ntroduction

Powerware 9335 UPS true double conversion 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 UPS System continuously 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. During brownouts, blackouts and other power
interruptions, optional battery strings provide emergency power to safeguard your
operation.

The UPS system is housed in free-standing cabinets. The cabinet sections are
matching in design and color, and have safety shields behind the front panels for
hazardous voltage protection. The following illustration depicts a typical Powerware
9335 (80 kVA and 120 kVA) UPS System.

Safety Considerations

y

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 the 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 s

If service or routine maintenance is required:

1.1 Installing the UPS

The complete UPS cabinet is shipped on a single pallet. Use a forklift or a pallet jack, rated
to handle the weight of the cabinets (refer to Table J in Appendix A for cabinet weights) to
move the packaged cabinet 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. Prepare your site for the UPS system (Chapter 1)

3.

Inspect, unpack, and unload the UPS cabinet. (Chapter 1)

4.

Wire the system. (Chapter 2)

5. Install features, accessories, and/or options, as applicable. (Chapter 4 and 10)

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 service contract for your
UPS. Contact Global Services 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.

Powerware 9335 (80 kVA and 120 kVA) Installation and Operation 1-1
164201396 REV A 071103

1.1.2 Preparing Your Site

For your UPS 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 weight, airflow, size and clearance requirements specified in Appendix A.

The basic environmental requirements of the UPS system are:

Maximum Relative Humidity: 95% (non-condensing)

The UPS cabinet uses forced air cooling to regulate internal component temperature. Air
inlets are in the bottom sides and front of the cabinet, and outlets in the top of the cabinet.
You must allow clearance in back of the cabinet for proper air circulation. Refer to Table K
of Appendix A for clearance requirements.

Ambient Temperature Range:

Recommended Operating Range:

0 – 40˚C (32 – 104˚F)

20 – 25˚C (68 – 77˚F)

1.1.3 Environmental 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 floor suitable for computer or electronic

equipment.

2. The system must be installed in a temperature-controlled indoor area free of conductive
contaminants.

Failure to follow guidelines may invalidate the 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 Tables A and B in Appendix A for the Powerware 9335 (80 kVA and 120 kVA) UPS. The
power wiring connections for this equipment are rated using copper wire at 90˚C. Note that
wiring to an external battery cabinet may be either 75˚C or 90˚C rated. Control wiring for
EPO and optional accessories (such as building alarm and monitoring interface) should be
connected at the customer interface connections inside the front of the UPS using class 1
wiring methods.

Understanding UPS Operation

5.1 Looking Inside the UPS System

The Powerware 9335 is a continuous duty, solid-state, transformerless (at 480 VAC) three
phase, true online system that provides conditioned and uninterruptible AC power to the
UPS systems output. The UPS supports process control, data processing,
telecommunications/PBX, and research equipment. The Powerware 9335 maintains power
to the critical loads during commercial electrical power brownout, blackout, overvoltage,
undervoltage and out-of-tolerance frequency conditions.

The basic system consists of a:

• rectifier

• battery charger

• DC booster

•

Inverter

•

monitoring/operation control panel

•

integrated communications server

•

microprocessor controlled logic

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 5–1 shows the main elements of the UPS.

Fig. 5–1. Main Elements of the UPS System

If utility power is interrupted or falls outside the parameters specified in Chapter 13, “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 UPS is designed to operate with an alternative power system (such as a generator) or
will shut down your critical load in an orderly manner, if Powerware shutdown software is
used.

In the event of a severe output overload or failure of a critical internal UPS component, an
emergency bypass, consisting of a continuous duty static switch, and backfeed protection
contactor (K4) is utilized. The backfeed protection contactor is located in series with the
static switch, to ensure safety to anyone working upstream of the UPS system. For manual
transfers to bypass, the static switch is also used. The static switch is armed and ready
during both types of transfers.

If maintenance of the UPS system is required, an internal Maintenance Bypass switch
provides a means of isolating the UPS Rectifier/Booster/Inverter components for servicing,
while still supplying power to the critical load.

The operation of the UPS is described in greater detail in the following paragraphs.

5.2 Normal, Battery and Bypass Modes

The UPS system functions automatically to supply AC electrical power to the critical load.
There are four standard operation modes.

