Introduction
Eaton 9E UPS (40–60 kVA, 208/220V) Installation and Operation Manual P-164000058—Rev 4 www.eaton.com/powerquality 1-3
1.2.3 Integrated Transformer Cabinet
An single transformer Integrated Transformer Cabinet (ITC) provides three-phase 480 Vac input to three-phase
208Y/120 Vac output voltage transformation and isolation for input to the Eaton 9E UPS. An optional Dual
transformer ITC adds three-phase 208 Vac input to three-phase 480Y/277 Vac output voltage transformation
and isolation for output to the critical load. The ITC is housed in a single, free-standing cabinet designed for
line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended
installation location for an adjacent ITC is to the left of the UPS cabinet.
1.2.4 Integrated Accessory Cabinet-Bypass
An Integrated Accessory Cabinet-Bypass (IAC-B) provides maintenance bypass functions. The IAC-B is
available in a three breaker configuration enabling power to completely bypass the UPS. The UPS can then be
safely serviced or replaced without interrupting power to critical systems. A four breaker configuration is
available to provide a convenient method for removing power from the UPS when using the maintenance
bypass to supply the load. The IAC-B is housed in a single, free-standing cabinet designed for line-up-and-match
installation, but may be installed separate from the UPS cabinet. The recommended installation location for an
adjacent IAC-B is to the left of the UPS cabinet.
1.2.5 Integrated Accessory Cabinet-Tie
An Integrated Accessory Cabinet-Tie (IAC-T) provides the ability to parallel up to four UPSs together for
increased capacity and/or redundant capability. The IAC-T is housed in a single, free-standing cabinet designed
for line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended
installation location for an adjacent IAC-T is to the left of the UPS cabinet.
1.2.6 Integrated Accessory Cabinet-Tie and Bypass
An Integrated Accessory Cabinet-Tie and Bypass (IAC-TB) provides the ability to parallel two UPSs together for
increased capacity and/or redundant capability. In addition, maintenance bypass functions enable power to
completely bypass the UPS power module. The IAC-T is housed in a single, free-standing cabinet designed for
line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended
installation location for an adjacent IAC-T is to the left of the UPS cabinet.
1.2.7 Parallel System
A parallel UPS system with up to four 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
Controller Area Network (CAN) provides connectivity for system metering and operational mode control. The
parallel system consists of two to four UPSs each with a parallel CAN, and either a IAC-T or IAC-TB to act as a
tie point and to control the output.
1.2.8 Reduced Battery String Model
The Eaton 9E-40 model is configured with six battery strings instead of eight to optimize the run time for 40 kVA
with a subsequent reduction in cost and weight. If increased battery run time is required in the future, an
upgrade kit is available to increase the internal battery system to eight strings, converting the Eaton 9E-40 to a
Eaton 9E–60/40. After the upgrade kit is installed, the Eaton 9E–60/40 is also upgradable to a Eaton 9E–60/60
with a firmware upgrade installed by an authorized Eaton Customer Service Engineer.
NOTE All UPSs in a parallel system must have the same battery configuration.
