Powerware 9315 (500 kVA--750 kVA) Installation and Operation
164201244 REV. D 030101
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.

Getting Started
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.

9.1 Looking Inside a Parallel Capacity/Redundant System
The Powerware 9315 is a continuous duty, solid-state UPS that supports the
following equipment: process control, data processing, telecommunications/PBX,
research, and medical. The Powerware 9315 maintains power to the critical loads
during commercial electrical power brownout, blackout, overvoltage, undervoltage,
and out-of-tolerance frequency conditions.
In this manual, the power required by your equipment is called the critical load.The
UPS supplies the critical load with conditioned power that is synchronized with your
utility power. Figure 9 ---1 shows the main elements of the UPS.

The emergency bypass consist of a static switch, a wraparound bypass breaker
(CB4) and a backfeed protection breaker (FBP). The backfeed protection breaker
is located in series with the static switch. If an SCR shorts, the breaker opens so
that the UPS cannot backfeed the bypass source.
For manual transfers to bypass, the static s witch is not used. During the transfer,
CB4 is closed and verified and then inverter output breaker CB3 is opened. For
transfers of the load from bypass to the UPS, CB3 is closed and verified and then
CB4 is opened. The static switch is armed and ready during both types of
transfers.
If utility power is interrupted or falls outside the parameters specified in Chapter 18,
“Product Specifications,” the UPS uses a backup battery supply to maintain power
to the critical load for a specified period of time or until the utility power returns.
For extended power outages, the backup battery supply allows you to either
transfer to an alternative power system (such as a generator) or shut down your
critical load in an orderly manner.
9.2 Normal, Battery, and Bypass Modes
The UPS system functions automatically to supply AC electrical power to the critical
load. There are three standard operation modes:
· In Normal mode, the critical load is supplied by the inverter, which derives its power
from rectified utility AC power. In this mode, the rectifier also provides charging
current for the battery.
· In Battery mode, the battery cabinet provides DC power, which maintains inverter
operation. The battery supports the critical load.
· In Bypass mode, the critical load is directly supported by utility power.
The UPS continually monitors itself and the incoming utility power, and
automatically switches between these modes as required, with no operator
intervention. The sophisticated detection and switching logic inside the UPS
ensures that operating mode changes are automatic and transparent to the critical
load. The UPS switches operating modes in response to these system events:
· A command is an intervention that is externally initiated by an operator or by some site
action. A command causes the UPS to switch operating modes; it usually does not
require any further action by you.
· A notice is a minor system event that may or may not require your attention.
· An alarm is a system event that requires immediate operator intervention.
System events, alarm horns, and indicator lights are described in Chapter 14,
“Responding to System Events.”
The following descriptions provide the differences in UPS operating modes.
9--2
Powerware 9315 (500 kVA--750 kVA) Installation and Operation
164201244 REV. D 030101
9.3 Normal Mode
In Normal mode, utility AC power is supplied to the rectifier. The rectifier supplies
DC power to the inverter, which then supplies the critical load with AC power. The
rectifier also provides charging power to the battery. The battery charge condition
is monitored by the UPS and reported by a status indicator on the Control Panel.
The message “System Normal” appears in the status area of the Control Panel
LCD screen.
Figure 9--- 2 shows the path of electrical power through the UPS system when the
UPS is operating in Normal mode.

If the utility AC power is interrupted or is out of s pecification, the UPS automatically
switches to Battery mode to support the critical load with no interruption. When
utility power returns, the UPS returns to Normal mode.
If the UPS becomes overloaded or unavailable, the UPS switches to Bypass mode.
The UPS automatically returns to Normal mode when the error condition is cleared
and system operation is restored within specified limits.
If the UPS suffers an internal failure, it switches automatically to Bypass mode and
remains in that mode until the failure is corrected and the UPS is back in service.

9.4 Bypass Mode
The UPS automatically switches to Bypass mode if it detects an overload, load
fault, or internal failure. The bypass source supplies the commercial AC power to
the load directly.
Figure 9---3 shows the path of electrical power through the UPS system when
operating in Bypass mode.

TheUPScanbetransferedfromNormalmodetoBypassmodemanually.
However, the UPS switches automatically to Bypass mode whenever the inverter
can no longer supply the critical load. Initially, the static switch fires and conducts
power from breaker FBP to the load. When breaker CB4 closes, the static switch
stops conducting and breaker FBP opens. If the UPS transfers to Bypass mode
from Normal mode due to any reason other than operator intervention, the UPS
automatically attempts to transfer back to Normal mode (up to three times within a
10-minute period). The fourth transfer locks the critical load to the bypass source
and requires operator intervention to transfer.
Bypass mode is a normal operating mode, and not an alarm condition. However, if
the UPS is unable to return to Normal mode following an automatic transfer to
Bypass mode, an alarm condition is recorded.