•

• In Battery mode, the critical load is supplied by the inverter which derives its

•

•

The UPS continually monitors itself and the incoming utility power, and automatically
switches between these modes as required, with no operator intervention, except for the
Maintenance Bypass mode. The sophisticated detection and switching logic inside the
UPS ensures that operating mode changes are automatic and transparent to the critical
load.

System events are alarms and notices that are displayed on the LCD monitor panel.
They may or may not require operator intervention. See Chapter 9.

The following descriptions provide the differences in UPS operating 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 battery charger also
provides charging current for the battery, if needed.

power from the battery DC power.

In Bypass mode, the critical load is directly supported by utility power via the
static switch. In this mode, the critical load is not protected.

In Maintenance Bypass mode, the critical load is directly supported by utility
power, but the UPS can be shut down for maintenance. The operator switching
the Maintenance Bypass Switch to the Bypass position accomplishes this,
however, the critical load is not protected.

Figure 5–2. Path of Current Through the UPS in Normal Mode

During normal UPS operation, power for the system is derived from a utility input source
through the input contactor K1 (and externally protected utility feed). “Load Protected”
appears on the LCD display and indicates the incoming power is within voltage and
frequency acceptance windows. Three phase AC input power is converted to DC using a
full-wave, six-pulse, solid-state rectifier block which supplies unregulated DC voltage to a
boost converter which in turn supplies a higher, regulated DC voltage to the inverter.

A separate internal battery charger is used to maintain the proper charge level on the
battery during normal operation. The battery charger derives its input from the booster
output and provides regulated DC voltage and charge current to the battery. The battery
charge condition is monitored by the UPS and, when abnormal, reported by the status
indicators located on the LCD display. The battery is always connected to the UPS and
ready to support the inverter should the utility input become unavailable.

IA2

5-4 Powerware 9335 (80 kVA and 120 kVA) Installation and Operation

164201396 REV A 071103

The DC boost converter derives power from the unregulated DC rectifier and produces a
higher, stable DC voltage and current source for the inverter. A fixed system neutral is also
carried through the boost converter to allow full support of single phase AC loads from any
phase of the inverter output. The output neutral of the system is connected to the required
neutral, both from the main utility supply and the bypass supply and should never be bonded
to protective earth ground at the UPS output.

The inverter produces three phase AC power to a customer load without the use of a
transformer. The inverter derives power from the boost converter regulated DC and utilizes
IGBT devices and pulse-width modulation (PWM) to produce a regulated and low harmonic
content AC output. The AC output of the inverter is delivered to the system output through
the output contactor K2.

If the utility AC power is interrupted or is out of specification, 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 overload condition is cleared and
system operation is restored within specified limits.

If the UPS experiences 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.

164201396 REV. A 071103

5.2.2 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 5–3 shows the path of electrical power through the UPS system when operating in
the Bypass mode.

Figure 5–3. Path of Current Through the UPS in Bypass Mode

In BYPASS mode, the output of the system is provided with three phase AC power directly
from the systems input. While in this mode, the output of the system is not protected from
voltage or frequency fluctuations or power outages from the source. Some power line
filtering and spike protection is provided to the load but no active power conditioning or
battery support is available to the output of the system in the bypass mode of operation.

The internal bypass is comprised of a solid state silicon controlled rectifier (SCR) static
switch (SSW), and a back feed protection contactor (K4). The static switch is rated as a
continuous duty device that is used anytime the boost converter and inverter is unable to
support the applied load. The static switch is wired in series with the back feed protection

5-6 Powerware 9335 (80 kVA and 120 kVA) Installation and Operation

164201396 REV A 071103

contactor and together are wired to enable the inverter and rectifier to be bypassed when
this path is active. The static switch, as an electronically controlled device, can be turned on
immediately to pick up the load from the inverter. The backfeed protection contactor is
normally always closed, ready to support the static switch unless the bypass input source
becomes unavailable.

During an outage, transfers to bypass are prohibited and for the safety of those who may be
working on the power lines upstream from the UPS, the back feed protection contactor is
opened, preventing system output voltage from bleeding across the static switch snubber
components to the bypass input source. In the bypass mode, which can be used for higher
efficiency operation, the static switch is turned on to supply the load current directly from the
bypass supply, with the inverter ready to take over the load if the bypass supply should vary
outside preset limits.

