1. Cabinets should always be stored in an upright position. Failure to observe this precaution can cause serious damage and
cancellati on of war ranty.

2. Cabinets should be forklifted only at appropriate lifting points. Make sure that forks are long enough to go entirely under the unit
and protrude from the oth er side. Be careful not to pun c t ure another unit beyond the one being lifted.

3. Chains, cables, ropes or oth er retaining devices sh ould not be wr apped around a cabin et. The weight of th e system is great
enough to cause collapse of the cabinet when lifted by these means.

4. Pa dding mus t be us ed when transporting the system s o a s to help prevent damage to the cabi n ets.

Inspection and Unpack ing Instructions:

The uninterruptible power system (UPS), battery pack cabinet and/or power distribution unit (PDU) is thoroughly checked, both
electrically and mechanically, before shipment from the factory. With the exten sive protection provided in packaging the unit for
shipm ent, it shoul d be in proper cond ition upon recei pt. However, there i s a possibility that the unit might have been damaged in
tran sit so a complet e inspection of th e equipment shoul d be made before si gning receipt . As a minimum, the foll owing insp ection
pr oc edures should be e xecut e d as soon as possible after delivery.

Receiving / Unpacking lnspection Checklist

5. Each palletized unit is designed for forklift or lift gate handling. It is recommended that all packaging be left intact until the unit
is in close proximity to its final location to prevent incidental damage during movement.

6. Inspect th e exterior packaging for obvious damage such as punctures or gashes th at are indicative of da mage to the unit. If
eviden ce of dama ge exist s, save th e packag ing materia l for insp ecti on by th e carr ier when a cl ai m is fil ed. Requ est for in sp ection
should be made immediately.

7. Strapping should be cut and the corrugated cap and/or sleeve carefully removed. Remove padding and plastic sheeting. The

SECTION I

Theory of Operation

1.1 General

The BalancedPower Plus® (BP+) Uninterruptible Power System (UPS)
presented in this manual is a solid state, o n-line system designed to provide high
quality, continuously filtered and conditioned ac power to computers, their
peripherals and/or other critical equipment loads. Most commonly, the UPS is
configured as a single, stand-alone unit. Fi fteen (15) power ratings are available
from 10 to 300 kVA. Information contained herein is applicable to all power ratings
except where specified otherwise.

A single UPS is comprised of the following basic components:

Input transformer
Rectifier/Charger
Inverter
Static Bypass Switch
Bypass Breaker
Output Transformer
System Control Logic and Circuitry
Digital Monitoring Panel
Battery
DC Disconnect

A one-line diagram in Section II shows the relationship of these various
components.

1.2 Rectifier/Charger

The UPS input voltage from the utility is fed into the rectifier/charger
(usually referred to as the rectifier) which converts the ac to filtered, regulated dc
voltage. The dc is used to power the inverter and to recharge the batteries as
necessary. The assembly consists of an input circuit breaker, a transformer, and a
solid-state three-phase rectifier designed t o eliminate e ven ordered harmonics. An
optional input filter reduces harmonics caused by rectifier switching. This prevents
the harmonics from affecting utility distribution.

BP+ 10-150
2/95

Page 1.1

SECTION I

Theory of Operation

1.3 Inverter

The inverter changes dc voltage to precision ac voltage through pulse width
modulation (PWM) inversion. Output isolation transformers and an output filter
provide “clean”, computer grade ac which is then sent to the critical load. When
utility power is available, the rectifier supplies power t o the inverter. Should the
utility power fail, the inverter is powered by the batteries for a predetermined length
of time.

1.4 Static Bypass Switch

The static bypass switch connects the UPS bypass input to the load in the
event of the loss of the inverter output or an overload condition. Du ring normal
conditions, the static bypass switch is in the open or disconnected m ode which
isolates the bypass input from the load.

