Chapter 2 Safety Warnings
DANGER
This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE
PARTS inside the UPS.
WARNING
S This UPS contains its own energy source (batteries). The UPS output may carry live
voltage even when the UPS is not connected to an AC supply.
S To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity
controlled, indoor environment, free of conductive contaminants. Ambient temperature
must not exceed 40°C (104°F). Do not operate near water or excessive humidity (95%
maximum).
S To reduce the risk of fire, connect only to a circuit provided with 100 amperes maximum
branch circuit overcurrent protection in accordance with the National Electrical Code®
(NEC®), ANSI/NFPA 70.
S Output overcurrent protection and disconnect switch must be provided by others.
CAUTION
S Batteries can present a risk of electrical shock or burn from high short circuit current.
Observe proper precautions. Servicing should be performed by qualified service personnel
knowledgeable of batteries and required precautions. Keep unauthorized personnel away
from batteries.
S Proper disposal of batteries is required. Refer to your local codes for disposal
requirements.
S Never dispose of batteries in a fire. Batteries may explode when exposed to flame.

Floor Loading
When planning the installation, consider the UPS weight for floor
loading. The strength of the installation surface must be adequate for
point and distributed loadings. The approximate weights are shown in
the following table.
Clearances
The following clearances are recommended for the Eaton 9155 UPS:

UPS SETUP
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.
1. Remove the two M10 bolts securing the stabilizing bracket to the
pallet (see Figure 2).
M10 Bolts
NOTE Be sure to retain the stabilizing bracket and hardware for later re-assembly onto the
cabinet.

3. Remove the front cover from the bottom cabinet to access the front
shipping bracket.
Press and release the handle latch at the bottom of the cover and
then lift the cover up and off the cabinet.
4. Remove the three M10 bolts securing the rear shipping pad to the
pallet and remove the shipping pad (see Figure 3).
NOTE Hold the back of the cabinet so that the bolts can be removed easily without the
cabinet rolling backward.
5. Remove the two M10 bolts securing the front shipping bracket and
remove the bracket.

UPS SETUP
NOTE Be sure to support the front and back of the cabinet when rolling it off the pallet to
prevent tipping.
7. Slowly roll the cabinet toward the rear of the pallet. Once the pallet
tilts, continue rolling the cabinet down the pallet until the cabinet
touches the floor (see Figure 4).
If needed, adjust the leveling feet so that the cabinet will roll.
8. With the cabinet supported, slowly pull the pallet away from the
cabinet (see Figure 5).

PARALLEL INSTALLATION
WARNING
Only qualified service personnel (such as a licensed electrician) should perform the UPS
installation and initial startup. Risk of electrical shock.
Compare the circuit breaker ratings and wire sizes to the ones in
the following wiring table:
*Use only 75°C-rated copper wire. Minimum wire size is based on 120/208 full load
ratings applied to NEC Code Table 310‐15(B)(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.
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.

1. Remove the front covers of all cabinets, starting with the top
cabinet.
Press and release the handle latch at the bottom of each cover and
then lift the cover up and off the cabinet (see Figure 17).

3. Set the jumper pins on the Powerware Hot Sync CAN Bridge Card
according to the parallel configuration (see Figure 18):
S If only two UPSs are paralleled, then set both cards to Pins 1
and 2.
S For three paralleled UPSs, set the cards of the first and last UPS
to Pins 1 and 2; set the card for the middle UPS to Pins 2 and 3.

INSTALLING OPTIONS
NOTE If you are installing another X-Slot card, be sure to install the Powerware Hot Sync
CAN Bridge Card in X-Slot 2.
4. Loosely install the Powerware Hot Sync CAN Bridge Card into an
open X-Slot on the front of the UPS. You may want to remove the
terminal block from the CAN Bridge Card for better wiring access.
6. Install the CAN Bridge Card wiring between each UPS (see
Figure 19). Be sure to check correct polarity for Pins 8 and 9:
7. Install the pull-chain wiring between the CAN Bridge Card and
Signal Input 2 on each UPS and daisy chain the wiring to each UPS.
Be sure to check correct polarity (see Figure 19):
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 an Eaton 9155 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.
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:
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.

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.
2. Verify that all battery circuit breakers are in the OFF position (see
Figure 26).
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 26.
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.
