1. Introduction

Overview

This SwitchUPS is a high performance standby uninterruptible power system
(UPS) designed to provide clean, reliable AC power to computer loads and
electronic devices. When utility failure, low or high voltage intermittently, UPS
can feed your computer or electronic appliances without any interruption. It
can keep you away from brownouts, spikes, lightning and high frequency
interference. It can automatically save your computer data, protect your
software, even the hardware, to ensure your computers or precision equipment
work functionally and efficiently.

1.1 Operation principle

1.1.1 Utility normal: The UPS offers the pure and stable AC output power by
the synchronous voltage regulator and EMI/RFI filter. A unique mode of
operation, named AutoBoost, serves to regulate the load voltage by
compensating for brownouts or sags, and AutoTrim allows continuous
on-line operation during over line voltage conditions. This is
accomplished without the need to draw power from the UPS’s battery.
In anticipation of utility failure, the UPS continuously monitors the line
and prepares the inverter frequency for synchronous transfer of the
load.

1.1.2 Utility failure or abnormal: Upon occurrence of utility voltage failure
such as a blackout, severe brownout or an over-voltage condition, the
UPS transfers the load to power derived from battery. Transfer to the
“On-battery” mode of operation takes place typically within 2
milliseconds. The inverter’s output voltage wave shape is a low
distortion sine wave. Resynchronization and retransfer to on-line
operation is automatic upon recovery of the line voltage to within
normal limits.

1.2 Products features

1.2.1 AutoBoost/AutoTrim
AutoBoost/AutoTrim allows continuous on-line operation during
extended brownouts or low/high line voltage conditions. The UPS
compensates for the reduced/increased line voltage by
boosting/trimming the load voltage to a value 10% above the input.
Reliability is enhanced because the limited battery capacity is saved for
complete utility failures.

1.3.2 Battery replacement indicators and test

The UPS provides both visual and audible Replace Battery indications.
The Indications are based on the result of an actual load test on the
battery. By exercising the UPS’s battery during a startup test, the UPS
is able to detect a weak battery before it is put into service. In
applications where the UPS is not turned off daily, or where the UPS is
purposely left operating unattended, the UPS automatically conducts this
self test.

Page5

1. Introduction

1.3.3 Remote interfaces
The UPS provides a remote computer interface capable of full bi­directional RS-232 communications. When combined with UPS
monitoring software and a serially connected local PC, power quality
related events can be logged. UPSilon2000 offers all the features of
UPS monitoring and management software, plus the ability to control
orderly and unattended network or multi-user computer system
shutdown during an extended power outage. Also available for the UPS
is the SNMP (Simple Network Management Protocol) Adapter to provide
load type independent remote monitoring and management across
Ethernet or Token Ring based LANs or WANs capable of routing IP
messages. Using any standard Network Management System (NMS)
and the SNMP Adapter, the UPS becomes manageable through a single
familiar interface-from across your building to across the world.
UPSilon2000 software provides complete data protection for most
operating systems such Windows, Linux, Unix, Win NT, LAN manager.
This software is a background process that monitors the UPS through a
RS-232 serial port on the host.

1.3.4 Input and output frequency
The UPS allows any of input frequency, 50Hz or 60Hz. Via the UPS’s
microprocessor, the input frequency can be internally selected. Also
the UPS provides the pure and stable output frequency.

Page6

2. Safety

2.1 Connect the UPS 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.

2.2 To reduce the risk of electric shock, disconnect the UPS from the mains
before installing computer interface signal cable (when used). Reconnect
the power cord only after all signaling interconnections have been made.

2.3 Do not open the UPS cabinet without the instruction from the local service
center, or UPS will not be valid for warranty.

2.4 This UPS has an internal energy source (the battery) that cannot be de­energized by the user. The output may be energized when the unit is not
connected to a mains supply.

2.5 To properly de-energize the UPS in an emergency, move the rear panel I/O
switch to O (off) position and disconnect the power cord from the mains.

2.6 Avoid installing the UPS in locations where there is water or excessive
humidity.

2.7 Do not allow water or any foreign object to get inside the UPS. Do not put
objects containing liquid on or near the unit.