If the inverter output becomes unavailable or exceeds its specified tolerance,
the static bypass switch will close and transfer the load directly to ac power
without interruption. This transfer is automatically inhibited in the event the UP S
bypass input is not within specified tolerance.

As soon as the inverter becomes available, returns to within tolerance or the
overload clears, the static bypass switch will disconnect and retransfer the load to
the inverter. Note, however, that so long as the inverter is out of sp ecification, the
static bypass switch will automatically inhibit retransfer of the load.

1.5 Batteries

The optional battery pack supplies 216 VDC (10-30 kVA) or 360 VDC (37.5­150 kVA) nominal. It can be attached to the UPS module t o form a sing le unit or
may stand alone to accommodate space restrictions. It is the energy reservoir of the
UPS and provides dc power to the inverter in case of loss of UPS input power or
rectifier malfunction. The DC Disconnect (Battery) Circuit Breaker electrically
isolates the battery pack from the UPS module for maintenance purposes and
provides overcurrent protection at the battery output.

BP+ 10-150
2/95

Page 1.2

SECTION I

Theory of Operation

1.5 Batteries (continued)

The rectifier/charger normally provides a maintaining or “float” charge to
the batteries. Following periods of discharge when the batteries have supplied
power to the inverter, the rectifier/charger increases power to the batteries in order
to recharge them.

1.6 Control Logic and Control Circuitry

The control logic and circuitry of the UPS p rovide the operating logic and
system control for all functions ranging from limiting the rectifier/c harger inrush
current by “walking” it in, to maintaining t he inverter output voltage within rigid
specifications, to determining whether or no t the static bypass switch should be
activated. The control logic is, for all practical purposes, the brain of the UPS.

1.7 Digital Monit oring Panel

The UPS is equipped with a standard Digital Monitoring Panel which
selectively monitors critical parameters of the UPS, using bright, easy-to-read
digital LED displays. In addition, detailed instructions guide the operator through
the UPS startup sequences. An alarm history can be called up on these digital
displays when desired.

In the event of an abnormal condition, an au dible alarm sounds and the
corresponding red LED illuminates to identify the condition so that corrective
action can be taken. Alarm Silence and Emergency Power Off pushbuttons are
provided.

This panel is discussed in greater detail in Section III.

SECTION I

Theory of Operation

1.8 Multi-Level Passwords

A password is required to access and make use of the UPS Maintenance
Menu, described in Section 3.6.3. This menu, with five subsections, makes

possible the performance of a variety of maintenance functions including transfer
and retransfer to bypass, password changes and adjustment of time and date.

All passwords may be changed by a person who already kno ws either the
password in question or a higher level password.

Passwords consist of a minimum of 4 characters and a maximum of 9
characters. The numerals 0 through 9 and letters A through F may be employed.

The first character of the password indicates the privilege level of the
password. The higher the privilege level, the more capabi lities that password can
access.

Privilege level 0: No password. Used for the front panel display of

voltages, currents, etc. only. Does not permit any

menus to be accessed.
Privilege level 1: Reserved for future development.
Privilege level 2: Remote operator password. Used to monitor the UPS,

but not to affect transfers and retransfers.
Privilege level 3: Reserved for future development.
Privilege level 4: Operator password. Monitors the UPS as well as

allowing transfers, retransfers, transfer enables,

retransfer enables, reset faults, etc.

SECTION I

Theory of Operation

1.9 Phone Home Alarm Reporting

When this UPS is activated for phone home operation and the UPS sense s

one of several pre-selected alarm conditions, the UPS automatically dials IPM’s
Field Service computer without human assistance and notifies IPM’s Field Service
personnel of a system problem requiring attention.

Important information downloaded during each phone home event includ es:

1) UPS name, ID and serial number, 2) customer ID and phone number and 3)
list of active alarms. You obtain the following benefits from this feature:

a. Immediate field service notification of site power or UPS problems,

even when the UPS is unattended.

b. Increased availability due to reduced mean-time-to-repair with

automatic notification and complete remote diagnostic capabilities.

c. 24-hours per day, 7 days per week monitoring of unmanned facilities

and locations where operators are unfamiliar with the UPS. Often,
service personnel can take steps to solve a UPS problem remotely
before the user is aware that there is a problem.

