1 Introduction
The Eaton® Powerware® 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 all nine power
failures. The Powerware 9395 UPS is available as a single module system.
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 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 Powerware 9395 UPS (450–550 kVA).
NOTE
Startup and operational checks must be performed by an authorized Eaton Customer
Service Engineer, or the warranty terms specified on page 75 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.
