Chapter 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 225–275 kVA UPS cabinet contains two sections, an integrated
system bypass module (ISBM) rated for a maximum of 275 kVA and a single
Uninterruptible Power Module (UPM) rated for a maximum of 275 kVA.
The UPS is available as a single unit or an optional multiple unit distributed bypass
system (see paragraph 1.2.7).
The Eaton 9395 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 is housed in a single, free‐standing cabinet with safety shields behind the
door and front panels for hazardous voltage protection. The cabinet matches the
battery and distribution cabinets in style and color. Figure 1‐1 shows the Eaton 9395
UPS (225–275 kVA). Figure 1‐2 shows the Eaton 9395 UPS (225–275 kVA) with the
FI-UPM.
NOTE Startup and operational checks must be performed by an authorized Eaton 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 an Eaton service representative in advance (usually a two-week notice is
required) to reserve a preferred startup date.

Cabinets can be permanently bolted to the floor.
Power and control wiring can be routed through the top or bottom of the cabinet with
connections made to easily accessible terminals. External sensing and monitoring
control wire must be installed in accordance with Class 1 wiring methods.
1.1.2 Control Panel
The control panel, located on the front of the UPS, contains a liquid crystal display
(LCD) and pushbutton switches to control the operation of the UPS and to display the
