1.0 Introduction
1.1 Overview
The UPS is a high performance standby uninterruptible power source designed to protect
computers and peripheral devices such as monitors, modems, tape drives, etc. from utility
line failures which could result in the loss or corruption of valuable data. In the event of
a utility failure such as a blackout, brownout, or sag, the UPS rapidly transfers loads
(computer equipment) to an alternative power source. This alternative power is derived
from a battery within the UPS and provides the user with ample time to save files and
properly close operations. A chart in section 9.0 shows how much time your equipment
can remain operating during a utility failure before the UPS’s batteries are drained. Under
normal conditions when the utility voltage is within proper limits, the UPS maintains the
battery in a charged condition and serves to isolate your equipment from surges and high
frequency electrical noise.
After following the installation procedures and reading all the safety instructions, your
computer equipment will be protected from hardware damage and loss of data caused by
power problems.
1.2 User replaceable battery
The UPS provides user-safe access to the batteries for quick, easy replacement. The UPS's
Test function (400VA and 600VA models) helps you determine when the battery is weak
and requires replacement. New battery kits can be obtained from your dealer or the
factory — simply call the Customer Service number on the cover of this manual. Your
UPS's old, worn battery can be returned in the new battery kit's packaging for recycling.
1.3 Option switches
Option switches allow you to adjust the UPS for applications where frequent utility voltage
fluctuations cause the UPS to transfer to on-battery operation too often. Audible alarm
functions can be altered so that warning of utility failure or low battery conditions are
given when desired.
Page 2
1.4 Test / Alarm Disable switch
A dual function Test / Alarm Disable switch (400VA and 600VA models) allows you to
check for proper operation by initiating a transfer to on-battery operation. This test
ensures that the UPS is not overloaded and will support the system load during an actual
power disturbance. By using the Test function throughout the life of the UPS, you can
estimate when the UPS's battery should be replaced. During a utility failure, the Alarm
Disable portion of the switch can be pressed to silence the audible alarm.
1.5 Surge suppression and EMI/RFI filtering
The UPS provides high performance surge suppression and EMI/RFI (electromagnetic
and radio frequency interference) filtering. The UPS suppresses surges defined by the IEC
801-5 standard to levels well below that which is compatible with your computer.
1.6 Remote interface
The 600VA model is equipped with a remote computer interface port that is capable of
signalling utility failure and low battery conditions. It also allows for unattended
shutdown of computer operations. When teamed with PowerChute UPS monitoring
software, you may select operation of power event logging, power event notification,
automatic restart upon power restoration, and battery conservation features.

2.0 Safety !
To reduce the risk of electric shock, disconnect the Uninterruptible Power Source from the
mains before installing a computer interface signal cable (when used). Reconnect the
power cord only after all signalling interconnections have been made.
Connect the Uninterruptible Power Source to a two-pole, three-wire grounding mains receptacle. The receptacle must be connected to appropriate branch protection (fuse or circuit breaker). Connection to any other type of receptacle may result in a shock hazard and
may violate local electrical codes.
This Uninterruptible Power Source has an internal energy source (the battery) that cannot
be de-energized by the user. The output may be energized when the unit is not connected
to a mains supply.
To properly de-energize the Uninterruptible Power Source in an emergency, move the I/O
switch to the O (off) position and disconnect the power cord from the mains.
Avoid installing the Uninterruptible Power Source in locations where there is water or excessive humidity.
Do not allow water or any foreign object to get inside the Uninterruptible Power Source.
Do not put objects containing liquid on or near the unit.
To reduce the risk of overheating the Uninterruptible Power Source, avoid exposing the unit
to the direct rays of the sun. Avoid installing the unit near heat emitting appliances such as
a room heater or stove.
The Protective Earth conductor of this UPS carries the Leakage Current from the load devices (computer equipment). This UPS generates approximately 0.75 mA of leakage current. To ensure a safe limit of 3.5 mA, the total leakage current of the load devices should
be limited to 2.75 mA. If you are unsure of the leakage current from the load devices, ensure that this product is plugged into a 3-wire receptacle that has a reliable (low impedance)
Protective Earth connection to provide a safe path for the leakage current, and replace the
powercord to the UPS with one that has a locking type plug (IEC 309) rated a minimum of
10 A. This powercord may require the services of a professional electrician for the installation of the matching wall receptacle.