If the inverter is unable to support the load on the output of the system, the UPS will transfer
the critical load to the internal bypass. The critical load will be transferred automatically to
the internal bypass if any of the following abnormal conditions occur on the output of the
system: If the output of the system exceeds acceptable voltage tolerances; Critical load
current exceeds the overload specifications of the inverter; Inverter failure. The transfer is
initiated by turning on the static switch and blocking the IGBT gate signal. This kind of
transfer is normally referred to as a Make-Before-Break transfer. The transfer takes place in
less than 4 ms (one-quarter cycle) to ensure loads on the systems output are not
interrupted. The static switch remains on until either the inverter is able to support the
system output or the unit is placed into a maintenance position where repairs can be made.

If the UPS initiates its own transfer to bypass for any reason other than operator
intervention, the UPS will attempt to restart the inverter (if not running already) and attempt
a retransfer back on line to support the output of the system. Three attempts will be made
within ten minutes to bring the inverter back on-line automatically before the UPS will lock
out any further attempts. After three attempts have been made, the UPS will remain in
bypass and an alarm condition will be annunciated. The UPS can also be transferred to
bypass using the front panel controls.

Bypass mode is a normal operating mode, not requiring 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.

5.2.3 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.

During a utility power failure, the rectifier no longer has an AC utility source from which to
supply the DC output current required to support the battery charger and boost converter.
The input contactor (K1) is opened, the battery charger is turned off, and the battery SCRs
(+ and -) both receive signals to turn on to provide battery power to the system. Because
the battery SCRs are electronic devices, battery power is instantly available to the boost
converter so that the inverter and customers load can be supported without interruption. In
a single feed installation, where the bypass input is connected to the rectifier input, the back
feed protection contactor (K4) will also open. The opening of contactors K1 and K4
prevents static system voltage from bleeding backwards through the static switch and
rectifier snubber components and re-energizing the input source.

5-8 Powerware 9335 (80 kVA and 120 kVA) Installation and Operation

164201396 REV A 071103

While in battery mode, the UPS will enunciate an audible horn, indicate the status change
on the front panel display with the message “MAINS NOT OK”, and make an entry into the
alarm event history. As the battery discharges, the boost converter and inverter constantly
make small adjustments to ensure a steady output. The UPS will remain in this operating
mode until the input power to the rectifier is again within the specified voltage or frequency
acceptance window.

If the input power fails to return or is not within the acceptance parameters required for
normal operation, the battery will continue discharging until a DC voltage level is reached
where the inverter output can no longer support the connected loads. When this occurs, the
unit will issue another set of audible and visual alarms indicating “BATTERY IN
DISCHARGE”. Unless the rectifier has a valid input soon, the critical load will only be
supported for about 3 minutes before the output of the system shuts down completely.
When this occurs, the LCD display will show the message “BATTERY DISCHARGED”.

If at any time during the battery discharge, the input power becomes available again,
contactors K1 and K4 are closed and the rectifier will begin to supply DC current to the
boost converter and inverter. The battery SCRs will be switched off while the battery
charger is turned back on to begin recharging the battery. At this point, the unit returns to
normal operation.

The systems total operating time on battery will depend on many factors. Some factors that
affect battery support times are battery type and capacity, number of parallel strings,
environmental temperatures, age of the battery, and fluctuations in load demand during the
discharge. The greater the load, the less support time the battery will provide. Decrease
the load and the battery support time will generally increase.

164201396 REV. A 071103

5.2.4 Maintenance Bypass Mode

An internal maintenance switch (IA1) is used to safely supply utility power to the system
output during periods of maintenance or repairs. Before this switch is used, the system
should be transferred to bypass. This switch has two positions: “O” (OFF) and “l” (ON).
When switched to “l” (ON), the bypass source supplies the commercial AC power to the
load directly.

While on internal (static) bypass, when a user rotates the maintenance switch from the
“O” (OFF) to the “l” (ON) position, the load is wrapped around the UPS, and power is
removed from the entire upper portion of the UPS allowing service work to be completed
on the UPS safely.