An internal modem and a dedicated telephone line are required. Phone

Home Alarm Reporting can be activated only with a Field Service level of password.
It is normally done at the time of startup by our Customer Engineer.

1.10 Dial-Back Security

This security feature is provided to insure system integrity. It prevents

“hackers” or other unauthorized persons from intentiona11y or unin­tentionally accessing the UPS database. Anyone calling the UPS must

establish authority through the use of a dial-back password. The unit will
validate this password against up to four passwords stored in non-volatile
memory. One of the passwords will allow direct communication to commence
with the UPS. The other three passwords will have associated telephone
numbers. If one of these three passwords rec eives validation, the UPS logic will
hang up and dial back the phone number associated with that password . When
connection is made, the remote operator must enter the normal privilege level
password for access to the corresponding level of monitoring diagnostics and

SECTION I

Theory of Operation

1.10 Dial-Back Security (continued)

controls. In this way high level security is provided since the remote operator must
know the dial-back and access passwords and be calling from the proper
associated phone number.

An internal modem and a dedicated telephone line are req uired. Dial-B ack

Security can be activated only with a Field Service level of password. It is normally
done at the time of startup by our Customer Engineer. Phone Home Alarm
Reporting and Dial-Back Security can share the same modem and telephone line.

SECTION II
Installation

2.1 General

Your International Power Machines BalancedPower Plus UPS is UL-listed

and designed for installation on the compute r room floor. Its attractive computer­like appearance and quiet operation eliminate any necessity of creating special
facilities to house the UPS and its battery component. Since all modern computer
rooms utilize environmentally controlled conditions, installation in such a locale
will normally suffice to meet the needs of the UPS.

In the event that computer room installation is not practical, the selection of

a location for the UPS is critical to the per formance of the system and to the life
expectancy of its components. Failure to select a site which meets all requirements
specified in this section can result in excessive maintenance problems. For
environmental considerations, please see the Installation Information at the end of
this section.

Operating temperature range for batteries is 0°C to 40°C (32°F to 104°F).

Battery warranty is conditional upon application at or below 25°C (75°F).
Continuous operation above 25°C may reduce or void battery warranty.

The BalancedPower Plus battery pack supplied by International Power

Machines is listed by Underwriters Laboratories only for use with the
BalancedPower Plus UPS.

2.2 Mechanical Preparation of UPS

The UPS can be fully accessed from the front for operation and mainte-

nance. However, during installation the UPS and any accompanying battery
cabinets should be left at least two feet (61 cm) from the wall to allow access to the
rear. If optional top cable entry has been p urchased, an area of at l east three fe et
(91 cm) is required at the right side for installation.

The following steps should be taken, in the order indicated:

Operation

3.1 General

This section contains safety considerations, UPS operational procedures,

and an overview of the monitoring panel and operating controls for th e system.
Prior to operation, ensure that the UPS has been installed correctly as outlined i n
Section II of this manual. Ensure that correct input/out put phase rotation and
battery polarities have been observed. Failure to do so can result i n damage to
the UPS and/or injury to personnel. Operators should be thoroughly familiar
with the contents of this manual and with the location an d function o f all system
controls and indicators.

3.2 Safety Considerations

Safety considerations are divided into several areas which are discussed

below. Refer also to Section IV of this manual, Maintenance, for safety precautions
to be taken whenever operating or working on the UPS.

3.2.1 Cleanliness

Litter or trash of any sort should not be allowed to accumulate in or around

the UPS. Liquid spills or metal objects carelessly dropped or placed can cause
shorts and damage to the system as well as possible injury to personnel. Dirt and
dust accumulating in the UPS air filters can impede air f low, thereby decreasing
the cooling effectiveness of the blowers and possibly resulting in an overtempera­ture shutdown of the system.

