Introduction

Thank you for purchasing Omron's Uninterruptible Power Supply (UPS).

• The UPS protects computers and other devices from surge voltage (a phenomenon in which extraordinary high voltage occurs instantaneously) caused by power failures, voltage variations, instantaneous voltage drops and power failures, and thunders.

• Under usual service conditions, the UPS converts commercial power into a direct current, and reconverted from the direct current to the 100-VAC output of stable sine wave. When detecting a failure of commercial power, the UPS switches itself to the uninterruptible power supply mode, and feed the output of a sine wave through devices linked to the UPS. The UPS is especially useful where power supply conditions are bad (for example, large voltage variations).

• Output capacities are 1KVA/700W for BU100XR2 and 2KVA/1.4KW for BU200XR2.

• The UPS provides the function of the Network Line Surge Protection to protect communications apparatus such as modems from surge voltage that comes through the line (a phenomenon in which extraordinary high voltage occurs instantaneously).

Notes on the use of the Backup UPS

• The UPS is designed and manufactured for OA equipment such as personal computers. Do not use the UPS with the devices that require very high reliability and safety as listed below.

◊ Medical devices that may cause death directly ◊ Particular applications of devices that may cause injury (applications that directly affect the operation

and control of planes, ships, railroads, elevators, and others)

◊ Applications that are always subjected to vibration such as cars and ships ◊ Applications in which a failure of the UPS may cause critical damage or effect on public safety (major

computer systems, main communications equipment, public transportation systems, and others)

◊ Devices with the similar level of importance

• For the devices that adversely affect the safety of people and maintenance of utilities in the event of failure, special considerations related to operation, maintenance, and management of the system must be taken such as a standby system for emergency use and an auxiliary power generator.

• Observe the do's and don'ts of this instruction manual related to the operating and environmental conditions.

• When you want to add the UPS to the critical system that requires very high reliability, contact us; ______.

• Do not modify/alter your UPS.

• The UPS is tailored to a domestic use only. Do not use the product abroad (outside Japan). ◊ Voltages and frequencies may differ abroad and may cause a failure and/or fire.

● Doing so may lead to an abnormal overheat or fire.

Do not wet or spill water on the UPS

● Doing so may cause an electric shock or fire.

Do not insert a metal thing into the Power Supply Output receptacle of the UPS.

● Doing so may cause an electric shock.

Do not insert metal things into the battery connector or add-on battery connector.

● Doing so may cause an electric shock.

Cautions (maintenance)

Before maintaining devices connected to the UPS, turn off the UPS and remove the AC Input Plug from a wall outlet (commercial power).

● Even if you remove the AC Input Plug during the operation of the UPS, the backup function of

the UPS keeps feeding power through the power supply output receptacle of the UPS.

● In a case where the scheduled operation is ON and the AC Input Plug of the UPS is put in a wall outlet

(commercial power), the UPS starts feeding power at the starting time of the scheduled operation.

Cautions (battery replacement)

Do not short the battery with a metal thing.

● Doing so may cause a burn or fire.

● A dead battery keeps some current remaining.

Do not toss a battery into the fire. Do not try to break a battery.

● The battery may explode or dilute sulfuric acid may leak.

Do not use any batteries unless otherwise specified.

● Doing so may lead to a fire.

● Battery model: BP100XR

Do not use a new battery and an old battery all together

● Dilute sulfuric acid may leak

Do not drop the battery or do not give strong impact on it.

● Dilute sulfuric acid may leak.

Do not replace the battery near the place where there is flammable gas.

● A spark may occur when connecting the battery, and lead to a fire.

Replace a battery on a structurally sound base.

● Hold the battery securely with your both hands to avoid dropping.

● Not doing so may cause injury due to failing, burns, or liquid (acid) leakage.

Do not carry the replaced battery pack upside down.

Directions for safe use

Notes

Charge the battery (for at least 8 hours) immediately after purchasing the UPS.

● If you do not use your UPS for a long time after purchasing, the battery characteristic may deteriorate and

become unusable.

● After putting the AC Input Plug of the UPS in a wall outlet (commercial power), the battery is automatically

charged.

When you want to store the UPS, charge the battery for at least 8 hours.