2.8 To reduce the risk of overheating the UPS, 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.

5.1.1 Enable/Switch on the UPS
The Enable/On switch is used to control activation of the UPS and to energize the load
when Option switch 5 is set to the ON (I) position (See section 5.6). When shipped, this
switch is in the “OFF” position to prevent accidental activation of the UPS. The
batteries will not appreciably discharge if this switch is left “ON”(See section

3.2/3.4/3.5).

Note: The UPS may be configured to operate on Auto starting mode (Option switch 5 is

set to the ON (I) position. See section 5.6.

Once powered, all indicators will blink, and the UPS will initiate a battery test.

During the test, the UPS will operate the load from power derived from the
battery. This test function ensures that the UPS is working properly and that
its battery does not require replacement. The test will take about 15 seconds,
and the test is completed when the On Line indicator illuminate. After battery
test, the UPS’s battery charger will be started if required.

In the event the batteries are too weak to support the load during the test,
trouble indicator will be illuminated, and the UPS emits continuous beeps. The
UPS’s battery charger will operate when the utility voltage is over 154Vac

Page14

5. Operation

while trouble indicator is illuminated. Th e on-line indicat or will be illuminated
when the batteries is charged as sufficient as to activate control of the UPS.
The trouble warning cannot be muted.

If you need to do battery test where mains are not available, set Option switch
4 to the ON (I) position. See section 5.6.

Note: If the red Load indicator is illuminated, the UPS is overloaded. Unplug

equipment that does not require backing up, such as a printer, and restart the UPS.

Allow the UPS to charge its battery for at least 8 hours before use. The UPS

recharges its battery whenever the utility voltage is normal and UPS Enable/On
switch is ON. While the UPS was shipped from the factory with the batteries in a
fully charged state, the batteries may lose some charge during shipping and storage.
You may use the UPS immediately without charging, but the Low Battery indicator
may illuminate and the UPS may have reduced backup time until the battery has had
an opportunity to charge.

Note: When moved the switch to the OFF (O) position, this control will de-energize the

UPS and all protected loads.

TEST

will initiate a battery test when Option switch 5 is set to the ON (I) position. This will
force the UPS to operate on-battery for a brief time during which the UPS determines
the strength of the battery. In the event the batteries are too weak to support the load
during the test, the UPS will immediately return to on-line operation.

When Option switch 4 is set to the ON (I) position, pressing the button will switch on
the UPS when the mains are not available.
Once the UPS conn ected to the mains and Op tion switches 4 and 5 are set to the OFF
(O) position, pressing the button will switch on the UPS.

5.1.2 On/Test pushbutton: Once the UPS is energized, pressing the button

Page15

5. Operation

5.1.3 AutoBoost: Illumination of AutoBoost indicator means that the AutoBoost

circuitry has been engaged to compensate for unacceptably low line voltage. The UPS
is capable of operating in this mode continuously without draining charge from the
battery.

5.1.4 On Line indicator: Illumination of the On Line indicator means that the load is

being supplied conditioned power derived from the utility service. The indicator outs
during the blackout, low voltage or over voltage conditions.

5.1.5 AutoTrim: Illumination of AutoTrim indicator means that the AutoTrim

circuitry has been engaged to compensate for unacceptably over line voltage.

5.1.6 Battery capacity bar graph: The battery capacity bar graph continuously displays
the state of battery charge. Where power quality is fair, the UPS will be able to
maintain the battery at 100% of rated capacity. In the event of an extended utility
failure, the capacity shown will decrease at a rate dependent on the load drawn from
the UPS. Large computer loads will cause the battery capacity indication to fall at a
faster rate.

5.1.7 Low battery indicator: When low battery conditions are reached, the bottom-

most bar will illuminate.

5.1.8 Trouble indicator: In the event of an short-circuit of output cable, weak
battery, over/low output voltage or miscellaneous trouble of UPS, the trouble indicator
will illuminate and emits constant tone.

5.1.9 Alarm disable pushbutton: This button may be pressed to silence the

trouble audible warning which of caused by utility failure only.

5.1.10 On battery indicator: Illumination of the On Battery indicator means that
load has been transferred to power derived from the UPS’s battery and that utility
voltage is not within normal limits.