3.2.2 Fire

In order to minimize the possibility of a fire and to reduce the extent of any

damage resulting from such an incident, the walls, ceiling and floor of the UPS
room should be constructed of noncombustible materials. A portable carbon
dioxide extinguisher should be located in the UPS room. Personnel involved in
operating and/or maintaining the UPS should be familiar with Class C hazard
fires.

SECTION III

Operation

3.2 Safety Considerations (continued)

3.2.3 Security/Personnel

Access to the UPS should be limited to a minimum of perso nnel. Module

doors should be kept locked. All personnel who operate or maintain the UPS
should be proficient in normal and emergency operational procedures. A refresher
briefing or test at specific intervals is rec ommended to maintain this proficiency.
New personnel should be trained and tested p rior to operating the equipment. A
thorough knowledge of first aid procedures, especially those pertaining to electrical
shock or bums, and the use of carbon dioxide fire extinguishers should be
mandatory.

3.3 Radio Frequency Energy Hazard

WARNING: This equipment generates, uses and can radiate radio

frequency and if not installed and used in accordance with instructions may cause
interference to radio communications. It has been designed to comply with the
limits for Class A computing devices pursuant to Subpart J or Part 15 of FCC
Rules, which are designed to provide reasonable protection against such inter­ference when operated in a commercial environment. Operation of this equipment
in a residential area is likely to cause interference in which case the user at his own
expense will be required to take whatever measures may be necessary t o correct
such interference.

CAUTION

Always be aware that hazardous
voltages may be present with in the

UPS even when the system is
not operating.

Operation

3.4 Digital Monit oring Panel (continued)

3.4.1 Indicator Lights

The Indicator Lights (LED’s), located in the upper part of the panel, are:

• UPS Normal (green) - This indicates that the critical load is being powered

from the inverter. The LED normally is on and, when this is the only L ED lighted
on the panel, it represents a fully normal condition. Other LED’s may also be
lighted simultaneously indicating a problem with the UPS. When this occurs, first
record the alarm(s). Then, depress the ALARM SILENCE button to reset the alarm
circuitry. Any alarm LED’s will go out when the alarm condition is corrected. See
Paragraph 3.4.5 for more details.

If “UPS Normal” flashes slowly, this indicates that a non-critical alarm is

present, and that message will appear on the message screen. Check Alarm
History (Paragraph 3.6.2) to identify the alarm.

• AC Input Failure (red) -The UPS input power has been disrupted or gone

out of specification limits. The system goes to battery power and the alarm sounds,
alerting the operator to a brownout or power failure. When the batteries run down,
the critical load will shut off unless steps are taken to correct the situation or
another source of input power is provided.

• Low Battery Voltage (red) - When the system is operating on battery

power, this LED illuminates to show approxima tely five minutes remains before
the UPS system shuts down. A message screen (shown on Pa ge 3.6) displ ays the
amount of battery run time left. Also, the link (battery) voltage maybe monitored
(See Paragraph 3.4.2.6). Shutdown occurs when the link voltage drops to 178VDC
(15-30kVA) or 297VDC (37.5-300kVA). If utility power can not be restored or an
auxiliary power source be activated, the critical load sh ould be shut down in an
orderly procedure.

• UPS Overload (red) - The load on the UPS output is in excess of 105% of

rated load. If the condition exists for more than a few seconds, enough of the
critical load should be powered down or remo ved to make the indicator go out.
Otherwise, the UPS will shut down and/or transfer to bypass within 15 minutes. If
the indicators are set to latch, the ALARM S ILENCE button must be depressed
twice to clear it.

Operation

3.4 Digital Monit oring Panel (continued)

3.4.1 Indicator Lights (continued)

This condition may occur when the UPS is loaded close to 100% and a large

disk drive or other motor load is started. These loads draw currents many times
their normal level for a few seconds when first started. The UPS is designed to
handle this short overload condition.