3.1 Receiving inspection
Once the UPS has been removed from its shipping container, it should be inspected for
damage that may have occurred while in transit. Immediately notify the carrier and place
of purchase if any damage is found. Two output jumper cords are provided with the UPS.
The packing materials are recyclable. Save for reuse or disposed of them properly.
3.2 Placement
The UPS may be installed in any protected environment. The location should provide
adequate air flow around the unit, in an atmosphere free from excessive dust, corrosive
fumes or conductive contaminants. Do not operate the UPS in an environment where the
ambient temperature or humidity is outside the limits given in the Specifications section
of this manual.
3.3 Load types
The UPS is designed to power all modern computer loads and associated peripheral
devices such as monitors, modems, cartridge tape drives, external floppy drives, etc. The
UPS is not rated to power life support equipment (as described on the rear cover of this
Caution: The output waveform of this UPS is a sine wave approximation suitable for use
with modern computer power supplies. Other load types may malfunction. In particular,
Page 8
ferroresonant type regulating transformers are not recommended. Use of a surge
suppressor connected to the output of this UPS may unnecessarily load the UPS when onbattery. This UPS contains high performance surge suppression - additional suppression
components are not required and are not recommended. If in doubt, please consult the
equipment manufacturer or the factory.
3.4 Connecting to the Utility
The UPS is furnished with two 1.8 meter output power cords for connection to computer
equipment having “IEC 320” male appliance couplers at their input. However, due to the
variety of plug connectors required for connection to electrical service in countries where
the UPS may be operated, an input line cord is not supplied from the factory. In most cases
this will not be a problem as the input cord which currently powers your computer
equipment may be swapped with one of the supplied output cords. Hence, the swapped
out line cord can be used instead as the input line cord for the UPS. If this is not the case,
ask your local dealer or the factory about obtaining an input line cord for your application.
Extra output power cords are also available from the factory.
The UPS is compatible with all 220, 230 and 240 Vac mains voltages. During a mains
failure, the UPS powers your load at a nominal voltage of 225 Vac.
3.5 Battery charging
The UPS is shipped from the factory with its internal battery in a fully charged state.
However, the battery may lose some charge during shipping and storage. The battery
Page 9
should be recharged before conducting the following Test for proper operation (section
3.7) and to ensure that the UPS will provide expected run time. The UPS may be used
immediately upon receipt, but may not provide expected run time in the event of a utility
failure. The battery will recharge to full capacity within 6 hours when the UPS is plugged
in and switched on. Once the battery has obtained a full charge, the UPS will maintain the
charge as long as the UPS is plugged in, regardless of the position of the power I/0 switch.
3.6 Connecting Your Equipment to the UPS
To ensure that your computer equipment will be protected during a utility failure and that
you receive expected run time, it is important that you determine the total power needs
of the equipment you wish to protect with the UPS. The power requirements of your
equipment should be less than or equal to the capacity of the UPS. The capacity rating of
the UPS, in both Volt-Amperes (VA) and Watts (W), is given in the Specifications section
of this manual.
The power demands of your equipment can be read from the Run Time Verses Load
(section 9.0) chart or may be deduced from the equipment name plates. The Run Time
Versus Load chart gives equipment power requirements (load) in VA for computer
systems common in the office environment today. If your equipment is not listed in the
chart, the following instructions will help you to determine their power needs.
3.6.1 Computer equipment manufacturers must provide a load rating for their products.
Usually, the rating is written on a name plate or label near the line cord. The rating may
be given in units of Amps (A or Amax), Volt-Amperes (VA) or Watts (W). Jot down the
load rating of all the equipment you wish to protect.
3.6.2 All noted load ratings should be converted to Volt-Amperes (VA) so that all
equipment power requirements can be added using the same units of measure.
3.6.3 If load ratings are given in Watts (W), convert to an estimate of power requirements
in VA by multiplying the value in Watts by 1.4.