● In a case where you do not use the battery, it discharges spontaneously and gets into over discharge status

after it is left for a long time. The backup time may become shorter or the battery may become unusable

● The expiration date of the battery installed in the UPS is 6 months after charging it for at least 8 hours.

● If you want to store the battery longer than 6 months, put the AC Input Plug of the UPS in a wall outlet

(commercial power) for at least 8 hours before the expiration date is exceeded.

● Press the stop switch of the UPS for storage.

Do not reverse the connection of Line/Hub Side and Modem/TA/PC Side of the Network Line Surge Protection.

● If a protection circuit failure occurs, the line side (telephone/ISDN line) may be damaged.

Do not give a short between the output lines of the UPS, as well as a ground fault between the output lines and the ground.

● The UPS may fail.

Do not put the AC Input Plug of the UPS in the Power Supply Output Receptacle of the UPS.

● The UPS may fail.

Turn off the UPS before opening a circuit breaker or removing the AC Input Plug from a wall outlet (commercial power). If you cannot stop the UPS for some reason, bring the UPS to automatic stop through the UPS monitoring software, which requires the least backup time.

● You can start the backup mode of the UPS simply by cutting off commercial power to the UPS and keep

devices running until the battery gets discharged. That way when you repeat charges and discharges many times, the life expectancy of a battery pack becomes extremely short. The less you repeat charges and discharges, the longer the life expectancy of the battery will become.

Do not connect a page printer to the UPS.

● In a case a page printer is connected to the UPS, the amount of output current often exceeds the current

output capacity of the UPS in the commercial power operating mode, and that may lead to the UPS to put out a feed power as it is (bypass mode).

● The peak current of the page printer is large so that it may be detected as an overcurrent.

Do not perform a withstand voltage test.

● The power input circuit has a built-in surge absorber element. A withstand voltage test may break it.

● When performing an insulation resistance test, select the 250 VDC range.

Directions for safe use

Notes

Recycling and Discarding the Battery

● The UPS has a lead acid battery. The battery is recyclable, and precious resource. We need

your cooperation in recycling the old batteries; the batteries you replace with a new battery, and the batteries you used to discard.

● For further information on recycling and/or discarding of batteries and UPS, please contact us;_________.

Installation and storage places

● Do not install or store the UPS in a place exposed to direct sunlight.

The rise of temperature may cause the battery to deteriorate and become unusable.

Explanations

Usual operating method

● You may keep the UPS running without making a stop, or you may turn off the UPS at each time when the

devices connected the UPS is turn off. You can choose either of two ways at your convenience.

● Putting the UPS to a wall outlet (commercial power) starts charging the battery.

Terminating the backup mode

● In a case where power failure continues longer, the battery keeps its discharging and finally the UPS stops

sending power. Before that, turn off your computer in the usual manner (including data backup).

Reboot

● If the battery discharges completely during a power failure, the UPS stops. After the recovery from a failure

of the power supply (for example, power failure), the UPS automatically restarts and starts to feed power. If you do not want to run the devices connected to the UPS, keep turning the devices off.

● The UPS monitoring software permits to disable automatic restart.

Scheduled operating mode through the UPS monitoring software

● When performing scheduled operating mode in which the UPS is turned off and the commercial power is cut

off by using a circuit breaker at the same time, specify a less than 3 months shutdown. In a case that you specify the shutdown longer than 3 months, the internal timer will be reset and the scheduled operating mode will not work. Notice that a shutdown should reduce to approximately half where the battery is dead. In a case where a shutdown exceeds 3 months, the UPS starts to feed commercial power and you can get the UPS running by pressing the Start switch. However, if the battery is already dead, you may not be able to start the UPS. Then replace the battery according to "6-2 Replacing the battery" on page 33.

Installing a rack

● For safety installation, placing a rail or steel plate is recommended to support the weight of the USP.

● The weight of the UPS

BU100XR2: 19kg BU200XR2: 12kg (main unit) MB100XR2: 26kg (add-on battery unit) MB200XR2: 26kg (battery unit)

● Place the UPS on the lowest part of lack. When connecting the battery unit and/or adding another battery

unit, be sure to place the battery unit on the lower part of main unit.

2. How to calculate an input current roughly

You can calculate an input current roughly before turning on the UPS.

