User’s and Installation Guide
1 Introduction
The Eaton® 9395 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 power failures.
The Eaton 9395 four-UPM UPS (1000-1100 kVA) contains three sections: an integrated system bypass
module (ISBM) or an Input Output Module (IOM) rated for a maximum of 1100 kVA, an Uninterruptible
Power Module (UPM) section containing three UPMs, and a Field Installed UPM (FI-UPM). Each UPM
is rated for a maximum of 275 kVA for a total maximum of 1100 kVA.
The Eaton 9395 three-UPM UPS (650-825 kVA) contains two sections: an ISBM or an IOM rated for a
maximum of 1100 kVA (to provide future upgradeability) and an UPM section containing three UPMs.
Each UPM is rated for a maximum of 275 kVA for a total maximum of 825 kVA. The FI-UPM is not
supplied as standard, but is available as an option to provide upgradeability to a maximum of 1100 kVA.
The UPS is available as a single unit or as an optional multiple unit distributed bypass system (see
Section 1.2.5).
The Eaton 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 Eaton 9395 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 matches 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 Eaton 9395 UPS (675 - 825 kVA), Figure 1-2 shows the Eaton 825/550 kVA and
Figure 1-3 shows the Eaton 9395-1100 kVA.
NOTE
Startup and operational checks must be performed by an authorized Eaton Customer Service
Engineer, or the warranty terms specified on page 144 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.
1.1 UPS standard features
The UPS has many standard features that provide cost-effective and consistently reliable power
protection. The descriptions in this section provide a brief overview of the UPS standard features.
1.1.1 Installation features
Each UPS section is shipped separately. The sections are mechanically and electrically joined at the
installation site. Sections can be permanently bolted to the floor.
Power wiring/busbars can be routed through the top or bottom of the cabinet with connections made
to easily accessible terminals. Control wiring is routed through the top of the cabinet and must be
installed in accordance with national wiring methods.