Page16

5. Operation

TEST

5.1.11 Test pushbutton: Once the UPS is energized, pressing the button will
initiate a battery test. This will force the UPS to operate on-battery for a brief time
during which the UPS determines the strength of the battery. In the event the
batteries are too weak to support the load during the test, the UPS will immediately
return to on-line operation.

5.1.12 Replace Battery indicator: Illumination of the Replace Battery indicator and
emits “chirps” occasionally means that the automatic battery test has found that the
battery is weak and requires replacement. The indicator is extinguished following a
successful battery test.

5.1.13 Output power & line voltage bar graph: The output power bar graph displays the
power drawn from the UPS as a percentage of the UPS’s full rated capacity.

5.1.14 Over load indicator: If the UPS becomes overloaded, the overload

indicator will illuminate and the UPS will sound an alarm.

5.2 Battery capacity bar graph

The battery capacity bar graph continuously displays the state of battery charge. In
the above example, the display shows that 75% of rated battery capacity is available.
Where power quality is fair, the UPS will be able to maintain the battery at 100%of
rated capacity. In the event of an extended utility failure, the capacity shown will
decrease at a rate dependent on the load drawn from the UPS. Large computer loads
will cause the battery capacity indication to fall at a faster rate. When low battery
conditions are reached, the bottom-most bar will illuminate, and the UPS emits a short
beeps every 1 seconds.

5.3 Output power bar graph

The output power bar graph displays the power drawn from the UPS as a percentage of
the UPS’s full rated capacity. This example shows that the load equipment is drawing
between 75% and 100% of the rated capacity. When the UPS is loa ded such that four
bar illuminated, thoroughly test your complete system to be sure the UPS will not
become overloaded. A thorough test includes running backup tape drives, disk drives,
etc. If the UPS becomes overloaded, the overload bar will illuminate and the UPS will
sound an alarm.

5.4 Line voltage bar graph

The line voltage bar graph displays the UPS’s input voltage in discrete steps. Line
voltage is disp layed when the On/Test and Alarm disa ble pushbutton are pressed and
held. The example above shows that the UPS’s input line voltage is between 210 and
229 Vac. If no bars are illuminated, an d the UPS is plugged into a known work ing wall
outlet, the line voltage is extremely low. Low input voltage could be a result of an
overloaded branch circuit, a misadjusted service pole transformer or intentional local
service brownout. The UPS will compensate for this problem by boosting the load
voltage supplied to your computer equipment. If all four bars are illuminated, the line
voltage is high and should be checked by a qualified electrician. The UPS will
compensate for this problem by trimming the load voltage supplied to your computer
equipment.

5.7 Extended capabilities

The following sections briefly describe the UPS’s extended capabilities. These
advanced functions are accessed by a computer running optional UPSilon2000 UPS
monitoring software. See the UPS monitoring software literature for more information
on the application of these functions.

5.7.1 Status reporting

● Operating status – When queried, the UPS reports its current operating status.
Reported modes includes on-line, on-battery, Auto Boost, Auto Trim, overloaded output,
low battery, shut down and internal fault.

● Test results – When queried, the UPS reports the stored results of the last automatic
or manually initiated battery test. The user may also test the operation of the UPS’s
visual and audible indicator.

Page21

5. Operation

5.7.2 Monitoring

● Battery capacity – When on-battery, the UPS continuously monitors the remaining
battery capacity as a percentage of the fully charged condition.

● Line voltage and frequency – The UPS continuously monitors the rms line voltage
and the line frequency. Transients lasting less than 0.5 seconds are not reported.
This information can be logged using UPS monitoring software.

● Minimum and maximum line voltage – The minimum and maximum line voltage is
recorded to provide a snapshot of power quality over a user specified interval.
Transients lasting less than 0.5 seconds are not recorded.

● Output power – The UPS continuously monitors the power consumed by the load.
The value given is a percentage of the full load rating of the UPS. This information can
be logged using UPS monitoring software.

● Output voltage, internal temperature, battery voltage, battery capacity – The UPS
continuously monitors the rms output voltage, internal temperature in degrees Celsius,
battery voltage, and the remaining battery capacity as a percentage of the fully charged
condition. This information is valuable for troubleshooting purposes.