• Calculate the total electric energy (VA) of the devices linked to the UPS. Get volt-ampere (VA) of the devices connected to BU200XR2. You may refer to their rating plate, specification sheet, and instruction manual. Finally sum the amount of VA In a case where VA is described as W (watt), perform mathematical calculations; W ÷ 0.6 = ___VA. In a case where VA is described as A (ampere), perform mathematical calculations; A X 100 = ___VA.

• In the event that resultant total volt-ampere exceeds 1500VA, change the AC Input Cable.

Explanation

When reconnect AC Input Cable to BU200XR2, align "L,N,G" printed on the right side of AC Input Terminal, which is on the rear side of BU200XR2, with "L,N,G" printed on AC Input Cable.

2-4 Connecting a battery unit (BU200XR2)

When connecting "Battery Connecting Cable" included with the battery unit between "Battery Connector" of the main unit and "Battery Connector" of the battery unit, it may make a spark, however, that is no problem. After putting "AC Input" plug in, the connection lamp on the front panel of the battery unit will light up.

2-8 Checking the operation

Cautions

If the input plug is removed while the UPS is running, never touch its metal part.

● Doing so may cause an electric shock.

● A leak current of the UPS is less than the value of the safety standard (leak current: 1mA).

However, A leak current increases due to the devices linked to the UPS. So never touch the metal part of the input plug.

Prior to use of the UPS, follow the steps below to check whether backup function works. (This operational check of removing the "AC Input Plug" from the wall outlet is carried out on the assumption that power failure would occur.)

(1) Connect your PC and other devices to the UPS, and then put the AC Input Plug of the UPS in a wall outlet

(commercial power).

(2) Press the Start switch to get the UPS running.

Bring all devices linked to the UPS into operation at the start of the operation. (Including devices connected to the AC outlet of your PC.)

Operate the devices in a way that power to the devices may be off any time.

(3) Under this condition, check the indicator lamps of the UPS.

2-9 Charging the battery

When you put the AC Input Plug of the UPS in a wall outlet (commercial power), a battery charges automatically starts and the battery will be fully charged within 8 hours. (A battery charges when the UPS is used or not)

● The UPS has been charged prior to shipment, however, the backup time may be shorter when using the UPS for the first time due to spontaneous discharge. We recommend to charge the UPS before using it.

2-10 Measuring the backup time

After "2-8 Checking the operation" is complete, you can start an actual operation, however, we recommend measuring the actual backup time of the UPS in your surroundings before starting the initial operation. That gives you a guideline for the battery check.

See also "5-1 Measuring method of the backup time" on page 32.

Page 26

3. Operating the UPS

3-1 Precautions and notes on operation

During the operation, follow the do's and don'ts below.

Cautions (use)

● The continuous operation of the UPS may cause a fire.

● For further information on how to inspect the battery, see "6. Maintenance and inspection" on

page 33.

Ambient Estimated life

temperature expectancy

20°C4 to 5 years 30°C2 to 2.5 years

● A continuous operation under the abnormal conditions may cause a leakage of current or fire.

● If you notice the abnormal conditions, never operate the UPS and contact the distributor from which you purchased your UPS or us for inspection and repair.

● Your UPS must permit to remove AC Input Plug from a wall outlet (commercial power) instantly at the onset of a failure.

* The left table shows the estimated life expectancy of a

battery pack on the ground that the battery is used in the usual way. They are not the warranty period.

Before maintaining devices connected to the UPS, turn off the UPS and remove the AC Input Plug from a wall outlet (commercial power).

● Even if you remove the AC Input Plug during the operation of the UPS, the backup function of the UPS keeps feeding power through the power supply output receptacle of the UPS.

● In a case where the scheduled operation is ON and the AC Input Plug of the UPS is put in a wall outlet (commercial power), the UPS starts feeding power at the starting time of the scheduled operation.

When the input plug accidentally become removed while the UPS is running, never touch the metal part of the input plug.

● Doing so may cause an electric shock.

● A leak current of the UPS is less than the value of safety standard (leak current: 1mA) how-

ever, the leak current may increase due to the devices connected. Therefore, never touch the metal part of the input plug.

Do not place things on the UPS or do not drop metal things into the UPS.

● Doing so may cause distortion and/or damage to the top case of the UPS or an internal circuit failure, which may leads to a fire.