• Transferred to Bypass (red) - An indication that the critical load is being

powered directly from the UPS bypass power source. This situation is created
when maintenance personnel want to bypass the UPS throug h the static bypass
switch for routine maintenance or when an abnormal condition exists in the
inverter, such as failure or extended overload. When in this operational mode, the
critical load does not have UPS protection.

• Transfer Not Available (red) - An indication that transfer to the static

bypass switch is not possible. This may be caused by the UPS bypass input power
source being out of specification or a power outage.

• Battery Not Available (red) - The battery’s DC Disconnect (circuit breaker)

is open or a battery cabinet fuse is blown. The battery is not available to power the
inverter if needed.

• Retransfer Inhibited (red) - An indication that the inverter is out of

specification or has lost phase lock with the bypass power source. Wh en active in
conjunction with the Transferred to Bypass indicator, power can not be
retransferred from the static bypass switch back to the inverter.

3.4.6 Emergency Power Off Pushbutton

To be used only for emergency conditions whe re instant shutdown of the

UPS is required. The red EPO pushbutton is normally illuminated so th at it may
be located easily, even in the dark. Depressing the EMERGENCY POWER OFF
(EPO) pushbutton results in immediate shutdown of operations, opening all UPS
breakers and the DC (battery) disconnect, the audible alarm sounds and all power
to the critical load is shut off. Once the EPO has been activated, the UPS must be
manually restarted. (The EPO also may be activated remotely by a contact closure.)

CAUTION

Any time the UPS has been shut down by using the EPO,
the system should be carefully checked by trained facilities
personnel before restarting.

3.5 System Controls

Controls for the UPS, with the exception of the pushbuttons located on the

face of the UPS module indicator panel, are situated inside the right-hand door of
the module cabinet. Since the cabinet is routinely kept locked, this provides some
degree of security from tampering with the system.

UPS CONTROL switch: This switch is rotated clockwise to energize the

power supply to turn on the system logic or Digital Signal Processor logic.

INPUT CIRCUIT BREAKER: When closed, allows UPS input power to

supply the rectifier and SBS input on units having a single input.

BYPASS CIRCUIT BREAKER: Used primarily for ma intenance purposes.

When closed, it enables the UPS to be de-energized for ma intenance procedures
while continuing to supply power to the critical load.

STATIC SWITCH BYPASS CIRCUIT BREAKER: (On dual input units

only.) When closed, allows reserve input to supply power to the Static Switch.

OUTPUT SWITCH: When closed, connects the cri tical load to the inverter

and static bypass switch.

3.6 UPS Operating Procedures

It is important for saf ety and the protection and perf ormance of the UPS that

the step-by-step instructions for each procedure be followed in the sequence given.

3.6.1 System Startup Procedure

Before initiating UPS startup, make sure that:

• All circuit breakers/switches are OFF (open).

• The DC (Battery) disconnect switch on the battery pack is OFF (open).
Then --

Each of the following steps must be completed before going to the

next step. Failure to do so may result in interruption of power to the
critical load.

1. Rotate UPS CONTROL switch

knob clockwise to ON to energize the system or
DSP logic. If this screen appears, the UPS is not
in operable condition. Phone Customer Service
at [phone] for assistance.

SECTION IV

Maintenance

4.1 General

Proper maintenance, both preventive and remedial, is the key to optimal
operation of the UPS and will ensure a long and useflil life of the equipment.
Preventive maintenance includes regularly performed procedures designed to
prevent system malfunction and obtain maximum operational efficiency. Re­medial maintenance consists of troubleshooting the system in order to effect
repairs. Troubleshooting the UPS involves following a logical sequence of steps
which will determine the cause of an alarm and/or malfunction within the shortest
time frame safely possible so as to expedite the repair and return of the equipment
to normal service.

