Revision 002 User’s and Installation Guide
1.1.5 Power Management Software
Eaton 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 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 and is wired directly to the UPS. No input or output wiring changes are needed for
redundancy. Operation remains the same as for the original UPS.
1.2.2 Sync Control
An optional Eaton 9395P Sync Control maintains the critical load outputs of two separate single
module Eaton 9395P UPS systems in synchronization. This option facilitates the uninterrupted transfer
of the load from one load bus to another by means of a transfer switch. The Sync Control is housed in
a wall-mounted panel that can be located between the UPS units for easy wiring.
1.2.3 Maintenance Bypass Module
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.
1.2.4 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 extenders for each phase, and the hardware
required for installation.
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 one to four UPMs.
A distributed bypass UPS system with two to five UPS units 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 redundancy, depending on the load and configuration. In addition, when one UPM or UPS is
taken out of service for maintenance or is not operating properly, a redundant UPM or UPS continues
to supply uninterrupted power to the critical load. An Eaton HotSync® Controller Area Network (CAN)
provides connectivity and operational mode control. The distributed bypass system consists of two to
five UPS units each with a CAN card (for paralleling the UPSs), and a customer-supplied tie cabinet or
load distribution panel to act as a tie point.
The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary contacts for control
of the system. Without dual auxiliary MOBs, UPSs are not allowed to go to bypass individually during
servicing. All UPSs will go to bypass instead of just the UPS needing service, decreasing critical load
protection. With dual auxiliary MOBs, one UPS can be bypassed while the remaining UPSs support the
load as long as the remaining UPMs have the capacity to do so.