Do not place the UPS in an enclosed space or put a cover over the UPS.

● Doing so may lead to an abnormal overheat or fire.

Do not wet or spill water on the UPS

● Doing so may cause an electric shock or fire.

Page 27

3. Operating the UPS

Cautions (use)

Do not insert a metal thing into the Power Supply Output receptacle of the UPS.

● Doing so may cause an electric shock.

Do not insert metal things into the battery connector or add-on battery connector.

● Doing so may cause an electric shock.

Do not use the UPS where the maximum temperature exceeds 40°C.

● The battery becomes week rapidly, and may lead to a fire.

● Doing so may cause a failure or malfunction of the battery.

Notes

Before cutting out commercial power by turning off the breaker or disconnecting the AC Input Plug, stop the UPS. If you cannot turn off the UPS, it is recommended to automatically stop it in the minimum backup time using the UPS monitoring software.

● When you stop commercial power, the Battery mode starts. If you repeat changing and discharging in a way in which you stop commercial power and discharge the battery completely, the life of the battery decreases extremely. The less the amount of charging and discharging is, the les the affect on the life becomes.

4-3 Description of the auto battery tests

This UPS provides automatic checking functions whether a battery needs replacing and/or the internal circuit is at fault. (You do not have to perform the tests by yourself.) The tests are performed within 4 to 24 hours after the AC Input Plug is put in a wall outlet (commercial power) on the ground that the UPS continues in usual service conditions. The test will be subsequently repeated every 4 weeks.

In a case where you remove the AC Input Plug from a wall outlet (commercial power) while the UPS is turned off, the test period will be reset. When the UPS detects that the UPS is turned off, the battery needs replacing, or the UPS enters in the backup mode within 4 hours after starting the test due to irregularities in the mains supply, the test will not be performed.

In a case where you prefer to "disable the auto battery test," you can change the setting through the UPS monitoring software. For further information, refer to the online help of the UPS monitoring software. (The factory-shipped setting is "Enable the auto battery test.")

(1) When the auto battery test starts, your UPS enters automatically

into the battery mode. (No beep sounds.) After the completion of the battery replacement test, the UPS automatically goes back to usual service conditions.

(2) If the Error Lamp goes on and beeper sounds, take necessary

countermeasures according to "C. Failure (display and beep when a failure occurs in devices)" of "3-3 Beep and display" on page 27.

On the ground that the UPS is in usual service conditions, a self-test is performed automatically within 4 to 24 hours after the AC Input Plug is put in a wall outlet (commercial power). In a case you turn off the UPS everyday, select the "Don't perform battery auto test" setting. In a case you select "Perform battery auto test" setting, the estimated life expectancy of a battery pack will become shorter as the battery test is repeated everyday.

5. Measuring the backup time

5-1 Measuring method of the backup time

Cautions

When the input plug accidentally become removed while the UPS is running, never touch the metal part of the input plug.

● Doing so may cause an electric shock.

● A leak current of the UPS is less than the value of safety standard (leak current: 1mA) however,

the leak current may increase due to the devices connected. Therefore, never touch the metal part of the input plug.

(1) Put the AC Input Plug of the UPS in a wall outlet (commercial power) and change the battery

for at least 8 hours. (You may turn on the Start switch and get devices linked the UPS running.)

(2) Turn on all devices connected the UPS.

(Including devices connected to the AC receptacle of your PC.)

(3) Remove the AC Input Plug of the UPS and check a backup time.

* The backup time you measure for the first time after purchase is the "initial value of the backup

time." Initial value of the backup time: minutes seconds

5-2 Estimated backup time

The backup time varies depending on the capacity of devices connected to the UPS. After calculating the total capacity of devices connected to the UPS, refer to the graph of the backup time to obtain an estimate initial value of the backup time.

(1) Convert the total capacity (power consumption) of devices linked to the UPS to watts.

Check the unit of these devices connected to the UPS. There are 3 units: VA, A, and W Example 1) 100VAC, 50/60Hz, Example 2) 100VAC, 50/60Hz, Example 3) 100VAC, 50/60Hz, For the devices with the units of VA and A, convert VA and A to W. See the right table for the conversion.

