INTRODUCTION
EATON Powerware ® 9395 UPS (1000–1100 kVA) Installation and Operation Manual S 164201764 Rev 1 www.powerware.com 1−4
1.1.5 Power Management Software
Powerware LanSafe ® Power Management Software is bundled as part of the
Software Suite CD shipped with the UPS. See Chapter 8, Communication," for
additional information.
1.2 Options and Accessories
Contact an Eaton sales representative for information about the following options.
1.2.1 Field Installed UPM
A Field Installed UPM (FI−UPM) provides upgradability for the Powerware 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 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 with increased capacity in mind.
Operation remains the same as the original UPS.
1.2.2 Inherent Redundancy
To deliver greater reliability, the Powerware 9395 UPS can be configured by an
authorized Eaton Customer Service Engineer
for inherent redundancy. When
configured, the UPS automatically becomes redundant if the load is at or below the
capacity of the UPMs minus the capacity of one UPM. Under normal conditions the
UPMs in the UPS share the load equally. If one or more UPMs becomes unavailable
and the load is at or below the capacity of remaining UPMs, the remaining UPMs
supply the load instead of transferring to bypass.
If the capacity of the UPMs falls below the redundancy level or the load increases
above redundancy level, but is still able to maintain the load, a loss of redundancy
alarm is sounded. If the load exceeds the capacity of remaining UPMs, the UPS
transfers to bypass.
1.2.3 Sync Control
An optional Powerware 9395 Sync Control maintains the critical load outputs of two
separate single module Powerware 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.
