Chapter 1
Introduction
Eaton’s 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 power failures.
The Powerware 9395 UPS (650–825 kVA) contains two sections: an integrated
system bypass module (ISBM) or an Input Output Module (IOM) rated for a maximum
of 825 kVA and an Uninterruptible Power Module (UPM) section containing three
UPMs. Each UPM is rated for a maximum of 275 kVA for a total maximum of 825
kVA.
The UPS is available as a single unit or an optional multiple unit distributed bypass
system (see paragraph 1.2.7).
The UPS Plus 1 model using the Field Installed UPM (FI−UPM) provides N+1
redundancy for the system (see paragraph 1.2.1).
The Powerware 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 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 is housed in a free-standing cabinet, divided into two sections to facilitate
shipping. The sections match in style and color and have safety shields behind the
doors for hazardous voltage protection. The FI−UPM matches the UPS in style and
color. Figure 1-1 shows the Powerware 9395 UPS (650–825 kVA). Figure 1-2 shows
the Powerware 9395 (650–825 kVA) UPS 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.
