2If 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.

a.Connect the red wires – BAT 0, – BAT 1, – BAT 2, and – BAT 3.

b.Connect the black wires + BATRTN 0, + BATRTN 1, + BATRTN 2, and + BATRTN 3.

c.Connect the remaining LRTN wire (orange or white wire).

Note: If a junction box is used, the connections described in Steps 2 through 4 apply to the junction box rather than the pedestal.

3Connect the red BAT (–48 V) wires.

a.At the 8B/2R or 8B/4R master power cabinet, connect wires to the terminals on the –ve distribution rail (see Figure 46 on page 128).

b.At the PDU, connect the wires to the terminal block.