3.6.4 If load ratings are given in Amps (A or Amax), convert to an estimate of power
requirements in VA by multiplying the value in Amps by 230. Unfortunately, many
computer manufacturers overrate the power requirements of their equipment in order to
be conservative and to cover the extra power demand of user added expansion boards. If
the VA requirement that you have computed seems high or is already greater than the
Page 10
capacity of the UPS, don’t worry. The next section describes a test that you can perform
to determine whether or not your equipment and the UPS are compatible, even if the
computed power requirement of your equipment is 50% greater than the capacity of the
3.6.5 Once all power requirement figures have been converted to VA units and added
together, simply determine whether the power requirements of your equipment is less
than or equal to the capacity of the UPS. If this is not the case, then it must be decided which
equipment should be left unprotected by the UPS. See section 3.8 covering overloads.
3.6.6 An example of how to determine the power requirements of a computer system is
given below.
Example - labels found at system equipment rear panels
230 V~ .2A
230 V~ 1A
230 VAC, 70W
The power requirements of the example computer, monitor and external tape drive may
be calculated as follows:
Computer VA
Monitor VA
Tape Drive VA
230 x 1 A
70 x 1.4
230 x .2A
= 230 VA
= 98 VA
= 46 VA
= 374 VA
In this example, a UPS with at least 374 VA capacity can be employed to protect the
computer, monitor and external tape drive. However, a UPS with somewhat lower
capacity may still be used if the following test for proper operation is successful.
3.6.7 Once you have determined that your equipment and the UPS are compatible, plug
your equipment into the UPS’s rear panel output receptacles.
Page 11
Note: Do not plug laser printers into this UPS! The power requirements of a typical laser printer are much larger than the requirements
of other computer peripherals and may trip the UPS’s rear panel
circuit breaker. Plug laser printers into a quality surge suppressor.
Remember that print jobs can be re-queued when the power is
3.7 Test for Proper Operation
After the UPS has had a chance to recharge its battery, turn on the UPS’s power I/0 control
and switch on your computer equipment. The indicator within the switch should be
illuminated and your equipment should operate normally.
To test the operation of the UPS, simply unplug its input cord or press and hold the Test
switch (on units so equipped) to simulate a utility blackout. The lamp within the power
I/0 switch will flash and UPS will immediately transfer your equipment to power derived
from the UPS’s internal battery. During this time, the UPS will emit one beep once every
5 seconds to remind you that your equipment is operating from a source of power that is
limited in duration. Restore normal operation by releasing the Test control or by plugging
in the line cord. Observe that your equipment operates normally during both transfer
from utility power to UPS power and back again. Repeat this test four or five times to
ensure proper operation. See the following section covering Overloads if abnormal
operation is encountered. The power I/0 control switches power to your equipment. If
you leave your equipment power switches on, the I/0 power control can be used as a master
on/off switch!
3.8 Overloads
If the total power requirement of your equipment is much greater
than the capacity of the UPS, the UPS’s rear panel circuit breaker
may trip. This is called an overload situation. Once the circuit
breaker trips, the UPS will attempt to operate the load using its
internal power source. This may result in an unexpectedly short
run time or, if the overload is severe, the UPS will immediately shut
down and cease to power the load. In this case, the UPS will emit
a loud tone to alert you of the overload. If this occurs during your
test, turn off the UPS and decide which equipment will be left
unprotected by the UPS. The circuit breaker may be reset (press
button) when the overload is removed.
Page 12
4.0 Principles of Operation
Below is a block diagram showing the major components of your UPS. These blocks are
described on the following pages, and are labelled accordingly.
Block diagram showing all major components of your UPS.
Page 13
4.1 Noise and surge suppression
The UPS contains high performance EMI/RFI (Electro-Magnetic and Radio Frequency
Interference) noise and surge suppression circuitry to protect your computer equipment.
The UPS provides this suppression continuously, whether or not it is turned on. Normally, the UPS will continuously filter surges and electrical noise without using the battery
charge. The suppression circuitry will reduce the amplitude of these power disturbances
to conform to the strict requirements of all modern computing equipment.
The illustration above shows what a typical “medium” amplitude surge or spike looks like
when present on the utility voltage. Surges up to 15 times larger than this are easily
suppressed by the UPS. Surges are commonly caused by nearby lightning activity and
motor load switching created in air conditioners, elevators and heat pumps.
