EATON Powerware®9390 UPS (100–160 kVA) Installation and Operation Manual S 164201604 Rev B powerware.com
Chapter 1Introduction
The Powerware®9390 uninterruptible power supply (UPS) is a true online, continuous-duty,
transformerless, double-conversion, solid-state, three-phase system, providing conditioned
and uninterruptible AC power to protect the customer’s load from all nine power failures.
The Powerware 9390 UPS is available as a single module or a multiple module parallel
system (see paragraph 1.1).
The Powerware online power protection system is used to prevent loss of valuable
electronic information, minimize equipment downtime, and minimize the adverse effect on
production equipment due to unexpected power problems.
The Powerware 9390 UPS continually monitors incoming electrical power and removes the
surges, spikes, sags, and other irregularities that are inherent in commercial utility power.
Working with a building’s electrical system, the UPS system supplies clean, consistent
power that sensitive electronic equipment requires for reliable operation. During
brownouts, blackouts, and other power interruptions, batteries provide emergency power
to safeguard operation.
The UPS system is housed in a single, free-standing cabinet with safety shields behind the
door for hazardous voltage protection. The cabinet es the battery and distribution cabinets
in style and color and can be installed in line-up-and-match or standalone configurations.
Figure 1-1 shows the Powerware 9390 UPS (100–160 kVA).

NOTE
Customer Service Engineer, or the warranty terms specified on page W-1 become void.
This service is offered as part of the sales contract for the UPS. Contact service in
advance (usually a two-week notice is required) to reserve a preferred startup date.
Startup and operational checks must be performed by an authorized Eaton
2.1Creating an Installation Plan
Before installing the UPS system, read and understand how this manual applies to the
system being installed. Use the procedures and illustrations in the following chapters to
create a logical plan for installing the system.
2.2Preparing the Site
For the UPS system to operate at peak efficiency, the installation site should meet the
environmental parameters outlined in this manual. If the UPS is to be operated at an
altitude higher than 1500m (5000 ft), contact your Eaton service representative for
important information about high altitude operation. The operating environment must
meet the weight, clearance, and environmental requirements specified in Drawing
164201604-2 on page A-3 and size requirements specified on Drawing 164201604 -9
starting on page A-46.
The UPS cabinets use forced air cooling to regulate internal component temperature. Air
inlets are in the front of the cabinet and outlets are in the top. You must allow clearance in
front of and above each cabinet for proper air circulation.

2.2.1Environmental Considerations
The life of the UPS system is adversely affected if the installation does not meet the
following guidelines:
쑺 The system must be installed on a level floorsuitableforcomputerorelectronic
equipment.
쑺 The system must be installed in a temperature and humidity controlled indoor area free
of conductive contaminants.
Failure to follow guidelines may void your warranty.
2.2.2Preparing for Wiring the UPS System
NOTE If installing, as part of the UPS system, a maintenance bypass without a rectifier
input breaker, a minimum of two separate feeds with upstream feeder breakers, or one
feed with two upstream feeder breakers, must be provided: one for the UPS and one for
the maintenance bypass input. DO NOT use one feed or a single feeder breaker to
supply both the UPS and the maintenance bypass.
For external wiring requirements, including the minimum AWG size of external wiring, see
Table E through Table G starting on page A-12. The power wiring connections for this
equipment are rated at 90°C. If wire is run in an ambient temperature greater than 30°C,
higher temperature wire and/or larger size wire may be necessary
Control wiring for Emergency Power-off (EPO) and optional accessories (such as building
alarms and monitoring interface) should be connected at the customer interface terminal
blocks located inside the UPS.
LAN and telephone drops, for use with X-Slot connectivity cards, must be supplied by
facility planners or the customer.

load does not require a neutral and there is no neutral conductor connected at the
bypass input, a neutral to ground bonding jumper must be installed. DO NOT install
both a source neutral and a bonding jumper. See Table E through Table G or Table O
through Table Q for neutral bonding jumper wire sizes. Bonding jumper must be
copper wire.
CAUTION
HIGH IMPEDANCE GROUND SOURCES - If the supply source is a high impedance ground (IT)
type, the input neutral conductor must be connected from the source of supply. If there is no
output neutral connected to the UPS, the neutral-forming transformer kit (PN 103005400) may
be used instead of pulling a neutral from the source. If the load requires a neutral, then an
input neutral conductor must be pulled into the UPS. In no circumstances shall a neutral to
ground bonding jumper be installed in the UPS.

CAUTION
DELTA SOURCES (TN-S) - The 9390 UPS system can be operated only from a delta supply
source that is fully floating and if the neutral-forming transformer kit (PN 103005400) is
installed in the UPS. The UPS cannot be operated from a mid-point or end -point grounded
delta supply source. With this type of supply source, there is no capability to provide an output
neutral. In no circumstances shall a neutral to ground bonding jumper be installed in the
UPS.

In the following step, DO NOT move the sensing and EMI wires from the rectifier contactor K1
input terminals. These wires must remain connected to the K1 terminals for proper UPS
operation.
CAUTION
10. Disconnect the phase A, B, and C bypass contactor K5 power input leads only (two
wires per phase) from the rectifier contactor K1 input terminals. Connect these
power leads to the bypass input terminals.
11. Connect phase A, B, and C rectifier input power wiring from the utility source to
the rectifier input terminals in the UPS cabinet. See Appendix A for wiring and
termination requirements and wiring access information. Note wiring connections
for dual-feed systems.
12. Connect phase A, B, and C, and Neutral (if required) bypass input power wiring
from the utility source to the bypass input terminals and neutral terminals in the
UPS cabinet. See Appendix A for wiring and termination requirements and wiring
access information. Note wiring connections for dual-feed systems.
13. If wiring an IDC or IAC, proceed to Step 14; otherwise, proceed to Step 17.
14. Route and connect the output cable between the UPS cabinet and the IDC or IAC.
Refer to the applicable IDC or IAC installation and operation manual, referenced in
paragraph 1.5 on page 1-6, for wiring instructions. See Appendix A for UPS cabinet
wiring access information.
15. Connect phase A, B, and C, and Neutral (if required) power wiring from the IDC or
IAC to the UPS cabinet output and neutral terminals. See Appendix A for wiring
and termination requirements.
16. Proceed to paragraph 3.2.6.3.
17. If wiring a parallel system, proceed to Step 18; otherwise, proceed to Step 20.
CAUTION
Parallel system wiring length should be in accordance with Drawing 164201604-5, sheet
15 of 15, to ensure approximately equal current sharing when in Static Bypass mode.
18. Connect phase A, B, and C, and Neutral (if required) power wiring from the output
and neutral terminals of each uninterruptible power module (UPM) to the module
tie cabinet. See Appendix A for UPM wiring and termination requirements and
wiring access information.

19. Proceed to paragraph 3.2.6.3.
20. Connect phase A, B, and C, and Neutral (if required) power wiring from the output
and neutral terminals to the critical load. See Appendix A for wiring and
termination requirements and wiring access information.
21. Proceed to paragraph 3.2.6.3.
