Connecting power to the NT7D67CB PDU
To connect the external power system to the PDU, use the following
procedure for each column (this procedure gives the connections for a
four-module column).
Note: All wiring to the PDU must be routed within the cable-tie saddles
and under the cable restraint bar at the base of the pedestal.
1
If a junction box is used, insert the conduit from the junction box into one
of the conduit access holes in the pedestal.
Connect the wires from the junction box to the matching connections on
the terminal block on the PDU:
Connect the red wires to BAT 0,1 and BAT 2,3.
Connect the black wires to BATRTN 0,1 and BATRTN 2,3.
Connect the remaining wire (orange or white) to LRTN.
Note: If a junction box is used, the connections described in steps 2
through 4 apply to the junction box rather than the PDU.
2
Connect the red BAT (–48 V) wires:
At the power plant:
For an NT6D82, connect the wires to the first two circuit breakers
in the main control/distribution panel (see Figure 157).
For a QBL12 or QCA13, connect the wires to the first two
available 30-amp fuse output connections on the –48 V terminal
panel (see Figure 158).
Note: Each 30-amp fuse output has two connection points on the
distribution panel. Only one 30-amp connection point is required for
every two modules; typically, #6 AWG is adequate (#4 AWG can be
used).
For a QBL15, connect the wires to terminals 1, 2, 3, or 4
(DISCHARGE) on TB1 (see Figure 159).
