4.
To review the wiring and termination requirements, see paragraph A.3 on
page A−31.
5.
Route the PDU input cables from the AC source through either the top or bottom
of the cabinet to the PDU input terminals on the main input breaker CB1. See
Figure A-29, Figure A-30, Figure A-31, or Figure A-32 starting on page A−46 for
wiring access and terminal locations. See paragraph A.4 on page A−39 for conduit
landing plate locations.
Top Access Wiring.
Remove the top conduit plate from the top of the PDU.
Identify all conduit requirements and mark their location. Drill and punch all
conduit holes in the top conduit plate prior to mounting on the PDU. Install the
conduit plate and install all conduit runs into the plate. Pull the wiring through the
conduit into the wiring area.
Bottom Access Wiring.
Remove the bottom conduit plate from the inside bottom
of the PDU. Identify all conduit requirements and mark their location. Drill and
punch all conduit holes in the bottom conduit plate prior to mounting on the PDU.
Install the conduit plate and install all conduit runs into the plate. Pull the wiring
through the conduit into the wiring area.
6.
Connect phase A, B, and C, and, if required, Neutral power wiring between the
AC source and the PDU input terminals. See Table K through Table N on
pages A−35 through A−38 for termination requirements.
7.
Ground the PDU according to local and/or national electrical wiring codes by
routing and connecting the ground wire to the input ground lug. See Figure A-29,
Figure A-30, Figure A-31, or Figure A-32 starting on page A−46 for PDU terminal
locations.
8.
If wiring a PDU with only subfeed breakers, proceed to Step 12; if wiring a PDU
with distribution panels or a distribution panel and subfeed breakers, proceed to
Step 9.
9.
Install customer−supplied branch circuit breakers (Cutler-Hammer bolt-on type
BAB or QBHW breakers for bolt−on panels, or plug-on type HQP or QPHW
breakers for plug−on panels) into the distribution panel (see Figure A-29,
Figure A-30, or Figure A-31 starting on page A−46).
NOTE
When wiring branch circuits, begin adding conduits at the back of the center conduit landing plate to
simplify future circuit additions.
10.
Route output cables to the branch circuit breakers and wire the branch circuits
according to the branch circuit breaker manufacturer’s ratings and instructions,
and national and local electrical codes (input is prewired to the panelboard). See
Table N on page A−38 for termination requirements.
If the optional Powerware Energy Management System Level 3 (EMS Level 3)
branch circuit monitoring (BCM) is installed, route branch wiring through the
current transformer (CT) opposite the breaker terminal to the breaker lug (see
Figure 3-2). Use care when bending and routing the wires through the CTs.
