4 Installing Power Cables Between the DPD63-8-8 PDU and PDF
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.
NOTE
DANGER
Four-in-one copper
fitting (left or right)
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.
Four-in-one copper
fitting (middle)
Position a four-in-one copper fitting to the NEG(-) input
terminals, and secure it by tightening the screws.
Free the two-in-one copper fittings from the NEG(-) input
terminals on the circuit breakers on the PDU and then
remove them.
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.

The blue power cables connecting to the NEG(-) terminals must use two-hole

must use cord end terminals.