5.7.3 Power management

● Shut down – While operating on-battery, the UPS may be directed to shut down
following a user set delay. Controlled shut down of the UPS conserves battery
capacity and exten ds battery l ife because th e UPS is not all owed to run until all battery
capacity is exhausted.

● Shut down with delayed restart – The UPS may be directed to shut down in any
mode following a user set delay, then restart after another user set delay.

● Turn off – The UPS may be directed to turn off immediately or following a user
settable delay.

6. 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 UPSilon2000 software which enhances such built-in UPS monitoring.

6.2 Interface Kits

A series of interface kits is available for operating systems that provide UPS monitoring.
Each interface kit includes the special interface cable required to convert status signals
from the UPS into signals which individual operating systems recognize. Each kit
includes all necessary installation instructions.

6.3 UPSilon2000

UPSilon2000 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. UPSilon2000 offers user notification of impen ding shut down, power
event logging, auto-restart upon power return and UPS battery conservation features.
For selected operating systems, UPSilon2000 offers sophisticated power diagnostic and
network power management features. These include interactive battery testing;
scheduled server shut downs, re-boots and battery testing; detailed power quality
logging and a remote, real time, graphical power status display showing UPS loading
and battery conditions.

8.2 Battery replacement check

You can expect to receive 2 to 4 years of service life from the UPS’s batteries when
installed in a cool, dry location. Battery life is shortened when operated in an
environment where the ambient temperature is normally above 30℃ (86℉).

Page29

8. Difficulty

The UPS automatically performs a battery test upon start up. Th is test actually loads
the battery for a brief time and will detect a weak battery before it is put into service
during a power failure. If the battery is too weak to support the load during this test,
the UPS will illuminate the Trouble indicator and emits continuous beeps. Even in this
case the UPS’s battery charger will operate if utility voltage is over 154Vac if trou ble
indicator is illuminated.

Note: The minimum charging voltage is –20% of nominal input voltage.

The UPS will illuminate the Replace Battery indicator when it is detected that the
batteries can no longer sustain sufficient charge. This means that the UPS would b e
unable to provide power for longer than half the normal interval during an extended
utility failure.
If the UPS illuminates the Replace Battery indicator, perform the following procedures
to be sure that the batteries need replacing.

8.2.1 Use the UPS’s Line voltage bar graph to check that the utility voltage is within a
normal range. The UPS will charge the batteries at a slower rate when operated from
very low input voltage.

8.2.2 Allow the UPS to charge the batteries for at least 8 hours following an extended
utility failure.

8.2.3 Recheck the UPS’s batteries by conducting a battery test. Press the On/Test
pushbutton to initiate the battery test.

8.2.4 If the Replace Battery indicator does not illuminate following the battery test, the
batteries do not require replacement. Extended storage without recharge, or
successive power outages can causes false indications.

8.2.5 If the Replace Battery is illuminated following the battery test, the batteries are
worn and need to be replaced.

8.2.6 Call the Customer Service phone number given on the cover of this manual to
obtain information about battery replacement service or battery replacement kits.

Note: Please see the battery cautions at the beginning of this section.

8.3 Obtaining Service

The troubleshooting chart in section 8.1 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, the procedures outlined below should be followed.

If your UPS should require service:

◆ See the troubleshooting chart and eliminate the obvious.

◆ Note your UPS models, serial number and date of purchase. Contact the Customer
Service Department or local distributor at the phone number given on the cover of this
booklet.

◆ 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 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
packaging the UPS because it 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.

9. Storing the UPS

9.1 Storage conditions

The UPS should be covered and stored upright in a cool dry location. The UPS
should be stored with its battery in a fully charged state. That is, the indicated
battery capacity should be 100% before the UPS is switched off for storage.
Disconnect accessories or cables connected at the computer interface port as such
devices may unnecessarily drain battery charge.

9.2 Extended storage

To achieve expected run time following extended storage, the UPS should be
allowed to refresh its batteries every 6 months in environments where the ambient
temperature is –15℃ to +30℃. For extended storage in environments where the
ambient temperature is +30℃ to +45℃, the UPS should be allowed to refresh its
batteries every 3 months.
