Introduction
The Powerware 9315 Parallel Capacity/Redundant online power protection system
is utilized to prevent loss of valuable electronic information, minimize equipment
downtime, and/or minimize the adverse effect on equipment production due to
unexpected power problems.
The Powerware 9315 Parallel Capacity/Redundant System continually monitors
incoming electrical power and removes the surges, spikes, sags, and other
irregularities that are inherent in commercial utility power. Working with your
building’s electrical system, the Parallel Capacity/Redundant System supplies
clean, consistent power that your sensitive electronic equipment requires for
reliable operation. And during brownouts, blackouts, and other power
interruptions, optional battery racks provide emergency power to safeguard
your operation.
The Parallel Capacity/Redundant system, using the
Powerware
PowerHandlerPlus
t
Switchboard System Bypass Module (SSBM), allows two to
eight UPMs to operate in parallel to provide more capacity than a single UPM and
as backup for each other. The Parallel Capacity/Redundant system can supply up
to 4000 Amps, depending on the SSBM used. In addition, when one UPM is taken
out of service for maintenance or is not operating properly, the redundant UPM
continues to supply uninterrupted power to the critical load. The Parallel
Capacity/Redundant system refers to the SSBM in conjunction with the UPMs. The
Parallel Capacity/Redundant system consists of a Switchboard System Bypass
Module with optional System Maintenance Bypass (SMB), two or more UPMs, and
battery racks or cabinets. Each UPM may have its own battery rack, or may share
the same battery rack with the other UPMs. The SSBM has temporary load bank
tabs to allow full load testing of the UPMs and the SSBM.
Your UPMs functions automatically and requires very little attention during normal
operation. However, you should read and understand the procedures described in
this manual to ensure trouble-free operation. In particular, you should be
thoroughly familiar with the Emergency UPM Off procedure described in Chapter 7
of this manual and Emergency Load Off procedure described in the Powerware
9315 UPS Operation manual provided with the UPM.
This manual describes how to install and operate your Powerware
 9315
Parallel Capacity/Redundant system. The installation section contains instructions
for installing the Powerware PowerHandlerPlus
t
Switchboard System Bypass
Module (SSBM). The operation section contains instructions for operating the
SSBM and UPMs while paralleling for capacity/redundancy. The information you
use depends on the system you purchased.
NOTE: The installation procedures of this manual only refer to the SSBM and its
connection to the UPS modules for parallel capacity/redundancy operation.
The operation section of this manual refers to the operation for the SSBM
and the UPMs when paralleling for capacity/redundancy. For full installation
and operation of the UPMs, refer to the Powerware 9315 UPS Installation
and Powerware 9315 UPS Operation manuals provided with the UPMs.
Each component of your Parallel Capacity/Redundant system is housed in a
free-standing cabinet. The UPM cabinets line up and match in style and color, and
have safety shields behind the doors for hazardous voltage protection. Figure 1
shows a typical Parallel Capacity/Redundant System.
