Powerware 9315 (500 kVA--750 kVA) Installation and Operation

Introduction
Congratulations on your purchase of a Powerware 9315 (500 kVA---750 kVA)
Uninterruptable Power Supply! The Powerware online power protection system is
used 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 UPS 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 UPS
System supplies clean, consistent power that your sensitive electronic equipment
requires for reliable operation. And during brownouts, blackouts, and other power
interruptions, optional battery strings provide emergency power to safeguard your
operation.
The UPS system is housed in a free-standing cabinet, divided into three sections to
facilitate shipping. The cabinet sections line up and match in style and color, and have
safety shields behind the doors for hazardous voltage protection. The following
illustration depicts a typical Powerware 9315 (500 kVA---750 kVA) UPS System.

Basic System Configurations
These basic UPS system configurations are possible:
·Single Module UPS and one battery string
·Multi-Module (Parallel for Capacity/Redundancy) UPS System consisting of two
or more UPS modules, with one battery string for each module and a
Hot---Sync Capacity module
·Multi-Module (Parallel for Capacity/Redundancy) UPS System consisting of two
or more UPS modules, with one common battery string and a Hot---Sync
Capacity module
The optional Hot---Sync Capacity system (Parallel for Capacity/Redundancy), using a
System Bypass Module (SBM), allows two or more 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 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.
You can enhance any of these system configurations by adding optional accessories,
such as a Remote Monitor Panel (RMP), Relay Interface Module (RIM), Supervisory
Contact Module (SCM), or Remote Emergency Power Off (EPO) control.
Using This Manual
Your UPMs function automatically and require 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.
The information in this manual is divided into the sections and chapters listed.
The system you are installing dictates which parts of this manual you should read.
Everyone should read the Introduction, Chapters 1 and 2 and Chapters 7 through 12.
Introduction
The Introduction provides a brief description of the UPS system, a description of the
content of each chapter, safety, text conventions used in the manual and reference
information.
Section I

installation of your UPS system. It discusses equipment environmental
requirements, inspecting, and unpacking cabinets.
·Chapter 2 -- Installing the UPS System -- describes how to install the UPS
cabinets and optional equipment.
·Chapter 3 -- Installing Batteries -- provides battery safety and installation
information.
·Chapter 4 -- Installing a Remote Battery Disconnect -- describes how to
install the UPS battery disconnect.

Conventions Used in This Manual
The text in this manual uses these conventions:
·Bold type highlights important concepts in discussions, key terms in
procedures, and menu options.
·Italic type highlights notes and new terms where they are defined.
·Rectangular boxes containing bold type are warnings or cautions that pertain to
the Parallel Capacity system or its electrical connections.
In this manual, the term UPS refers only to the UPS cabinet and its internal elements.
The term UPS system refers to the entire power protection system—the UPS modules,
battery strings and options or accessories installed.
Safety Considerations
The UPS cabinet is designed for industrial or computer room applications, and contain
safety shields behind the doors. However, the UPS system is a sophisticated power
system and should be handled with appropriate care, following these guidelines:
·Keep surroundings clean and free from excess moisture.
·Do not operate the UPS system close to gas or electric heat sources.
·The system is not intended for outdoor use.
·The operating environment should be maintained within the parameters
stated in this manual.
·Keep the cabinet doors closed and locked to ensure proper cooling airflow
and to protect personnel from dangerous voltages inside the unit.
·The UPS system contains its own power source. Lethal voltages are
present even when the UPS is disconnected from utility power.
WARNING:
Only AUTHORIZED SERVICE PERSONNEL should perform maintenance on or
service the UPS system.
If service or routine maintenance is required:
·Ensure all power is disconnected before performing installation or service.
·Ensure the area around the UPS system is clean and uncluttered.
·Battery maintenance or battery replacement should be performed only by
authorized service personnel.
·Observe all DANGER, CAUTION, and WARNING notices affixed to the
inside and outside of the equipment.

1.1 Installing the UPS
The cabinet sections of the UPS are shipped on separate pallets. Use a forklift or
pallet jack, rated to handle the weight of the cabinets (refer to Drawing
164201244---3 in Appendix A for cabinet weights), to move the packaged cabinet
sections to the installation site, or as close as possible to the site, before unloading
from the pallet.
This is the basic sequence of the installation steps:
1. Create an installation plan for the UPS system (Chapter 1).
2. PrepareyoursitefortheUPSsystem(Chapter1).
3. Inspect, unpack, and unload the UPS cabinet sections (Chapter 1).
4. Wire the system (Chapter 2).
5. Install features, accessories, and/or options, as applicable (Chapter 3).
6. Complete the Installation Checklist (Chapter 2).
7. Have authorized service personnel perform preliminary operational checks and
startup.
NOTE: Startup and operational checks should be performed only by authorized
service personnel. This service is usually offered as part of the sales
contract for your UPS. Contact service in advance (usually a two week
notice is required) to reserve a preferred startup date.
1.1.1 Creating an Installation Plan
Before beginning to install the UPS system, read and understand how this manual
applies to the system being installed. Use the procedures and illustrations in the
following chapters to create a logical plan for installing the system.
1.1.2 Preparing Your Site
For your UPS system to operate at peak efficiency, your installation site should
meet the environmental parameters outlined in this manual. If you intend to
operate the system at an altitude higher than 1500 meters (5000 feet), contact your
local sales or service office for important information about high altitude operation.
The operating environment must meet the size and weight requirements shown in
Drawing 164201244---8, and Table P of Appendix A.

164201244 REV. D 030101
The basic environmental requirements for operation of the UPS system are:
Ambient Temperature Range: 0 --- 4 0 ˚C (32---104˚F)
Recommended Operating Range: 20---25˚C (68---77˚F)
Maximum Relative Humidity: 95%
The UPS cabinets use forced air cooling to regulate internal component
temperature. Air inlets are in the front of the cabinet, and outlets are in the top.
You must allow clearance in front of and above each cabinet for proper air
circulation.
1.1.3 Environment Considerations
The life of the UPS system is adversely affected if the installation does not meet the
following guidelines:
1. The system must be installed on a level, sealed concrete pad or on a sealed
concrete floor.
2. The system must be installed in a temperature-controlled indoor area free of
conductive contaminants.
Failure to follow guidelines may invalidate UPS warranty.
1.1.4 Preparing for Wiring the UPS System
For external wiring requirements, including the minimum AWG size of external
wiring, refer to Table A or B in Appendix A. The power wiring connections for this
equipment are rated at 90˚C. Ifwireisruninanambienttemperaturegreaterthan

wiring for EPO and optional accessories (such as building alarms, and monitoring
interface) should be connected at the customer interface panels and terminal
blocks located inside the UPS.