(2) Sum up the values converted in W and obtain

the total capacity of the devices connected to the UPS.

(3) Obtain the initial value of the backup time for

the total capacity of the devices connected to the UPS from the graph on the right.

8-2 When performing the auto shutdown

processing by the UPS monitoring software

The preinstalled UPS monitoring software allows you to save files automatically and perform shutdown processing of your PC when a power failure occurs. However, the time between the occurrence of a power failure and the completion of the shutdown of your PC must be within the backup time measured in "5-1 Measuring method of the backup time" on page 32. For further information on the explanation and operation, refer to either the UPS monitoring software instruction manual or the online help about the UPS monitoring software.

Explanation

Scheduled operating mode using the UPS monitoring software

● When making the settings of the scheduled operating mode, which turns off the UPS and opens the circuit breaker to shut off commercial power at the same time, you must set the starting time shorter than 90 days after the commencement of this scheduled operating mode. If you make the settings of the scheduled operating mode longer than 90 days, the internal timer is forced to reset and the scheduled operation become disable. Notice that a dead battery gives you only about half of the setting time; approximately 45 days. If you make the setting of the scheduled operating mode longer than 90 days, you can press the Start switch and get the UPS running, however, in case where the battery is dead, you may not be able to get your UPS running again. When you are unable to get your UPS running, replace the battery according to "6-2 Replacing the battery" on page 33.

How to get your UPS running where it is set in scheduled operating mode through the UPS monitoring software

● When you want to get your UPS running by pressing the Start switch under circumstances where your USP is dead as it is set in the scheduled operating mode, just press the Start switch for at least 0.5 second and your UPS enters into the usual service conditions after 15 seconds.

When you want to make a stop of your UPS, just press the Stop switch for at least 2 seconds.

Page 46

8. Using the UPS monitoring software and contact signal I/O

Explanation

Auto restart after the completion of the OS shutdown processing through the UPS monitoring software

● For certain PC models (*1), they automatically restart immediately after the completion of the OS shutdown processing through the UPS monitoring software in the event of a power failure. In this event, the UPS will probably make a stop during or after the restart of the PC, and files and hard disk mounted in your PC may be destroyed. You can avoid this problem by disabling POWER MANAGEMENT in the BIOS settings of your PC. * 1) certain PC models: It is reported that MICRON's Millennia Mme likely brings about the problem.

● When the PC does not startup automatically, select a "System startup at power return" setting

(such as "Restore On AC/Power Loss) at the BIOS settings and change to a "Startup power returned system" setting (such as "Power On"). Individual BIOS setting method and/or display may differ depending on the PC. For more information, consult your instruction manual or contact your technical support center.

● When considering a system with automatic startup at power return, choose a PC that satisfied

the following conditions. For more information on PC operation at input power on, consult your instruction manual or contact the PC technical suppoprt center.

The PC starts up at input power on without depressing the power switch

Automatic shutdown of UPS

● Due to RS232C signal voltage from PC, UPS may sop earlier than system shutdown time set

by automatic shutdown software after completion of OS shutdown.

After the input, press the Enter key. Enter the serial port number, which is connected to the UPS, after PORT=. (1 or 2)

8-5 Details on Contact Signal I/O

You can develop your unique system based on the following specifications to automate the process at a power failure. You can perform power-failure processing by allowing the system to detect the backup signal and also perform system shutdown processing by allowing the system to detect the battery low signal. Also, by inputting the backup stop signal from the system, you can stop the UPS with an enough battery amount to prepare for the next occurrence of a power failure.

1. Signal output

The UPS has two kinds of output signals. The output circuit takes a form of an open collector circuit using a photo coupler (a kind of electronic switch).

● Backup signal output: BU BU stays ON during a power failure.

● Battery low signal output: BL BL goes ON (LOW) when the current remaining of the battery is getting flat in the backup mode operation. BL actually goes ON (LOW) when at least 1.5 minutes before the UPS makes a stop. The time may be less than 1.5 minutes where the battery becomes deteriorated and the backup time becomes shorter.

2. Input of the UPS Stop Signal (BS)

● Acceptance of stop signal only in the time of backup mode You can stop the UPS by transmitting a voltage signal (High) that continued more than 0.01 sec. (10 m sec.) from the outside of the UPS. The stop signal is acceptable only in the time of backup mode.

