Eaton
9390 UPS (20–80 kVA) and 9390IT (20-40 kVA) Installation and Operation Manual
Contact your Eaton sales representative for information about the following options:
1.2.1
Integrated Battery Cabinets
NOTE This item cannot be used with the 9390IT internal battery configuration.
Battery backup protection can be enhanced by equipping the UPS system with up to
four Eaton 9390 battery cabinets containing sealed lead‐acid, maintenance‐free
batteries. The battery cabinets are available in small and large sizes, with 192-cell (for
208V UPS models only), 216-cell, and 240-cell configurations (for 380V, 400V, 415V,
480V UPS models). The cabinets are designed for line-up-and-match installation, but
may be installed separate from the UPS cabinet.
NOTE NiCad batteries can also be used with the UPS, although firmware and EEP settings would need
modification for proper operation. Please consult your local Eaton Service representative for additional
information. The 9390 T models cannot use the NiCad battery option.
1.2.2
Integrated Distribution Cabinet
The Integrated Distribution Cabinet (IDC) provides adaptation and expansion with
distribution panelboards, distribution circuit breakers, a maintenance bypass switch,
and voltage transformation. The IDC is housed in a single, free‐standing cabinet
designed for line-up-and-match installation, but may be installed separate from the
UPS cabinet.
1.2.3
Integrated Accessory Cabinets (IAC-B, IAC-T, and IAC-D)
The following Integrated Accessory Cabinets (IACs) are designed for use with the
Eaton 9390/9390IT three-phase UPSs:
S
The IAC-B provides maintenance bypass functions.
S
The IAC-T provides parallel tie cabinet or parallel tie cabinet with maintenance
bypass functions.
S
The IAC-D provides power distribution options for servers, racks, and other
equipment via distribution panelboards, or distributes power to larger loads via
distribution circuit breakers.
The IACs are housed in single, free‐standing cabinets designed for line-up-and-match
installation, but may be installed separate from the UPS cabinet.
1.2.4
Powerware Hot Sync Parallel System
A parallel UPS system with two to four uninterruptible power modules (UPMs) 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 UPM is taken out of service for
maintenance or is not operating properly, a redundant UPM continues to supply
uninterrupted power to the critical load. A Powerware Hot Sync CAN Bridge Card
provides connectivity for system metering and operational mode control. The parallel
system consists of two to four UPMs each with a parallel CAN Bridge Card, and a
module tie cabinet or load distribution panel to act as a tie point. Each UPM requires a
separate battery cabinet.
