine whether the two-in-one copper fittings pre-installed on NEG(-) terminals
need to be replaced with four-in-one copper fittings and whether additional four-in-
one copper fittings need to be installed on the RTN(+) terminals in the middle of the
PDU.

Install a four-in-one copper fitting on the RTN(+) input terminals in the middle of the PDU, covering the RTN(+)
A2 and RTN(+) A3 terminal pair, and the RTN(+) B2 and RTN(+) B3 terminal pair.