Figure 5–5 shows the path of electrical power through the UPS system when operating
in Maintenance Bypass mode.

CAUTION:
The critical load is not protected while the UPS is in the Maintenance Bypass
mode.

DANGER:
LETHAL VOLTAGE PRESENT: This unit should not be operated with the
cabinet doors open or protective panels removed. Do not make any
assumptions about the electrical state of any cabinet in the UPS system.

Functional Description

5.3

The UPS is an online double-conversion unit with a series power train. An uncontrolled
rectifier feeds a boost converter, which in turn powers the inverter. The internal static
bypass utilizes a static switch and an independent maintenance bypass switch is also
included internal to the UPS cabinet. The unit input must be 4-wire in (plus ground) at
the rectifier and 4-wire in (plus ground) at the bypass. The output can be either 4-wire
plus ground or 3-wire plus ground depending on customer requirement. The unit does
not incorporate any galvanic isolation, input to output. The battery string comprises 240
cells (480 volts nominal) arranged in a positive string of 120 cells and a negative string
of 120 cells with the center of the series connected strings tied to system neutral, for the
80 kVA model. The 120 kVA model utilizes 144 cells on each side of the center
connection (nominal 288 volts positive and negative, for 576 volts total). The battery is
charged by positive and negative side chargers, which are powered from the output of
the boost converter.

5.3.1 Input Rectifier

The Input Rectifier is a full wave bridge uncontrolled rectifier, which produces
unregulated DC of approximately +390 and –390 volts DC. A pre-charge system
charges the DC bus prior to the input contactor being closed, to control inrush current to
no higher than rated current levels.

5.3.2 Boost Converter

A Boost Converter converts the raw DC input to a regulated DC link voltage of
approximately +450 and –450 volts DC. It is operated in the current mode and is
controlled using a variable modulation technique with a frequency in the range of
20 kHz. The neutral connection is maintained from the input to the output as a fixed
connection.

5.3.3 Inverter and Filter

The inverter is a traditional (current mode controlled) hard-switched IGBT 3-phase
topology. The IGBTs are modulated by a variable frequency, current-mode control
technique at approximately 20 kHz. An output filter filters out the high frequency
switching components (line to neutral).

5.3.4 Batteries and Battery Charger

The battery for the Powerware 80 kVA system is comprised of a positive string of 120
cells and a negative string of 120 cells, each made up of twenty 12-volt battery blocks.
For the Powerware 120 kVA system, the battery strings are 144 cells positive and
negative, respectively. The battery charger is divided into a positive side charger and a
negative side charger, each powered from the respective positive and negative
controlled DC bus voltages. The chargers operate automatically in the constant current

Powerware 9335 (80 kVA and120 kVA) Installation and Operation 5-11
164201396 REV. A 071103

or constant voltage mode (temperature compensated, available as an option) based on
battery condition.
All batteries used in conjunction with the Powerware 9335 are external to the UPS
cabinet. The internal charger charges the entire battery system, with a maximum current
as indicated in Chapter 13, “Product Specifications”. Note that the higher the battery
capacity, the longer the recharge time required to fully recharge the batteries.

5.3.5 Static Bypass

The bypass has a continuous-duty SCR switch and a back-feed contactor (K4) in the
Bypass circuit. In normal mode, the contactor connects the inverter to the output. A
contactor (K2) provides isolation to the inverter when the system is on bypass.

5.3.6 Maintenance Bypass

A user accessible shrouded 4-wire Mechanical Maintenance Bypass switch is provided
internal to the cabinet.

LINE 1 INV.

Using the control panel (see Figure 7–2) the UPS can easily be transferred to the ON­LINE mode. The ON-LINE mode provides the highest degree of protection, especially in
the event of a supply disturbance or failure. This operating mode is always
recommended if the critical loads (computer systems) will not tolerate any interruption of
the supply, even for a very short time. In the unlikely event of an inverter fault or
overload condition, the UPS will transfer the load automatically and without interruption
to the static bypass-utility supply.

