Introduction - Eaton Powerware 9315 Installation And Operation Manual

Introduction

The Powerware 9315 Parallel Capacity/Redundant System online power protection
can be 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 System Bypass Module (SBM),
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 2000 Amps, depending on the SBM 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 SBM in conjunction with the
UPMs. The Parallel Capacity/Redundant system consists of one 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.
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
Parallel Capacity/Redundant system. The installation section contains instructions
for installing the System Bypass Module (SBM). The operation section contains
instructions for operating the SBM 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 SBM and its
connection to the UPS modules for parallel capacity/redundancy operation.
The operation section of this manual refers to the operation for the SBM 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 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.