The illustration above shows what EMI/RFI noise looks like when present on the utility
voltage. The UPS “filters” out this noise with components whose electrical resistance is
very high at radio frequencies. EMI/RFI noise is commonly created by the same activity
which produces surges but can also be caused by nearby radio transmitters and blinking
neon bulbs and signs.
Page 14
4.2 Load transfer switch
The load transfer switch is actually an electro-dynamic relay which serves to rapidly
transfer your computer equipment (load) from the utility to the UPS’s alternate power
source in the event of a utility failure. When the utility is restored to within safe limits, the
switch acts to re-transfer the load to the utility. The time required for the relay to transfer
your load to either power source is much, much faster than that which is required by any
modern computer or computer peripheral device.
4.3 Battery Charger
The UPS's battery charger converts the alternating current (AC) supplied by the utility to
a direct current (DC) which is compatible with the battery. The charger maintains the
battery at a constant voltage to ensure that the battery will have the capacity to support
your load as often as possible. This charging method, known as “float” charging, provides
maximum battery service life and minimal internal heating. The battery is charged
whenever the UPS is plugged in, whether or not it is switched on.
4.4 Battery
The UPS’s battery is an energy source much like the battery in an automobile. Also, like
most automobile batteries, the UPS’s battery is a modern maintenance free lead-acid type;
it is sealed and leakproof. The battery has a typical service life of 3 to 6 years. The service
life is extended when the UPS is kept in a cool environment, below 30°C or 86°F.
4.5 Inverter
The UPS must convert the battery’s energy into a form that your computer equipment can
rely upon during a utility failure. This is the job of the UPS’s inverter. The UPS converts
the battery’s DC to AC using solid state devices (transistors), controlled using a technique
known technically as “pulse width modulation”. This technique is highly efficient which
means that little battery power is wasted in the conversion process. Hence, your
equipment can run for long periods from the UPS before the battery’s capacity is spent.
Page 15
4.6 Transformer
The UPS’s transformer is an electrical component which “steps up” the output voltage of
the inverter to the normal utility line voltage. In addition, it serves to isolate the UPS from
equipment failures.
4.7 Monitoring and control electronics
This block is the “brain” of the UPS. The monitoring and control circuitry detects utility
failures such as blackouts, sags and brownouts; synchronizes the inverter’s output
frequency and phase to that of the utility; detects low battery voltage conditions; directs
the load transfer switch; and governs all user controls, indicators and computer interface
4.8 Operation during a utility failure
In anticipation of a utility failure such as a blackout, sag or brownout, the UPS continuously monitors the utility voltage and readies the inverter for “synchronous” transfer.
This means the inverter’s phase and frequency is adjusted to match the phase and
frequency of the utility. If the utility voltage falls outside acceptable limits, the UPS rapidly
transfers your equipment to power derived from the UPS’s battery via the inverter and
transformer described earlier. This transfer typically takes place within 8 milliseconds.
Once operating in this mode, the UPS will beep once every 5 seconds to alert the user that
there is limited time available to save files and shut down the computer. If the utility power
is not restored to normal, the UPS will eventually sound continuous beeps to alert you that
less than two minutes remain before the UPS shuts down and ceases to power your
equipment. This is called a low battery condition which means that the UPS’s usable
battery capacity is nearly spent. The UPS will automatically shut down if the UPS is not
turned off during the low battery alarm.
If the UPS detects the return of normal utility voltages at any time during operation using
its alternate power source, the inverter voltage will be smoothly re-synchronized to match
the phase and frequency of the utility. Once synchronized, the load transfer switch will retransfer your equipment to power supplied by the utility. After an extended utility outage,
the battery charger resupplies the battery with energy at a pace which is consistent with
maximizing the service life of the battery (the battery could be charged faster, but wouldn’t
last as long).
Page 16
Utility voltage sags are temporary amplitude reductions of the normal line voltage level.
Utility voltage sags can be caused by local high power demand equipment such as
elevators, air conditioners, shop tools and electric heaters. Brownouts, defined as long
lasting utility voltage reductions, are sometimes initiated by the power company itself.