The manufacturer recommends that the monitor panel be inspected
visually every eight-hour shift to see that lights are operating and no alarm
conditions exist. The Alarm History should be checked at this time (see
Paragraph 3.6.2) to determine if any recent alarms have gone un-noticed. If
any unusual conditions exist, call facility maintenance p ersonnel or Service
Hotline: [phone] or (outside U.S.) 919-871-1800.

4.2 Safety Precautions

For safe and successful maintenance on the system, certain basic safety
precautions must be observed, necessary tools and test equipment must be
available, and properly trained maintenance personnel must be involved.

The following basic safety practices should always be observed:

1. Always be aware that hazardous voltages a re p resent within the UP S even
when the system is not operating.

WARNING

On a single-input UPS, when input voltage does
not equal output voltage, output transformer
(T2) is energized in Maintenance Bypass Mode.

2. Ensure that UPS operating and maintenance personnel are thoroughl y familiar
with the equipment and with the contents of this manual.

BP+2.9X
11/95

Page 4.1

SECTION IV

Maintenance

4.2 Safety Precautions (continued)

3. Never wear metal jewelry such as rings or wrist watches when workin g on the
UPS equipment.

4. Keep cabinet doors closed and secured during normal operation.

5. Never guess about safety procedures. If any doubt exists, ask someone who
knows.

6. Always be aware of the presence of high voltage within the UPS.

Check with a voltmeter to make sure power is off and conditions are safe before
attempting to make repairs, adjustments, etc. within the unit.

7. Above all, always USE COMMON SENSE!

4.3 Preventive (Periodic) Maintenance

The following paragraphs describe preventive maintenance procedures

which, when followed, will increase the reliability and efficiency of the UPS

system operations.

4.3.1 Air Filters

Filters, installed in the bottom of the cabinet, eliminate particles from the air
which is used to cool the UPS. In time, particle accumulation in the filters will
reduce airflow through the system causing a rise in operating temperatures,
triggering an alarm condition and resulting in shut down of the UPS. Filters should
be checked and cleaned or replaced at least every 30 days in a clean environment,
and no more than 7 days in a dirty environment.

Models of 125 and 150 kVA have two filters; other models have only one.
Loosening a clip beneath the UPS near the front allows the filter to drop down and
you can slide it out. Insert new filter and twist clip to secure it in place.

Filters are standard fiberglass furnace filters of the following sizes:

10-100 kVA UPS - 16" x 25" x 1" 125-150 kVA UPS - 14" x 25" x 1"

BP+2.9X
11/95

Page 4.2

SECTION IV

Maintenance

4.3 Preventive Maintenance (continued)

4.3.2 Cable Connections

Cable connections to circuit breaker and switch terminals should be
checked whenever the system is powered down and at least annually. This
necessitates removal of the circuit breaker panel to gain access.

WARNING

Be aware of the presence of high voltages within the
UPS! When the system is shut down, wait at least
five (5) minutes after all panel lights go out before
proceeding. Then check for the p resence of power
with a voltmeter across the input and output
terminals.

4.4 Remedial Mainte nance (Troubleshooting)

Remember the International Power Machines 24-Hour Hot Line:

Phone: [phone]; (outside U.S.) 214-272-8000

is always available to provide advice and assistance on your UPS.

4.4.1 General

When properly installed, operated and maintained your International P ower
Machines BalancedPower Plus UPS will provide long, reliable power protection
with little need of remedial or corrective maintenance actions. However, this section
contains information as to problem isolation techniques and recommended actions
to be taken so as to effect repairs on the UPS.

BP+2.9X

Page 4.3

SECTION IV

Maintenance

4.4 Remedial Mainte nance (continued)

4.4.1 Gener al (c o nti nu ed )

Because of the modular design o f the BalancedPower Plus UPS, corrective
action in many instances requires replacement of a major assembly or
subassembly. For this reason, troubleshooting information as containe d herein is
generally limited to immediate action that may be taken on site to correct a specific
alarm condition. If such immediate action does not remedy the situation, contact
the 1PM 24-Hour Hotline for assistance.

