Power Wiring

1.
If not already removed, remove left front solid panel and right front vented
panel from the Powerware 9330 (10 kVA---20 kVA) UPS cabinet or left front
solid panel and front vented panels from the Powerware 9330 (25 kVA---40
kVA) UPS cabinet. Front panels are secured with magnetic latches and are
removed by pulling panels straight forward to disengage magnetic latches (see
Figure 2---1 or 2---5).
2.
Remove screws securing internal safety shield panels and remove panels to
gain access to input and output terminals.
NOTE: Remove UPS cabinet input, output, and remote battery input conduit landing
plate to punch conduit holes.
3.
If wiring an optional remote battery system, proceed to step 4; otherwise
proceed to step 6.
CAUTION:
When sizing battery system, do not exceed internal battery charger
capabilities. Refer to Chapter 15 "Specifications", for maximum battery charger
currents.
4.
Route battery cables from the remote battery system to UPS Remote Battery
Terminal Block. Refer to Appendix A of this manual for wiring access
information.
5.
Connect positive, negative, and ground DC power wiring from external battery
system to the Remote Battery Terminal Block and ground terminals in the UPS
cabinet. Refer to Appendix A of this manual for wiring and termination
requirements and wiring access information.
6.
Route input and output cables through wireway to the UPS terminal blocks.
Refer to Appendix A of this manual for wiring access information.
7.
If wiring a single feed system, proceed to step 8; if wiring a dual feed system,
proceed to step 10.
CAUTION:
Proper UPS operation requires a Bypass Input Neutral connection. This neutral
is required to be the common conductor between all bypass source phases
(e.g., "wye" or "4 wire" source).
8.
Connect phase A, B, C, and Neutral input power wiring from source to the
Bypass Input Terminal Block and Neutral Terminal Block in the UPS cabinet.
Refer to Appendix A of this manual for wiring and termination requirements and
wiring access information. Note wiring connections for single feed systems.
9.
Proceed to step 17.
10.
If wiring a 10 kVA---20 kVA UPS dual feed system, proceed to step 11; if wiring
a 25 kVA---40 kVA UPS dual feed system, proceed to step 14.
11.
Disconnect single feed jumpers from phase A, B, and C terminals on Input
Breaker CB1 and Bypass Input Terminal Block. Remove jumpers from cabinet.
