Options and Accessories

Contact an Eaton sales representative for information about the following options.
1.3.1

Integrated Battery Cabinets

Battery backup protection can be provided by equipping the UPS system with Power Xpert 9395P-900 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 Eaton
Installation Manual (P-164000580) for specifics on battery cabinet usage with the Power Xpert 9395P-900.
1.3.2

Field Installed UPM

A Field Installed UPM (FI-UPM) provides upgradability for the Power Xpert 9395P-900 Two 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 ISBM section and is wired directly to the UPS. No input or output wiring changes are
needed for a capacity increase if the original installation was wired for increased capacity. Operation remains
the same as the original UPS.
1.3.3

Sync Control

An optional Power Xpert 9395P-900 Sync Control maintains the critical load outputs of two separate single
module 9395P-900 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.
1.3.4

Single-Feed Kit

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.
1.3.5 Distributed Bypass System
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
Powerware Hot Sync Controller Area Network (CAN) Bridge Card provides connectivity and operational mode
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 is provided by the customer and 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 UPMs will go to bypass instead of just the UPM needing service, decreasing
critical load protection. With dual auxiliary MOBs, one UPM can be bypassed while the remaining UPMs
support the load as long as the remaining UPMs have the capacity to do so.