In general the BalancedPower Plus UPS is designed so that the operator
should not find it necessary to have access to any area of the equipment except the
Digital Monitor Panel and the circuit breake rs, switch and fuses inside the right­hand door.

WARNING

Do not remove front plastic shield,
front panel around the circuit breakers
or either side panel unless
all power to the UPS is OFF. Only
trained maintenance personnel should
remove any of these panels.

4.4.2 Status/Alarm Indicators

The LED status/alarm indicators on the monitor panel are described in
Paragraph 3.4.1. Specific action that may be taken in case of alarm c onditions is
described in Table 3-2, a part of Paragraph 3.6.2.

BP+2.9X

Page 4.4

SECTION IV

Maintenance

4.5 Fuses

There are four (4) fuses adjacent to the UPS CONTROL switch inside the
front door. If one of these fuses is blown, the control logic will not become energized
at startup. Once the UPS is started, it will operate even though one o r more of the
fuses is blown.

In case a fuse blows, replace it with a fuse of the same make and size.

These are the only fuses available to the user unless he or she has had
authorized factory training.

4.6 Battery Maintenance

4.6.1 Safety Precautions

Servicing of batteries should be performed or supervised by personnel
knowledgeable of batteries and the required precautions. Keep unauthorized
personnel away from batteries.

4.6.4 Batt ery Test

Batteries should be tested whenever a batter y-related problem is susp ected
or at annual intervals. The procedure described is for individual batteries and
requires the use of a Balkamp 700-112 Battery Tester or equivalent. The Balkamp
unit is available at most NAPA auto parts stores or from IPM.

The tester is rated for 100 amps, 12 vdc. It checks voltage under load.

Batteries should be tested in their fully-charged state, but not within 24
hours of having been equalized (recharged). Batteries should be left in their trays
during testing.

1. Perform Maintenance Shutdown procedure (Paragraph 4.6.2).

2. Remove two bolts and slide out the desire d battery tray onto a lift hand

truck.

3. Test each battery separately.

4. Using a digital voltmeter which can be read to 0.01 vdc, check the voltage
across the posts of the batteries, one at a time. Record the voltage readings for each
battery. If the voltage does not read at least 12.40 vdc, the battery probably should
be replaced. You may try to recharge the battery, but it probably won't hold a
charge. For replacement procedure see Paragraph 4.6.5.

5. If the battery's voltage is satisfactory, use the battery tester. Attach the red
battery tester cable to the positive (+) battery pole; attach the black cable to the
negative (-) battery pole.

6. Press the LOAD switch. (If using a brand of tester other than the Balkamp,
follow the tester's operating instructions.)

7. In approximately 10 seconds, the tester n eedle should be in the "good"
(green) area. If not, the battery should be replaced.

8. Perform the same tests on all batteries i n the cabinet . (Allow the tester to
cool between tests.)

9. For proper operation, each battery in the cabinet should show voltage
readings within ±0.10 vdc of their average. If full agreement of battery voltages
cannot be obtained, contact Service Hotline [phone].

10. Return the battery trays to their normal position. When each tray is fully
back, replace the two bolts that fasten it to the slide. Reconnect the battery tra y
cables.

Spares, Training Maintenance

5.1 Spare Parts

To facilitate service on the BalancedPower Plus UPS, it is recommended
that a spare parts stock be maintained on site. Investment in a spares stock
ensures immediate parts availability when required, thereby providing for faster
service and greater protection from costly system downtime.

International Power Machines can supply any of several recommended
Spares Levels to meet differing requirements. The desired Mean-Time-To-Repair
and the travel time from IPM's nearest Service Center would normally determine the
approximate level of spares to be stocked.

This section lists typical spare parts for a UPS of the size shown on the cover
page of this manual. It is not applicable to other size UPS.

For further information concerning the stocking of spare parts, or to order
replacement parts, please contact:
