Safety precautions
Notes
When moving the unit from a cold place to a warm place, leave it for several hours
before using it.
● If the unit is promptly turned ON after being moved to a warmer place, condensation may form inside the
unit and cause it to fail.
Charge the battery for at least 8 hours soon after purchasing the unit.
● If you do not use the unit for a long time after the purchase, the battery may deteriorate and the battery may
become unusable.
● To charge a battery, connect the AC input plug of the unit to a wall outlet (commercial power).
When storing the unit, charge the battery for at least 8 hours and turn OFF the power switch.
● Even if the unit is not used, the battery gradually discharges, and if it is left for a long time, it goes into an
over discharge state.
The backup time may become shorter or the battery may become unusable.
● We recommend keeping the temperature 25°C or less when storing the unit for long periods of time.
Connect the unit’s AC input plug to a wall outlet (commercial power) for at least 8 hours at the following
intervals:
- Every 6 months when storage temperature is 25°C or less
- Every 2 months when storage temperature is 40°C or less
● Turn off the power switch of the unit during storage.
Do not short the output lines of the unit to each other, and do not short the output
lines to the ground.
● The unit may fail.
Do not connect the AC input plug of the unit to its Power Supply Output Receptacle
during the Battery Mode.
● The unit may fail.
Do not connect a page printer (such as a laser printer) to the unit.
● The unit repeatedly and frequently switches between Commercial Power Mode and Battery Mode, which
may shorten the life of the battery.
● The page printer has a large peak current, so an excess of the connection capacity or a power failure due to
instantaneous voltage drop may be detected.
Check system operation beforehand if the unit is used in combination with a device
whose power supply frequency fluctuates widely, such as a personal electric
generator.
● The unit automatically recognizes the input power frequency when input power is supplied.If the unit is
connected when the input power frequency is not stable at the rated level, the unit may misidentify the
power supply frequency and may fail to operate normally. (If the unit is in operation, changing from commer-
cial power supply to another power supply source, such as generating equipment, will cause no problem.
Set the generator's frequency to the same level as that of the commercial power supply.)
Do not install or store the unit in a place exposed to direct sunlight.
● The rise of temperature may cause the built-in battery to deteriorate rapidly and become unusable.
Do not perform a withstand voltage test.
● The input circuit has a built-in surge absorption device. A withstand voltage test may break it.
● When performing an insulation resistance test, use the 400V DC range.
Before stopping the commercial power to the unit, turn OFF the power switch of the unit.
● The unit enters Battery Mode when commercial power is stopped. If you frequently use the unit in Battery
Mode, the battery life may be significantly shortened.

Notes
Check the operation beforehand if the unit is used in any mode other than “Output
200V mode”.
● In Battery Mode, the maximum voltage (peak voltage) of output (rectangular wave) may be lower than the
maximum voltage in Commercial Power Mode. For this reason, some connected devices may fail to operate
normally.
If this unit is used with an inductive device such as a coil or motor, check the operation
beforehand.
● With some types of devices, the effect of inrush current may cause this unit to stop operating properly.
In the event you transfer or sell this unit to a third party, please include all of the
documentation that came with the unit. This is to ensure that the unit is used in line
with the conditions described in the included documentation.

Explanation
Usual operation
● You may either leave the power switch of the unit ON (operation status) or turn it OFF each time when
stopping the connected system. Choose whichever operation method is more convenient. We recommend
turning OFF the power switch when you do not use connected devices for a long time.
●
The battery can be charged once the AC input plug of the unit is connected to a wall outlet (commercial power).
Quitting Battery Mode
● If a power failure lasts for an extended period of time, the battery discharges and power output from the unit
stops. Shut down your computer after performing appropriate procedures (for example, saving data) while
the unit is still supplying power.
Rebooting
● If the battery discharges completely during a power failure, the unit stops. After recovery from the power
failure, the unit automatically restarts and supplies power. If you do not want to restart the connected
devices, turn OFF the power switch of either the unit or the connected devices.
See also
Setting switch 2 can be used to select whether or not auto restart is performed. See Page 43
Scheduled operation using the UPS monitoring software
● When performing scheduled operation in which the UPS is stopped and a device such as a breaker is used
to stop the UPS at the same time that commercial power stops, specify a period of no more than 3 months for
the start of the next operation.
If you specify a period longer than 3 months, the internal timer is reset and the scheduled operation does not
start. Note that this period reduces to approximately half when the battery is dead. If a period of 3 months is
exceeded, you start operation by supplying commercial power and pressing the start switch. However, if
the battery is dead, you may not be able to start operation.
In this case, replace the battery according to the instructions in “6-2 Replacing the battery” on page 54.