During the hot season, the utility may choose to reduce the line voltage in order to cope
with the huge power requirements of home and commercial use air conditioners.
Blackouts are defined by a complete loss of power. Often, blackouts are caused by
accidents or acts of nature. However, they can also be created by overloaded “branch”
circuits (building wiring segregated by fuses or circuit breakers), faulty circuit breakers or
even a tripped-over line cord!
Page 17
5.0 Controls and indicators
5.1 Power I/0 switch
The power I/0 switch controls power to the UPS and its output
receptacles. When the switch is on, the UPS operates and your
computer equipment will be powered. When the switch is off, the
UPS is de-energized and your equipment is unpowered. If your
equipment switches are left on, the entire system can be operated
by using just the power I/0 switch! The lamp within the power I/0
switch illuminates whenever normal voltages are present at the
output receptacles. When the switch is in the on position and the
lamp is extinguished, the UPS has shut down due to overload or low battery.
5.2 Test/Alarm Disable switch (on units so equipped)
When operating during a utility power outage, the UPS will emit a beep once every five
seconds. This beep can be silenced by pressing the Alarm Disable control (bottom of
toggle switch.) However, the UPS's low battery warning will still
sound in the event of an extended utility outage.
When the Test portion of the Test/Alarm Disable switch is pressed,
(top of toggle switch) the UPS simulates a power outage and
transfers your load to the alternate power source. This feature
allows you to determine that computer equipment protected by
the UPS operates normally during transfers. It also provides a
convenient means of testing the UPS’s battery. If the Test control is held depressed, the
UPS will operate your equipment from power derived from the battery continuously. If
during the test the low battery warning is sounded prematurely and the load is known to
be normal, then the battery is weak and requires extended recharge or replacement (see
section 7.0).
5.3 Audible alarm
During a utility failure, the UPS emits a beep once every five seconds to warn you that your
equipment is operating from a source of power which is limited in duration. The alarm
can be defeated using the Alarm Disable switch (on units so equipped) or, in advance of
the outage, via option switch #1. In the event of an extended utility failure, the UPS will
Page 18
sound a loud tone 2 minutes in advance of shut down due to battery capacity exhaustion.
Once shut down, the UPS will return to the periodic beep. The UPS should be turned off
at this point to cease the alarm. In the event the UPS encounters a severe overload, the UPS
will shut down and emit a loud tone. The alarm is reset when the UPS is turned off.
5.4 Option Switches
The option switches are located on the rear panel and are set
to the down (off) position as supplied from the factory.
5.4.1 Option Switch #1
When option switch #1 is set to the up (on) position in advance of a utility failure, the
UPS’s audible utility failure alarm is defeated. When the switch is set to the down position
(this is the factory setting), the UPS beeps once every five seconds when the utility voltage
has fallen outside acceptable limits. Regardless of the position of this control, the UPS will
still sound a loud tone during the low battery conditions. This feature is convenient where
brief power interruptions are common and the audible alarm becomes an annoyance.
5.4.2 Option Switch #2 and #3
Option switches #2 and #3 adjust the utility voltage at which the UPS will transfer your
computer equipment to the UPS’s alternate power source. Adjustment of the “transfer
voltage” is desirable where frequent line voltage excursions or line voltage distortion
cause the UPS to transfer many times a day. The switches may be set according to the
following charts if it is known that your equipment will operate normally under such line
voltage conditions. Normally, the switches should be left in the down position (this is the
factory setting).

5.4.3 Option Switch #4
Option switch #4 sets the internal operating frequency of the inverter. It should be set to
match the local line frequency. When in the down (off) position, the UPS will operate
properly with a 50 Hz line. If your local line frequency is 60 Hz, set the option switch #4
in the up (On) position.

6.0 UPS monitoring
6.1 Overview
A UPS system alone provides excellent protection from brief power problems. However,
during an extended power outage an unattended computer system will eventually shut
down due to battery capacity exhaustion. To prevent data corruption when the UPS shuts
down, the computer must be informed by the UPS of impending shut down and take
appropriate file-saving measures. This important function is called “UPS monitoring.”