● Acceptance of stop signal both in the usual service mode and in backup mode. You can stop the UPS by transmitting a voltage signal (High) that continues more than 10 sec. from the outside of the UPS.

Page 48

8. Using the UPS monitoring software and contact signal I/O

3. Connection to the system

Please design a cable wiring by yourself. (For the samples of the circuit, see "7. Example of connection: the Contact Signal I/O Circuit" on page 46.)

4. Contact Signal I/O ratings

● Signal output (BU and BL)

Photo coupler ratings Applied voltage: 24VDC or less Maximum current: 10mA

● Signal input (BS)

Input voltage: HIGH 5 to 12VDC, LOW 0.8VDC or less

• BS is acceptable both in usual service mode and backup mode. BS becomes unacceptable when voltage signal continues over 10 seconds.

• BS is acceptable only in backup mode. BS becomes unacceptable when voltage signal continues over 0.01 second (10ms). * For further information on the setting of the UPS Stop Signal, see "9-1 Functions that can be set/

change from the UPS” on page 47.

● The factory- setting is "Accept only during Battery mode." Do not change the factory-setting except when the UPS is under the following conditions. Also do not change the factory-setting when using the supplied UPS monitoring software, PowerAssistant.

• If you change the setting of "Accept both during line mode and during Battery mode." The UPS can make

an accidental stop at the startup of the PC, which may break files and others. It is reported that the problem occurs when an expansion SCSI board is added to Sony VAIO R series PC.

• Do not start up the PC during the battery mode. The UPS will make a stop at the startup.

● Changing the factory-setting When you always want to restart your system as an automatic system, for examples, Windows NT's UPS service that enables you to perform auto save processing, the contact signal that enables you to configure a shutdown system, and others, change the settings of "Accept both during line mode and during battery mode."

• In a case you want to run the WindowsNT UPS Service, you will always need to change the factory-

settings, otherwise WindowsNT's power reset and auto restart functions become out of control. These problems usually take place when irregularities in the mains supply are restored before the UPS comes to a stop, which follows a power failure shutdown.

• When you change the setting, the UPS may stop at the startup of the PC, however, it depends on PC

models. Before beginning the first run of the system, check whether the UPS comes a stop at the startup of your PC and go through a series of steps below.

* Checking steps

1. Remove the AC plugs of the devices such as PC and peripheral devices from the Power Supply Output Receptacles of the UPS.

2. Put the plugs of PC and peripheral devices in a wall outlet (commercial power).

3. Connect the serial port of PC and the UPS.

4. Start up PC. Check whether the UPS comes to a stop or not. * In the case where the UPS keeps running, then you may select the "Accept both during line mode and

during battery mode" setting. In the case where the UPS come to a stop, select "Accept only during Battery mode" setting before use.

* Check whether there are no problems with the UPS, and put the AC plugs of PC and peripheral

devices. For further information on the connection, see "2. Installation and connection" on page 12.

● Setting steps

1. Unplug the UPS and let it to a standstill. Press the Start switch for at least 0.5 second while pressing and holding Stop switch.

2. The AC Input Lamp blinks and the Bypass Mode Lamp or the Battery Mode Lamp goes on.

3. Under the condition, press and hold the Start Switch again for at least 0.5 second. Either of the Bypass Mode Lamp or the Battery Mode Lamp turns on, and let the setting change.

• The Bypass Mode Lamp lights up:

It lets the UPS accept the signal both during line mode and battery mode. You can bring the UPS into a standstill by the voltage signal, which continues at least 10 seconds.

• The Battery Mode Lamp lights up:

It lets the UPS accept the battery mode only.

You can bring the UPS into a standstill by voltage signal, which continues at least 0.01 second (10 ms).

* Factory-setting: Accept BS signal only during Battery

mode.

4. When the desired setting is displayed, press and hold the Stop switch for at least 2 seconds, and then the setting is completed.

9-2 Functions that can be set/change from the

UPS monitoring software

1. Beeper ON/OFF setting

ON : The beeper sounds when an alarm is necessary.

OFF : Let the beeper disable.

* Factory-setting: ON

2. Auto battery test ON/OFF

ON : The battery test is automatically executed every 4 weeks.

