9395P 250 kVA / 275 kVA / 300 kVA
User’s and Installation Guide
1 Introduction
The Eaton Power Xpert ® 9395P 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 9395P UPS (250 kVA PF 1.0, 275 kVA PF 1.0 and 300 kVA PF 0.9) 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 250 kVA / 275 kVA / 300 KVA and an Uninterruptible
Power Module (UPM) rated for a maximum of 250 kVA / 275 kVA / 300 KVA.
The UPS is available as a single unit or as an optional multiple unit distributed bypass system (see
Section 1.2.6).
The Eaton 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 9395P 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 1-2 shows the Eaton 9395P UPS 250 kVA / 275 kVA / 300 KVA and Figure 1-2 shows a
typical single-module system.
NOTE
Startup and operational checks must be performed by an authorized Eaton Customer Service
Engineer, or the warranty terms specified 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.
1.1 UPS standard features
The UPS has many standard features that provide cost-effective and consistently reliable power
protection. The descriptions in this section provide a brief overview of the UPS standard features.
1.1.1 Installation features
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. Line-up-and-match
battery cabinets are wired through the side panels of the units. Optional X-Slot connectivity cards are
quickly installed at the front of the unit and are hot-pluggable.
1.1.2 Control panel
The HMI control panel, located on the front of the UPS, is an optional 7” or 10” touchscreen to
control the operation of the UPS and to display the status of the UPS system. See Chapter 7: “UPS