The UPS’s computer interface port is the means by which your UPS communicates with
a computer system.
Some computer operating systems have built-in UPS monitoring. These systems require
various hardware interfaces. Interface kits for all operating systems that support UPS
monitoring are available from your dealer. In addition, your dealer also offers PowerChute software which enhances such built-in UPS monitoring. Versions of PowerChute
are available which add the UPS monitoring function to the many operating systems
which do not inherently provide UPS monitoring.
6.2 PowerChute Software (600 VA only)
PowerChute software provides complete data protection for most operating systems. This
software is a background process that monitors the UPS through a RS-232 serial port on
the host. PowerChute offers user notification of impending shutdown, power event
logging, auto-restart upon power return and UPS battery conservation
features.PowerChute is available for many platforms including Novell, LAN Manager,
AppleShare, most UNIX-based operating systems, and DEC VAX/VMS. Please visit
APC's Web site at http://www.apcc.com for further information.
Caution: Use only factory supplied or authorized UPS monitoring cables!

7.2 Replacing the Battery
You can expect to receive 3 to 6 years of service life from the UPS's battery when installed
in a cool, dry location. If you suspect the battery is weak, allow the UPS to charge the
battery for at least 6 hours and perform the Test for proper operation described in section
3.7. If after repeating the test you find that the run time is still too short, follow the
procedures below to replace the battery.
Note: Please read the cautions at the beginning of this section.
7.2.1 Turn off the UPS and unplug it from service. Lay the UPS on its left side and remove
the two battery door screws. Remove only the screws indicated on the battery door.
7.2.2 Gently pull out the battery by grasping the white tab.
7.2.3 Remove the two wires connecting the battery to the UPS. To loosen the wire
connectors, gently wiggle the connectors side-to-side while pulling straight back from the
mating battery connector.
7.2.4 Connect the battery wires to the new battery. The red wire is positive (+), the black
wire is negative (-).
7.2.5 Position the new battery as shown below and place it into the UPS. Arrange the wires
so that they will not interfere with the battery installation.
7.2.6 Close the battery door and fasten the two battery door screws.
7.2.7 Return the worn battery to the factory for recycling.

7.3 Obtaining Service
The troubleshooting chart in section 7.1 covers most of the difficulties that a user may
encounter under conditions other than a failure of the UPS itself. For problems not
covered in the chart, follow the below listed instructions.
See the troubleshooting chart and eliminate the obvious. A tripped UPS circuit breaker is
the most common problem encountered and is user resettable once excessive loads are unplugged from the UPS.
If the circuit breaker is OK, note your UPS model, serial number and date of purchase.
Contact the Customer Service Department at the phone number given on the cover of this
Be prepared to provide a description of the problem. A technician will help you solve the
problem over the phone if possible, or will give you a Return Material Authorization Number (RMA#).
If the UPS is within the warranty period, repairs will be performed free of charge. If it is
not within the warranty period, there will be a charge for repair.
Pack the UPS in its original packaging. If you no longer have the original shipping materials, ask the technician about obtaining a new set. It is very important that you pack the
UPS properly to avoid damage in transit. Never use styrofoam beads for packing because
the UPS will settle through beads and become damaged. Damages sustained in transit are
not covered under warranty. Enclose a letter in the package with your name, RMA#, address, copy of sales receipt, description of trouble, phone number and check (if necessary).
Mark your RMA# on the outside of the package. The factory cannot accept any package
without this marking.
Return your UPS via insured, prepaid carrier to the address on the rear of this booklet.

8.0 Storing the UPS
8.1 Storage Conditions
The UPS should be covered and stored in an upright position, in a cool, dry location. The
UPS should be stored with the battery in a fully charged state. This means that the UPS
should be allowed to charge the battery for at least 6 hours before the UPS is switched off
for storage.
8.2 Extended Storage
To achieve expected run time following extended storage, the UPS should be allowed to
refresh the battery for 12 hours once every 6 months in environments where the ambient
temperature is -15°C to +30°C (5°F to 86°F). For extended storage in environments where
the ambient temperature is +30°C to +45°C (86°F to 113°F), the UPS should be allowed
to refresh the battery for 12 hours once every month.