If the test decides that the battery needs replacing, the UPS generates a replacement alarm.

OFF : The battery test, which is executed automatically at intervals of 4 weeks, comes to a standstill.

Set the test OFF in the cases where you want to let the automatic battery test and battery mode come a standstill.

* Factory-setting: ON

3. Auto restart ON/OFF

ON : The UPS startup automatically and starts to feed power at the time when the commercial power is

restored. It always takes place after the UPS is shut down through UPS monitoring software or the contact signal in the event of power failures.

OFF : The UPS will not startup automatically at the time when the commercial power is restored following

the shutdown of the UPS through UPS monitoring software or the contact signal. You only can start up the UPS manually by pressing the Start switch.

* Factory-setting: ON

9. EChanging the setting of the functions

Problems

The UPS does not operate, or the AC Input Lamp does not go on.

Battery mode does not function. The devices connected the UPS comes to a stop when a power failure occurs.

The UPS enters into the battery mode frequently

The display of devices linked to the UPS is abnormal.

• Jitter of the display

• While lines of the display

The Connection Capacity Exceeded Lamp goes on.

The Battery Replacement Lamp goes on.

The Error Lamp goes on.

No output despite operation mode indication is normal (For BU200XR2 only)

Remedies

The AC Input Plug is not put in a wall outlet.

• Check whether the AC Input Plug is certainly put in a wall outlet. The red button pops up from the AC Input Overcurrent Protection. (BU100XR2) The AC Input Overcurrent Protection is OFF. (BU200XR2)

• It is suspected that too many devices are connected to the UPS, or the devices developed a short circuit. Reduce connected devices or check the fuses of devices. In a case where the devices connected to the UPS are normal, then disconnect all of the devices from the UPS, turn on the Red button of the AC Input Overcurrent protection and put the AC Input Plug in a wall outlet (commercial power). In case that the AC Input Overcurrent Protection still remains OFF, you may assume a failure.

It is suspected that the battery is not changed fully.

• Turn off every device linked to the UPS and charge the UPS for at least 8 hours. After the completion of the battery charge, bring the UPS and every device linked to the UPS to a standstill, and turn on the Start switch again. Remove the ACA Input Plug from a wall outlet (commercial power). In case where the battery mode does not function at all, replace the battery pack as the life of the battery expired.

Voltage fluctuations at low voltage level occur frequently or the voltage contains noises, which bring about an extreme distortion of the voltage waveform.

• Change the wall outlet (commercial power) to which you put the plug of the UPS. Plug the UPS in other wall outlet (commercial power) at some distance away from the devices that consumes large power.

• The similar problem may occur also when you put many devices in a plug strip or extension cord plugged in the UPS as well.

It is assumed that a noise occurred inside of the UPS causes jitter and white lines of the display.

• Ground the UPS and every device linked to the UPS. Put them in a grounding-type receptacle (commercial power), or a receptacle with a grounding terminal.

• The problems may occur where a power cord is too long, some of the power cords are adjacent to one another, or the UPS and devices to linked to the UPS are adjacent one another. Change the placement of the UPS and devices

• If the UPS or devices connected to the UPS are placed in a metal rack, ground the rack.

The total capacity of the devices connected to the Power Supply Output Receptacles of the UPS exceeds the rated capacity; 1 KVA/700W for BU100XR2 or 2KVA/

1.4KW for BU200XR2.

• Reduce connected devices.

The auto battery test indicated that the life of the battery expired.

• The battery mode cannot be functioned and therefore replace the battery pack.

An error or faulty has occurred in the UPS.

• Bring the UPS and the devices connected to the UPS to a standstill. Remove every device connected to the UPS, and then turn on the Start switch of the UPS. In the case the UPS restores in usual service condition, it is assumed that the some of the devices linked to the UPS developed a short circuit. Check devices. In the case where the problem still persists, bring the UPS to a standstill for one hour, and then restart the UPS. In a case where the UPS restores in usual service condition, it is assumed temperature rise, then improve ventilation around the UPS. Finally if you cannot solve the problem after one hour, it is assumed that the UPS may be out of order and need repair. Contact us:

It is assumed that output fuse is burnt.

• Stop operation of UPS and check the output fuse. Replace the fuse if it is burnt.
