The Power Xpert TM 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 Power Xpert 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
1.2.2 Field Installed UPM ).
The Power Xpert 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 upgradability 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 Separate Rectifier Input ).
The Power Xpert 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 Power Xpert 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.

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
