EATON Powerware®9355 Parallel UPS (10/15 kVA) User’s Guide S 164201601 Rev A www.powerware.com
Chapter 1 Introduction
A parallel system with up to four 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
Area Network (CAN) Bridge Card provides connectivity for system
metering and operational mode control. The parallel system consists of
two to four UPSs, each with a parallel CAN Bridge Card and a parallel
cabinet.
Figure 1 shows the Powerware 9355 UPS and an optional Extended
Battery Module (EBM).

Chapter 4 Parallel Installation
The Powerware 9355 has the following power connections:
S 3-phase (L1, L2, and L3), neutral, and ground connection for
rectifier/bypass input
S 3-phase (L1, L2, and L3), neutral, and ground connection for load
output
The nominal input/output voltages are:
S 120/208 or 127/220 Vac
Output overcurrent protection and disconnect switch must be provided
by others.
Figure 19 and Figure 20 beginning on page 25 show the oneline
diagrams.
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:
WARNING
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 to the ones in Table 1 on
page 21.
NOTE To accommodate the feature of easy system expandability, it is recommended that
initial installation of the Powerware 9355 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.

Table 310-16. Code may require a larger AWG size than shown in this table because of temperature, number of

Per NEC article 300-20(a), all three-phase conductors must be run in the same conduit. Neutral and ground must be
run in the same conduit as the phase conductors.
3
Conduit is sized to accommodate one neutral conductor the same size as the phase conductor and one #8 AWG
ground conductor. If two neutral conductors or an oversized neutral conductor are to be installed, check the size of the
conduit needed to accommodate the extra wire or size and use that conduit size in place of the conduit size listed.
Conduit sizes were chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW, THHW, THW-2.

INSTALLING OPTIONS
Powerware Hot Sync CAN Bridge Card
The Powerware Hot Sync CAN Bridge Card, shown in Figure 22, can be
installed to provide connectivity for operational mode control and
metering of a parallel system at any UPS in the system.
Figure 22. Powerware Hot Sync CAN Bridge Card
To install the Powerware Hot Sync CAN Bridge Card:
1. Remove the front covers of all cabinets, starting with the top
cabinet.
Plug-In Terminal Block
28
Press and release the handle latch at the bottom of each cover and
then lift the cover up and off the cabinet (see Figure 23).

INSTALLING OPTIONS
2. Strip shielded, four-wire, twisted-pair wire for CAN Bridge Card
wiring. Recommended wire size is 18 AWG maximum.
3. Install the CAN Bridge Card wiring between each UPS (see
Figure 24). Be sure to check correct polarity for Pins 8 and 9:
S Connect SHIELD Pin 10 on all cards together.
S Connect CAN H Pin 9 and CAN L Pin 8 (twisted pair) on all cards
together.
S Connect COM Pin 4 and NC Pin 3 (twisted pair) on all cards
together.
4. Wire the factory-installed pull-chain wiring to Signal Input 2 on each
UPS and daisy chain the wiring to each UPS as shown in Figure 24.
Be sure to check correct polarity:
S Connect COM Pin 4 to Signal Input 2 Pin 1 on each UPS.
S Connect NC Pin 3 to Signal Input 2 Pin 2 on each UPS.
CAUTION
If polarity or wiring is not correct, the parallel system does not operate normally. For
example, when shutting down one UPS, the remaining UPS transfers the load to bypass
instead of supporting the load. Verify all CAN Bridge Card wiring is correct for proper
operation.
NOTE Signal Input 2 can still be used for building alarms; it is automatically rerouted to
the CAN Bridge Card.

Chapter 6 Stabilizing the Cabinet
NOTE For seismic installations, you MUST order and install a Powerware 9355 UPS
seismic kit; do not use the following instructions.
NOTE For non-seismic installations, you MUST install the stabilizing bracket on all 3-high
cabinets. The stabilizing bracket is optional for 2-high cabinets.
To stabilize the cabinet(s):
1. Lower the leveling feet to prevent the cabinet from rolling.
Figure 27. Lowering the Leveling Feet
2. Attach the stabilizing bracket to the bottom of the cabinet rear panel
using the retained hardware from the shipping pallet according to
the cabinet configuration:
S For one cabinet, see Figure 28.
S For two cabinets, see Figure 29.
S For three cabinets, see Figure 30.
NOTE No more than three cabinets can be attached together. For four cabinets, use two of
the two-cabinet installations. For five cabinets, use one three-cabinet and one two-cabinet
installation.
3. Use the holes and slots in the bottom of the bracket to attach the
cabinet to the flooring if desired.
4. Continue to one of the following sections:
S “Extended Battery Module Installation” on page 37 to install
optional EBMs.
S “Operation” on page 41 to start up the parallel UPS system.

Chapter 7 Extended Battery Module Installation
NOTE A maximum of 22 battery strings can be installed in one configuration, including
UPS batteries (4 EBM-64 models or 3 EBM-96 models). UPS-32 models contain 2 strings;
UPS-64 models contain 4 strings; EBM-64 models contain 4 strings; and EBM-96 models
contain 6 strings.
NOTE For non-seismic installations, you MUST install the stabilizing bracket on all 3-high
cabinets. The stabilizing bracket is optional for 2-high cabinets.
NOTE In a parallel system, each UPS should have the same number of Extended Battery
Modules (EBMs) to ensure equivalent runtimes.
To install the optional EBM:
1. Position the EBM adjacent to the next cabinet.
2. Verify that all battery circuit breakers are in the OFF position (see
Figure 31).
3. Remove the two ground straps from the EBM rear panel.
4. Install one ground strap between the UPS and EBM rear panels as
shown in Figure 31.
5. If additional EBMs are installed, attach another ground strap
between the first and second EBM as shown in Figure 31. Repeat
for each additional EBM.
6. Plug the EBM cable into the UPS battery connector.
7. If additional EBMs are installed, plug the EBM cable of the second
cabinet into the battery connector on the first EBM. Repeat for each
additional EBM.

Chapter 10 Troubleshooting
The Powerware 9355 is designed for durable, automatic operation and
also alerts you whenever potential operating problems may occur.
Usually the alarms shown by the control panel do not mean that the
output power is affected. Instead, they are preventive alarms intended
to alert the user. Use the following troubleshooting chart to determine
the UPS alarm condition.
Typical Alarms and Conditions
The following table describes typical alarms and conditions; check the
Event Log through the control panel for a list of active alarms. If an alarm
