Powerware 9315 Parallel Capacity/Redundant System with PHP SSBM
164201373 Rev. A
092402
NOTE:
Two tables in Appendix A cover the cables running from the UPM output
terminals to the SSBM module input terminals E8 (
∅
A), E9 (
∅
B), E10 (
∅
C),
and E4 (Neutral)
Table O covers the recommended wiring and conduit sizing based on the
applicable Powerware 9315 Installation manual provided with the UPM. Using
the noted power wiring, Table O shows the number of UPMs that can be
connected to each SSBM model. This number of UPMs is limited by the number
of cables connections for the SSBM module input terminals E8, E9, E10, and
E4 shown in Table C in Appendix A.
If the parallel capacity/redundant system requires the connection of more
UPMs to the SSBM than is shown in Table O, refer to Table P. Table P covers
the recommended wiring and conduit sizing to support connection of the
maximum number of UPMs (up to eight) for each SSBM model.
CAUTION:
The UPM output wiring configurations in Table O in Appendix A do not match
that shown in the applicable Powerware 9315 UPS Installation manual. Review
the planned UPM output power cables to ensure the planned cabling is
compatible with the available number of cable connections at both the UPM
and SSBM terminals.
Powerware UPMs are rated for operation in a
40
_
C
room ambient. For this
reason, Table O and P are based on the entire 3
∅
/ 3W system being housed
in a
40
_
C
room ambient, the use of
90
_
C
copper wire and a 0.80 derating factor
because there are more than three current carrying conductors in a raceway
(NEC Table 310---16 and Notes).
Refer to the applicable Powerware 9315 Installation manual provided with the
UPM for all other UPM power cable requirements (AC input, DC input, and
grounding)
NOTE:
Review Table C in Appendix A to ensure the planned power cable
configuration is compatible with the available number of cable connections
at each SSBM and SBM terminal.
NOTE:
If additional cable connections are required, consider using FCI HYSTACK
Type ASA ---U adapters. HYSTACK P/N ASA250U covers NEMA 2-hole
terminals for wire sizes from #8 AWG to 250kcmil. HYSTACK P/N ASA800U
covers NEMA 2-hole terminals for wire sizes from #8 AWG to 800kcmil.
Care must be taken in HYSTACK adapters to ensure the required
phase-to-phase clearance of 1 inch and phase-to-ground clearance of
1 inch (1.5 inches in Canada) is maintained.
For external wiring, including the recommended minimum AWG size of external
wiring, see Tables A, B, O, and P in Appendix A. The power wiring connections for
this equipment are rated at 90
˚
C. If wire is run in an ambient temperature greater
than noted above, higher temperature and/or larger size wire may be necessary.
Control wiring for PowerNet, EPO and optional accessories (such as building
alarms, monitoring interface and Maintenance Bypass control) should be
connected at the customer interface panel at the top of the SSBM Powernode
Panel (A1), which is shown in drawing 164201373---12 in Appendix A.