Caution (for installation and connection)
Do not block the air vents on the unit. The BU1002SW has air vents on the
front, side and back, while the BU3002SW has air vents on the front and back.
● Doing so will cause the internal temperature to rise, which may cause the unit to fail and the
battery to deteriorate.
● Leave at least 5 cm of space between the vent and the wall.
Do not connect a standalone transformer such as a voltage transformer
or isolating transformer to the output side.
● Overcurrent may damage the UPS.
● There is no problem in connecting a transformer to the input side.
Do not connect devices that cannot be used with commercial power supply.
● When the unit’s power switch is turned ON and an error occurs with the connected device,
bypass operation is performed and commercial power supply is supplied as is to the con-
nected devices.
Do not connect devices with rated voltage of 200 to 240 VAC or higher.
● The rated output voltage of this device is 200 to 240 VAC.
● Overcurrent may damage the connected devices.
When in use, make sure the output terminal block cover is attached.
Do not turn ON the power switch when it is detached.
● Voltage is applied to the output terminal block when the power switch is ON, which can result
in electric shock.
For PLUGGABLE EQUIPMENT, the socket-outlet shall be installer near
the equipment and shall be easily accessible.
Notes
When moving the unit from a cold place to a warm place, leave it for several hours
before using it.
● If the unit is promptly turned ON after being moved to a warmer place, condensation may form inside the
unit and cause it to fail.

2. Installation and connection
Notes
Do not short the output lines of the unit to each other, and do not short the output
lines to the ground.
● The unit may fail.
Do not connect the AC input plug of the unit to its Power Supply Output Receptacle
during the Battery Mode.
● The unit may fail.
Do not connect a page printer (such as a laser printer) to the unit.
● The unit repeatedly and frequently switches between Commercial Power Mode and Battery Mode, which
may shorten the life of the battery.
● The page printer has a large peak current, so an excess of the connection capacity or a power failure due
to instantaneous voltage drop may be detected.
Check system operation beforehand if the unit is used in combination with a device
whose power supply frequency fluctuates widely, such as a personal electric
generator.
● The unit automatically recognizes the input power frequency when input power is supplied.If the unit is
connected when the input power frequency is not stable at the rated level, the unit may misidentify the
power supply frequency and may fail to operate normally. (If the unit is in operation, changing from commer-
cial power supply to another power supply source, such as generating equipment, will cause no problem.
Set the generator's frequency to the same level as that of the commercial power supply.)
Do not install or store the unit in a place exposed to direct sunlight.
● The rise of temperature may cause the built-in battery to deteriorate rapidly and become unusable.
Do not perform a withstand voltage test.
● The input circuit has a built-in surge absorption device. A withstand voltage test may break it.
● When performing an insulation resistance test, use the 400VDC range.
Before stopping the commercial power to the unit, turn OFF the power switch of the
unit.
● The unit enters Battery Mode when commercial power is stopped. If you frequently use the unit in Battery
Mode, the battery life may be significantly shortened.
Check the operation beforehand if the unit is used in any mode other than “Output
200V mode”.
● In Battery Mode, the maximum voltage (peak voltage) of output (rectangular wave) may be lower than the
maximum voltage in Commercial Power Mode. For this reason, some connected devices may fail to oper-
ate normally.
If this unit is used with an inductive device such as a coil or motor, check the operation
beforehand.
● With some types of devices, the effect of inrush current may cause this unit to stop operating properly.

2. Installation and connection
2-5 Charging the battery
When you connect the AC input plug of this unit to a wall outlet (commercial power), the battery charg-
ing automatically starts regardless of whether the power switch is ON or OFF, and it is fully charged
within 8 hours. (When an additional battery unit is connected, the charging time is 24 hours.)
● This unit has been charged prior to shipment. However, the backup time becomes shorter when using it for
the first time due to spontaneous discharge. We recommend charging this unit before using it.
● If you do not perform the initial backup time measurement described below in “2-6 Measuring the initial
value of backup time”, proceed to “3. Operation”. → Page 34
2-6 Measuring the initial value of backup time
● When you measure the backup time initial value of the unit in your environment, this value can be used as
a guide when checking the battery and deciding the UPS monitoring software setting values.
See also
"5. Measuring the backup time" → Page 51
2-7 Recharging the battery
The battery is discharged completely when the backup time is measured, so you need to recharge it before
using the UPS.
● You can use connected devices while recharging the battery, but the backup time when a power failure
occurs is shorter until the battery is fully charged.
(If a power failure occurs immediately after the start of charging, backup stops immediately.)