164201244 REV. D 030101
9.5 Battery Mode
The UPS transfers to Battery mode automatically if a utility power outage occurs,
or if the utility power does not conform to specified parameters. In Battery mode,
the battery provides emergency DC power that the inverter converts to AC power.
When the UPS switches to Battery mode, the alarm indications depend on the
cause and condition of the battery charge. The length of time the system can
operate in Battery mode depends on loading and the battery supply capacity.
Figure 9---4 shows the path of electrical power through the UPS system when
operating in Battery mode.

When the discharging battery voltage reaches the lower limit of UPS operation
capability, the critical load transfers to Bypass mode if it is available. If Bypass input
is not available, a “Shutdown Imminent” warning occurs. The warning time before
critical load loss occurs is approximately 2 minutes, depending on battery capacity
and the amount of loading.
If incoming power returns to within specified parameters, the UPS automatically
returns to Normal mode and alarm indications clear. However, the process of returning
to Normal mode is not instantaneous. The rectifier gradually draws increasing power
from the incoming utility until Normal mode is achieved.

10.2.2 UPS Circuit Breakers
The UPS can contain as many as four circuit breakers, the UPM Input Breaker
(CB1), the UPS Output Breaker (CB3), the System Bypass Breaker (CB4), and the
Backfeed Protection Breaker (FBP).
CB1 controls the input to the UPS rectifier, while CB3 controls the output of the
UPS inverter. CB1 is optional and may be either motor operated or manual
controlled.
CB4 and the FBP are used in single module applications and are contained in the
Module Bypass section of the UPS. CB4 is used as the bypass supply in the event
the output of the UPS is not available and to supply the critical load during
maintenance. The FBP is used to prevent power feedback to the UPS input supply
when the UPS is operating in the battery mode. These breakers are electrically
controlled by the UPS and are automatic in operation.
Multi-module systems replace the Module Bypass section of the UPS with a
System Bypass Module (SBM). Refer to the applicable SBM Installation and
Operation manual referenced in the Introduction of this manual for SBM circuit
Breakers.
In addition, a remote mounted external battery disconnect is used to connect the
battery string to the UPS. This disconnect is manually operated.
10.2.3 EMERGENCY UPM OFF
An EMERGENCY UPM OFF pushbutton is provided for situations where you must
instantaneously control the UPS output. The pushbutton is located on the front of

Using Features and Options
13.1 General
The many standard features of your UPS system provide consistent, economical,
and dependable power protection. In addition, you can add available options to
enhance the performance of your system. This chapter provides descriptions of
some of the features and options introduced earlier in this manual. Refer to
drawings 164201244---1, 164201244---2, and 164201244 ---7 in Appendix A for
location of the customer interface panel and terminals and for terminal wiring
information.
13.2 Building Alarm Monitoring
This standard feature lets you connect the UPS to your building alarms, such as
smoke detectors or overtemperature alarms. The customer interface terminals for
external connections are located inside the UPS.
Regardless of how you assign the building alarms, they display as Building Alarm
1, Building Alarm 2, Building Alarm 3, etc., on the LCD screen of the Monitor Panel.
You should use twisted pair wires for each alarm input and common.
13.3 General Purpose Relay Contacts
13
Two general purpose relay contacts are provided as a standard feature on the UPS.
The alarm contacts (one notice and one alarm) are located inside the UPS on the
customer interface terminal board.
You can specify that each contact be either normally closed (NC) or normally open
(NO). If the state of the contact changes from the state you specify as normal, an
signal is issued. You can connect these contacts to equipment at your facility
(such as a light or an alarm bell) to let you know when an alarm is active on the
UPS. This feature is useful if the UPS is located in a remote area where the UPS
alarm horn may not be heard immediately.
CAUTION:
Contacts should not be operated in excess of 30 VAC or 42.4V peak AC or DC
@1Amaximum.

Responding to System Events
14.1 General
When the UPS system is running in Normal mode, it continually monitors itself and
the incoming utility power. In Battery or Bypass modes, the UPS may issue alarms
to let you know exactly what event caused the change from Normal mode. System
events on the UPS can be indicated by horns, lights, messages, or all three.
Select Active from the Events menu on the LCD screen to look at the Active
System Events screen. This screen shows any currently active alarms, notices,
or commands.
14.2 System Event Horns
The system event horn beeps according to the type of event it is signifying:
· When the UPS detects an alarm that requires your attention, the horn beeps at
½-second intervals.
· When a notice occurs, the horn beeps at 2-second intervals.
14.3 System Event Lights
14
The status indicators on the UPS Control Panel work in conjunction with the event
horn to let you know when the UPS system is operating in any mode other than
Normal. Only the Normal indicator is visible during normal UPS system operation.
The others light to indicate alarms or events. When an alarm occurs, you should
first check these indicators to see what type of event has taken place. (For
descriptions of the status indicators, refer to the “Reading the S tatus Indicators”
section of Chapter 11.)
