Chapter 1 Introduction
A parallel system with up to three uninterruptible power supplies (UPSs)
can be installed to provide a parallel capacity and/or redundant system.
This load sharing system provides more capacity than a single UPS and
can provide backup, depending on the load and configuration. In
addition, when one UPS is taken out of service for maintenance or is not
operating properly, a redundant UPS continues to supply uninterrupted
power to the critical load. A parallel Powerware®Hot Sync®Contoller
Area Network (CAN) Bridge Card provides connectivity for system
metering and operational mode control. The parallel system consists of
two or three UPSs, each with a CAN Bridge Card and a parallel tie
cabinet.
Figure 1 shows the Powerware 9155 UPS and an optional Extended
Battery Module (EBM).

Unloading the Cabinet(s)
The following tools are required for unloading the cabinet(s):
S15 mm wrench or socket
S7 mm nutdriver or socket
CAUTION
The UPS and Extended Battery Module (EBM) are heavy (see page 8). Unloading the cabinets
requires at least two people to safely remove the cabinets from the pallet.
To remove the UPS or EBM from the shipping pallet:
1. Remove the two M10 bolts securing the stabilizing bracket to the
pallet (see Figure 2).
M10 Bolts
Figure 2. Removing the Stabilizing Bracket Bolts
2. Remove the four M4 screws securing the stabilizing bracket to the
cabinet rear panel and remove the bracket (see Figure 3). Retain the
hardware for later use.
NOTE Be sure to retain the stabilizing bracket and hardware for later re-assembly onto the
cabinet.

WARNING
Only qualified service personnel (such as a licensed electrician) should perform the UPS
installation and initial startup. Risk of electrical shock.
To hardwire the parallel system:
1. Verify that the electrical connections to the installation site have
been properly installed.
2. A wall-mounted, user‐supplied, readily‐accessible disconnection
device must be incorporated in the input wiring.
Compare the circuit breaker ratings and wire sizes to the ones in
the following wiring table:
Table 1. Circuit Breaker Ratings
UPS Capacity Input Circuit Breaker Rating Minimum Wire Size*
8 kVA 60A 4 AWG (21.2 mm2)
10 kVA 80A 3 AWG (26.7 mm2)
12 kVA 100A 2 AWG (33.6 mm2)
15 kVA 100A 2 AWG (33.6 mm2)
*Use only 75°C-rated copper wire. Minimum wire size is based on 120/208 full load
ratings applied to NEC Code Table 310‐16. Code may require a larger AWG size than
shown in this table because of temperature, number of conductors in the conduit, or
long service runs. Follow local requirements.
NOTE To accommodate the feature of easy system expandability, it is recommended that
initial installation of the Powerware 9155 UPS contain wiring to support the maximum
capacity of the UPS cabinet.
3. Switch off utility power to the distribution point where the parallel
tie cabinet and UPSs will be connected. Be absolutely sure there is
no power.
4. Determine your equipment's grounding requirements according to
your local electrical code.