Charge the battery as described in "2-5 Charging the battery."
Preparation for starting operation is now complete.

3-1 Precautions and notes for operation
Caution (for use)
Never touch the metal part of the input plug if it is disconnected while the
unit is operating.
● Doing so may result in electric shock.
● The leak current of this product itself is less than the value of the safety standard (leak current:
1 mA). However, because connected equipment causes the leak current to increase, you
must never touch the metal part of the input plug.
● When the unit is operating, voltage is generated in the metal parts of the input plug via
capacitors in the internal circuit, regardless of the elapsed time.
Do not allow the unit to come in contact with water.
● Doing so may cause an electric shock or a fire.
● If the unit becomes wet, stop using it and have it inspected and/or repaired.
For repair, contact us:____________
When the battery is dead, replace it immediately or stop using the unit.
● Continuing the use of it may cause a fire.
Ambient temperature Expected life
20°C
4 to 5 years
* The values in the table are the expected life under standard
use conditions and are not guaranteed.
30°C
2 to 2.5 years
Using a dry cloth, periodically wipe the dust from the AC input plug, power
supply output receptacles and output terminal block.
● Accumulated dust may cause a fire.
Do not use the unit in a closed place and do not cover the unit.
● Doing so may cause abnormal heating or a fire.
If you notice abnormal sound or smell, smoke, or leakage from the inside,
immediately turn OFF the power switch and disconnect the AC input plug
from a wall outlet (commercial power).
● Using the unit under such conditions may cause a fire.
●
If you notice such a condition, stop using the unit and contact us at _____ for inspection and repairs.
● Use the unit under the conditions in which you can immediately disconnect the AC input plug
from a wall outlet (commercial power) in the case of an abnormal event.
If fluid leaks from the unit, do not touch the fluid.
● Doing so may cause blindness or burns.
●
If the fluid contacts your eyes or skin, wash it out with lots of clean water and consult your doctor.
Do not place objects on the unit that are 25 kg or heavier, and do not drop
metal objects onto the unit.
● Doing so may cause distortion/damage to the case or a failure of the internal circuit, which
may cause a fire.

3. Operation
Notes
Before stopping the commercial power to the unit, turn OFF the power switch of the unit.
● The unit enters Battery Mode when commercial power is stopped. If you frequently use the unit in Battery
Mode, the battery life may be significantly shortened.
Take measures for handling unforeseen accidents, such as data backup and system
redundancy.
● The output may stop when there is a circuit failure in the UPS.
Explanation
Usual operation
● You may either leave the power switch of the unit ON (operation status) or turn it OFF each time when
stopping the connected system. Choose whichever operation method is more convenient. We recommend
turning OFF the power switch when you do not use connected devices for a long time.
● The battery can be charged once the AC input plug of the unit is connected to a wall outlet (commercial
power).
Quitting Battery Mode
● If a power failure lasts for an extended period of time, the battery discharges and power output from the unit
stops. Shut down your computer after performing appropriate procedures (for example, saving data) while
the unit is still supplying power.
Rebooting
● If the battery discharges completely during a power failure, the unit stops. After recovery from the power
failure, the unit automatically restarts and supplies power. If you do not want to restart the connected de-
vices, turn OFF the power switch of either the unit or the connected devices.
See also
Setting switch 2 can be used to select whether or not auto restart is performed. See Page 43
Scheduled operation using the UPS monitoring software
● When performing scheduled operation in which the UPS is stopped and a device such as a breaker is used
to stop the UPS at the same time that commercial power stops, specify a period of no more than 3 months for
the start of the next operation.
If you specify a period longer than 3 months, the internal timer is reset and the scheduled operation does
not start. Note that this period reduces to approximately half when the battery is dead. If a period of 3
months is exceeded, you start operation by supplying commercial power and pressing the start switch.
However, if the battery is dead, you may not be able to start operation.
In this case, replace the battery according to the instructions in “6-2 Replacing the battery” on page 54.

