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 Eaton 9395 825/550 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. Adding the
FI-UPM
can also provide N+1
redundancy if the power requirements are less than the two UPM rating.
1.2.2
Sync Control
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.
1.2.3
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.
1.2.4
Separate Rectifier Input
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 supplied by the customer.
1.2.5
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 can contain three to 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.