7.4.2 “OFF LINE” Mode (BYPASS or ECONOMY MODE)

In the OFF-LINE mode, the load is supplied from the utility supply through the bypass.
Using the control panel (see Figure 7–2), the UPS may be easily transferred to “Bypass
Mode”.

7.4.4 Parallel Isolator (IA2)

The UPS unit is provided with an output isolator switch (IA2) which, when opened,
isolates the corresponding unit from the LOAD. Once IA2 is open, there is no power
coming from the inverter. This switch should always be in the “I” (ON) position, except
for servicing the UPS when in the maintenance bypass mode. Rotating this switch to the
“O” (OFF) position while the inverter is supplying power to the load will dump the critical
load. This switch is also provided for future expansion requirements.

The generator ON facility must use a normally open contact that closes to indicate that a
generator is running and supplying input power to the UPS. When used, this facility
disables the UPS static bypass and prevents the UPS from transferring the load into the
generator power supply. The user may also elect prevention of battery charging while
on generator input. Both or either of these features may be selected via the control
panel. (See section 7.3.8, Set Up)

aintaining the UPS System

12.1 General

The components inside the UPS cabinet are secured to a sturdy metal frame. All
repairable parts and assemblies are located for easy removal, and very little
disassembly. This design allows authorized service personnel to perform routine
maintenance and servicing quickly.

You must schedule periodic performance checks of your UPS system to keep it running
properly. Regular routine checks of operation and system parameters will enable your
system to function efficiently for many trouble-free years.

12.2 Important Safety Instructions

Remember that your UPS system is designed to supply

DISONNECTED FROM THE UTILITY POWER.

until the DC power source is disconnected and all capacitors are discharged. After
disconnecting the utility power and the DC power, authorized service personnel should
wait at least 5 minutes for capacitor bleed off before attempting internal access to the
UPS cabinet.

WARNING:
Servicing and maintenance should be performed only by qualified service
personnel.

DANGER:
LETHAL VOLTAGE PRESENT: This unit should not be operated with the cabinet
doors open or protective panels removed. Do not make any assumptions about
the electrical state of any cabinet in the UPS system

Since each battery string is an energy source in itself, opening the Battery Circuit
Breaker does not de-energize the voltage within the battery string. DO NOT ATTEMPT
TO ACCESS ANY INTERNAL AREA OF THE BATTERY STRING YOURSELF.
VOLTAGES ARE ALWAYS PRESENT IN THE BATTERY STRING. If you suspect that
a battery string needs service, you should contact your local field service office.

12.3 Performing Preventive Maintenance

The UPS system requires very little preventive maintenance. However, the system
should be inspected periodically to verity that the units are operating normally and that
the batteries are in good condition.

Perform the following checks DAILY:

1.

Check the area surrounding the UPS system. Ensure the area is not cluttered,
allowing free access to the unit.

2.

Ensure the air intakes (vents on the bottom) and exhaust opening (on the top of the

cabinet) are not blocked.

3.

Ensure the operating environment is within the parameters specified in Chapter 13,

“Product Specifications.”

4. Ensure the UPS is in Normal mode. (Proper LED indicators are illuminated and the
LCD display shows “LOAD PROTECTED”). If the alarm LED is illuminated or the
Normal status LEDs are not illuminated, contact Customer Service.

Perform the following check MONTHLY:

1.

Review the Event Log for any operational issues that need attention.

ANNUAL maintenance:

Annual preventive maintenance should be performed only by authorized service
personnel familiar with maintenance and servicing of the UPS system. Contact your
nearest field service office for more information about service offerings.

BATTERY Test:

The battery test takes approximately 3 minutes and should be performed only if:

• There are no alarm conditions

•

•

The battery testing can be carried out independently of the operation mode (OFF-LINE
or ON-LINE) and whether or not the load is connected. The battery test procedure can
be performed from the UPS front panel. See Chapter 7, “Using the Control Panel”.

BATTERY Maintenance:

Contact your nearest field service office for battery maintenance. Only authorized
service personnel should perform Battery replacement and maintenance.