5. Measuring the backup time
5. Measuring the backup time
5-1 How to measure backup time
Caution
Never touch the metal part of the input plug if it is disconnected while the
unit is operating.
● Doing so may cause an electric shock.
● The leak current of this product itself is less than the value of the safety standard (leak current:
1 mA). However, leak current increases due to connected equipment. Therefore, never touch the metal
part of the input plug.
● When the product is operating, voltage is generated at the metal part of the input plug via capacitors in
the internal circuit regardless of elapsed time.
(1) When the AC input plug is connected to a wall outlet (commercial power), the battery automatically starts
charging, taking up to 8 hours to complete (24 hours when an additional battery unit is connected).
(2) Turn ON all devices connected to the power output to be “backed up during a power failure”.
(This includes devices connected to the AC outlet of your computer.)
Operate the connected devices in a way that allows the power supply to be stopped at any time.
● For Windows Server 2003/XP/Me/2000/Windows NT/Linux/Mac:
Perform measurement while the hard drive is stopped.
● For Windows 98/95:
Choose "Shut Down" in Windows and follow the procedure below to shut down your OS.
Choose "Restart in MS-DOS mode" to exit from OS and display the MS-DOS mode screen.
(3) Disconnect the AC Input Plug of the UPS and measure the backup time.
Measure the time until the unit automatically stops and all displays disappear with the plug disconnected.
* The backup time you measure for the first time after purchase is the "initial value of the backup time."
5-2 Estimated backup time
The backup time varies depending on the capacity of connected devices.
After calculating the total capacity of connected devices, refer to the graph of the backup time to obtain an
estimation of the initial value of the backup time. (This is also applied to checking the battery.)
(1) Convert the total capacity (power consumption) of the connected devices to watts (W).
For the indication of connected devices, check your computer and the rear of the display.
The indicator can show values in three different ways: volt-amperes (VA), amperes (A), and watts (W).
Indication
Value
Example 1)
Example 2)
Example 3)
200 VAC, 50/60Hz, 145 W
200 VAC, 50/60Hz, 1.8 A
200 VAC, 50/60Hz, 150 VA
VA
A
× power factor = W
× power factor × 200 = W
For devices that use the VA or A indication, convert the capacity into W. Multiply the value indicated on
devices by the value in the right table for conversion.
(When the power factor is unknown, enter “1”. The power factor usually ranges between 0.6 and 1.)
(2) Add the values converted into W to obtain the total capacity of the connected devices.

5. Measuring the backup time
(3) Calculate the initial value of the backup time for the total capacity of the connected devices from the graph
below.
● Graph of backup time (graph of initial values for products that have not been used)
● The smaller the capacity of connected devices becomes, the longer the backup time becomes.

7．Using the UPS monitoring software and contact signal
Explanation
Scheduled operation using the UPS monitoring software
● When performing scheduled operation in which the UPS is stopped and a device such as a breaker is
used to stop the UPS at the same time that commercial power stops, specify a period of no more than 3
months for the start of the next operation.
If you specify a period longer than 3 months, the internal timer is reset and the scheduled operation does
not start.
Note that this period reduces to approximately half when the battery is dead.
If a period of 3 months is exceeded, you start operation by supplying commercial power and pressing
the Start Switch. However, if the battery is dead, you may not be able to start operation. In this case,
replace the battery according to "6-2 Replacing the battery" on page 54.
Start of operation in scheduled operation using the UPS monitoring software
● To manually start up this unit after it has been stopped by a scheduled operation, turn OFF the power
switch and turn it back ON again.
To stop the unit when it is in operation, turn OFF the power switch.
Auto restart after OS closing processing using the UPS monitoring software
● When a power failure occurs, certain PCs (*1) automatically restart immediately after the OS is shut down
by auto shutdown.
In this case, the UPS stops during or after the restart of the PC, which may damage files and the hard
disk. You can avoid this phenomenon by disabling POWER MANAGEMENT in the BIOS settings of the
PC.
*1) Certain PC: It is known that this phenomenon occurs for MICRON's Millennia Mme.
Precautions when “setting the UPS to stop automatically” after OS shutdown
● If, after a power failure occurs, the power is restored while auto shutdown processing is being performed,
UPS output stops once after the set time elapses. After shutdown processing is complete, do not turn
ON the computer until the UPS has finished restarting.

