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 Three UPM UPS (650–825 kVA) contains two sections: a section
configured either as 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 Plus 1 model (650–825 kVA) using the Field Installed UPM (FI-UPM)
provides N+1 redundancy for the system (see paragraph 1.2.1).
The Eaton 9395-825/550 Two UPM UPS (450–550 kVA) contains two sections: an
ISBM or an IOM rated for a maximum of 825 kVA (to provide future upgradability) and
an UPM section containing two UPMs. Each UPM is rated for a maximum of 275 kVA
for a total maximum of 550 kVA. The
FI-UPM
is not supplied as standard, but is
available as an option to provide upgradeability to a maximum of 825 kVA. Adding the
FI-UPM
can also provide N+1 redundancy if the power requirements are less than the
two UPM rating.
The UPS is available as a single unit or as an optional multiple unit distributed bypass
system (see paragraph 1.2.5).
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 free‐standing cabinet, divided into two sections to facilitate
shipping. The sections match in style and color and have safety shields behind the
door and front panels for hazardous voltage protection. The FI-UPM matches the UPS
in style and color. Figure 1‐1 shows the Eaton 9395 Three UPM UPS (650–825 kVA).
Figure 1‐2 shows the Eaton 9395 Plus 1 UPS (650–825 kVA) UPS with the FI-UPM.
Figure 1‐3 shows the Eaton 9395-825/550 Two UPM UPS (450–550 kVA). Figure 1‐4
shows the Eaton 9395-825/550 Two UPM UPS with the Field Installed UPM
(450–825 kVA).
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.