LIMITED FACTORY WARRANTY FOR THREE-PHASE POWERWARE PRODUCTS

Subject to the conditions herein, Invensys Powerware (Powerware ®) warrants solely, to the original end-user, the
electronics (the “Unit”), and Powerware built battery cabinets, against defects in material and workmanship for the
warranty period of 12 months, from the date of equipment start up, or 18 months from date of shipment, whichever
occurs first. Should service be necessary, this warranty covers:

USA only: The Powerware 9315, 9330, 9335 three-phase UPS products are sold with a standard factory

warranty (described below), start up, and extended labor service. All three-phase UPS
installations will have an authorized Invensys Powerware Service Engineer or Agent perform
startup or the factory warranty and extended labor service will be void. The included first year
extended labor service provides for a complete 12 months of onsite labor for your UPS purchase.

Worldwide: All parts requiring replacement for the Factory Warranty period.

If, in the opinion of Invensys Powerware, the Unit fails to meet published specifications and the defect is within the
terms of this warranty, the Unit will be repaired or replaced at the option of Invensys Powerware with no charge for
replacement parts. Labor required, to make upgrades, repairs or replacement installation, is not included under the
terms of this Limited Warranty, except for labor and travel costs required during the first 90 days of this warranty
(USA only), provided that startup of the unit onsite, has been performed by Invensys Powerware or its agent.
Equipment sold, but not manufactured by Invensys Powerware, and only the manufacturer of such equipment shall
warrant this equipment and is not included as part of this warranty agreement. Equipment repaired or replaced
pursuant to this warranty will be warranted for the remaining portion of the original warranty subject to all the terms
thereof.

This warranty is not valid unless an authorized Invensys Powerware Service Engineer or Agent performs startup and
commissioning. This warranty does not apply to any Unit that has been subject to neglect, accident, abuse, misuse,
misapplication, incorrect installation, or that has been subject to repair or alteration, not authorized in writing by
Invensys Powerware personnel or performed by an authorized Invensys Powerware Service Engineer or Agent.
Purchaser shall be invoiced for, and shall pay for, all services not expressly provided for by the terms hereof,
including, without limitation, site calls involving an inspection that determines no corrective maintenance is required.
THIS WARRANTY IS THE PURCHASER’S (USER’S) SOLE REMEDY AND IS EXPRESSLY IN LIEU OF, AND
THERE ARE NOT OTHER, EXPRESSED OR IMPLIED GUARANTEES OR WARRANTIES (INCLUDING ANY
IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE, WHICH ARE EXPRESSLY
DISCLAIMED). In no case will Invensys Powerware’s liability under this Warranty exceed the replacement value of
the Unit warranted.

Invensys Powerware’s obligation, under said warranty, is expressly conditioned upon receipt by Invensys Powerware
of all payments due it (including interest charges, if any). During such time as Invensys Powerware has not received
payment of any amount due it, in accordance with the Contract terms under which the equipment is sold, Invensys
Powerware shall have no obligation, under said warranty; also during this time, the period of said warranty shall
continue to run and the expiration of said warranty shall not be extended upon payment of the overdue amount.
These limitations, to said warranty, apply even in the event that the equipment is sold initially by Invensys Powerware
for resale to an ultimate end-user.

In no event shall Invensys Powerware be liable for any indirect, incidental special or consequential damages of any
kind or type whatsoever, or based on any claim or cause of action, however denominated. Invensys Powerware shall
not be responsible for failure to provide service or parts due to causes beyond Invensys Powerware’s reasonable
control. This limited warranty applies only to the original end user of the unit.

This factory warranty will not be in effect if the End-User does not properly store the equipment, including the “trickle
charge” of batteries no later than the date indicated on the packaging, before installation and does not cover shipping
damages if FOB Factory. Cost for replacement equipment, installation, material freight charges travel expenses and
labor of Invensys Powerware representatives will be borne by the Purchaser (user). Any advice furnished the
Purchaser before or after delivery in regard to use or application of Powerware equipment is furnished without charge
and on the basis that it represents Invensys Powerware’s best judgment under the circumstances. The use of any
such advice by the Purchaser is solely and entirely at its own risk. Any other agreements, such as Service contracts
or Sales Concessions are not means to annul this Factory Warranty.

For comment or questions, about this Limited Factory Warranty, write to the Customer Quality Representative, 3301 Spring Forest
Road, Raleigh, NC 27601, or call (919) 872---3020
