Introduction
• X-Slot Communication Bays– Four communication bays are standard equipment. One to four optional X-
Slot ® connectivity cards can be installed in the UPS module at any time. X-Slot cards are quickly installed at
the front of the UPS and are hot-pluggable. See

A three-stage charging system increases battery service life by optimizing recharge time, and protects batteries
from damage due to high current charging and inverter ripple currents. Charging at high currents can overheat
and damage batteries.

Battery backup protection can be provided by equipping the UPS system with Power Xpert 9395 battery
cabinets containing sealed lead-acid, maintenance-free batteries. The cabinets are designed for standalone
installation and may be installed adjacent to the UPS or in a separate location. The recommended installation
location for adjacent battery cabinets is on the right side of the UPS cabinet to allow for future expansion using
an external module.
Consult the Power Expert 9395 Integrated Battery Cabinet (Model 1085 and 1085HR) Installation Manual for
specifics on battery cabinet usage with the PowerXpert 9395.

A Field Installed UPM (FI-UPM) provides N+1 redundancy for the UPS system. The FI-UPM may be installed at
any time in the future when power needs change. The module cabinet is installed on the left side of the UPS
cabinet and is wired directly to the UPS. No input or output wiring changes are needed for redundancy.
Operation remains the same as the original UPS.

The Maintenance Bypass Module (MBM) enables power to completely bypass and isolate the UPS so that the
UPS can be safely serviced or replaced without interrupting power to critical systems.

An optional Eaton 9395 Sync Control maintains the critical load outputs of two separate single module Eaton
9395 UPS systems in synchronization. This option facilitates the uninterrupted transfer of the load from one
load bus to another by means of transfer switches. The Sync Control is housed in a wall–mounted panel that
can be located between the UPS units for easy wiring.

An optional kit is available for converting the dual-feed rectifier and bypass inputs to a single-feed configuration.
The kit consists of jumpers and bus bar extensions for each phase, and the hardware required for installation.

If a FI-UPM is to be installed with the Power Xpert 9395 550/275 UPS at the initial installation or in the future,
the UPS can be supplied with separate rectifier inputs for each UPM. Separate inputs provide increased
flexibility and reliability by allowing multiple input sources to supply the UPS. Input circuit breaker CB1 is not
installed with this configuration. AC input control to the UPS and each UPM rectifier is to be provided by the
customer.