7．Using the UPS monitoring software and contact signal
7-4 Contact signal
Contact Signal
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 Low battery level signal. Also, by
inputting the backup stop signal from the system, you can stop the UPS with a sufficient battery level to prepare
for the next occurrence of a power failure.
1. Signal output
The UPS has 4 kinds of output signals. The output circuit consists of an open collector circuit using a photo
coupler (a kind of electronic switch).
BU-COM ON when a power failure occurs
● Backup Signal output: BU
BU stays ON during a power failure.
BL-COM ON when the battery is low
● Low battery level signal output: BL
Goes ON when the battery becomes weak during the
Battery Mode.
● Trouble Signal output: TR
TR-COM ON when a power failure occurs
Goes ON when an internal failure of the UPS occurs.
● Battery Replacement Signal output (WB)
WB-COM ON when battery deterioration is detected
Goes ON when the test determines that battery
replacement is necessary due to deterioration.
2. Signal input
BS-COM UPS stops
● Input of the UPS Stop Signal (BS)
Stops the output of the UPS after the time period specified by the “power output stop delay time setting”
has elapsed.
(1) When the "BS signal valid range setting" (setting switch 7 ) is set to OFF:
You can stop the output of the UPS by inputting the voltage signal (HIGH) that lasts at least 10 seconds
from the outside.
(2) When the "BS signal valid range setting" (setting switch 7 ) is set to ON:
You can stop power output by inputting the voltage signal (HIGH) that lasts at least 0.01 second (10
ms) from the outside that is accepted only during backup.

10. Troubleshooting
10. Troubleshooting
Perform the checks shown below if the unit is operating abnormally.
If the unit continues to operate abnormally, please contact our peripheral device customer support center at
_____.
Problem
Check and remedy
UPS does not operate.
The LED display does not
light up, even though the AC
input plug is connected to a
wall outlet (commercial
power) and the power switch
is ON.
1. Check that the AC Input Plug is connected to the commercial power securely.
2. The AC Input Overcurrent Protection is working.
(If the black button has popped up, there are probably too many connected devices or
there is a short in the connected devices.) Disconnect all of the connected devices,
push in the the black AC input overcurrent protection button and turn ON the Power
Switch of the UPS again. If the status indicator does not display normally, there is a
problem with the UPS. (See "Interpreting beeps and displays" on page 39.)
Backup is not possible.
The computer stops when a
power failure occurs.
Is charging insufficient?
Perform the test after charging the battery for at least 8 hours. (When an additional battery
is connected, the charging time is 24 hours.)
(You can charge the battery by connecting the AC input plug of the UPS to a wall outlet
(commercial power).)
Backup is performed too
frequently.
Variations (decrease) in the input power occur frequently. Or, noise is included that
significantly distorts the voltage waveform of the input power.
Frequent switching is
performed although a power
failure does not occur.
You hear the sound of
switching.
●Change the wall outlet (commercial power) to which you connect the UPS. Try connecting
to a wall outlet (commercial power) away from equipment that consumes large power.
●This problem may occur also when you connect many devices to a plug strip or extension
cord connected to the UPS if it is a long or thin cable.
Does not turn ON when
power switch is pressed.
The unit does not start up when the input power supply voltage/frequency is abnormal.
(The status indicator displays “H-”, “-H”, “L-” or “-L”.) Check the voltage and frequency of
the input power supply.

A. Specifications Input Allowable voltage range, frequency see Page 88
The display is abnormal.
● The display is unstable.
● White lines occur.
The probable cause is noise that occurs inside the UPS.
●Ground all devices connected to the UPS. Connect them to a wall outlet (commercial
power) for 3-pin plugs or connect their Grounding Terminal to the Grounding Terminal of
a wall outlet.
● Noise increases.
●This problem may occur when power cords are long or placed closely or when the UPS
and devices to be backed up are placed closely. Rearrange them.
●If the UPS or devices connected to the UPS are contained in a metal rack, attempt to
ground the rack itself.
The battery replacement
lamp blinks and the beeper
sounds at 2-second
intervals.
1) The auto battery test or self-diagnostic test determined that the battery is dead.
2) Did the overcurrent protection switch on the rear panel of the additional battery unit get
turned OFF when connecting an additional battery unit?
If it is not ON, the auto battery test may falsely detect a deteriorated battery.
The status indicator shows
There are too many connected devices. Reduce the number of connected devices until
“
”, and the beeper sounds
“
” is displayed on the status indicator.
at 0.5-second intervals.
The status indicator blinks
The UPS stopped because too many devices were connected for 3 minutes or more, or
because 120% was exceeded.
Turn OFF all power to the unit and connected devices, and reduce the number of connected
devices. Then, turn the power to the unit and connected devices back ON and check
whether " " is displayed on the status indicator.
