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 upgradability for the Power Xpert 9395 Three UPM UPS. 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.

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 1000–1100 kVA 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.
All sources that feed the separate rectifier inputs must be from a common ground point.

There are two types of redundancy: UPS based (based on the number of UPSs) and UPM based (based on the
number of UPMs). Each UPS contains three or four UPMs.
A distributed bypass UPS system with two to five UPSs can be installed to provide a capacity and/or redundant
system. This load sharing system provides more capacity than a single UPS, and can provide backup,
depending on the load and configuration. In addition, when one UPM is taken out of service for maintenance or
is not operating properly, a redundant UPM continues to supply uninterrupted power to the critical load. A

control. The distributed bypass system consists of two to five UPSs each with a parallel CAN card, and a
customer-supplied tie cabinet or load distribution panel to act as a tie point.
All UPSs in the distributed bypass system must contain the same number of UPMs. Mixed UPS kVA ratings are
not permitted.
The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary contacts for control of the
system. Without dual auxiliary MOBs, UPMs are not allowed to go to bypass individually during servicing. All
