As the peak current of a page printer is large, an excess of the connection capacity or a power failure due
to instantaneous voltage drop may be detected.
Do not use the unit for devices that malfunction due to an instantaneous power failure
of 10msec (0.01 second) or less.
The connected device may stop due to switching time of 10msec or less.
Do not use the unit for inductive devices such as fluorescent lamps.
Connected devices may stop due to a rectangular wave output.
Inductive devices include devices incorporating transformers, coils, motors, and so on for their input.
Do not fail to confirm the system operation beforehand if the unit is used combined
with devices which power supply frequency fluctuate widely, such as private electric
generator.
This 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 commercial power supply to another power supply
source, such as generating equipment, will cause no problem.)
Do not fail to confirm the system operation beforehand if the unit is used
other than “Output 100V mode”. (for BX50FW/BX75SW only)
At the time of battery operation, the maximum voltage (peak voltage) of output (rectangular
wave) may be lower than the maximum voltage at the time of usual operation (commercial
power supply). For this reason, some connected devices may fail to operate normally.

failure of 10msec (0.01 second) or less.
● The connected device may stop due to the switching time of 10msec or less.
Do not use the unit for inductive devices such as fluorescent lamps.
● Connected devices may stop due to a rectangular wave output.
● Inductive devices include devices incorporating transformers, coils, motors, and so on for their input.
Do not fail to confirm the system operation beforehand if the unit is used combined
with devices which power supply frequency fluctuate widely, such as private electric
generator.
● This 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 commercial power supply to another power supply source, such as
generating equipment, will cause no problem.)
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 250 VDC 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.
Do not fail to confirm the system operation beforehand if the unit is used other than
"Output 100V mode". (for BX50FW/BX75SW only)
● At the time of battery operation, the maximum voltage (peak voltage) of output (rectangular wave) may be
lower than the maximum voltage at the time of usual operation (commercial power supply). For this reason,
some connected devices may fail to operate normally.

6. Using the Contact Signal
6. Using the Contact Signal
(only for BX50FW, BX75SW)
You can develop your unique system based on the following specifications to automate the process at the
power failure.
Your can perform power-failure or closing procedure of the system by detecting the Backup Signal and the
Battery Low Signal, or receive failure notification by detecting the Trouble Signal.
You can stop the UPS by inputting the UPS Stop Signal from the system, and remote control start and stop of
the UPS by using the Remote ON/OFF Signal.
Also, this function is valid only when “connection communication” is selected for the “switching switch”. (See
item 2 on page 35.)
1. Signal output
The UPS has 5 kinds of output signals. The output circuit consists of an open collector circuit using a photo
coupler (a kind of electronic switch).
Backup Signal output: BU
Backup Signal reverse output: NBU
BU-COM ON when a power failure occurs
NBU-COM OFF when a power failure occurs
BU stays ON (NBU OFF) during a power failure.
NBU is output only when the”gcommunication connector 9th-pin output signal switching setting” (setting switch 8 ) is set to ON.
Battery Low Signal output: BL
BL-COM ON when the battery is low
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 battery needs to be replaced due
to deterioration.
WB is output only when the “communication connector 9th-pin output signal switching setting” (setting
switch 8 ) is set to OFF.
2. Input of the UPS Stop Signal (BS)
BS-COM UPS stops
Stops the output of the UPS after the time period specified by the “power output stop delay time setting” (setting switches 5 and 6 ) has elapsed.
(1) When the "UPS Stop Signal 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 "UPS Stop Signal 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.

7. Measuring the backup time (checking the discharge time of the battery)
7. Measuring the backup time
(Checking the discharge time of the battery)
7-1 Measuring method of the backup time
(1) Connect the AC Input Plug of the UPS to a wall outlet (commercial power) and charge it for approximately
12 hours.
If you operate the UPS for 12 hours or more, it is charged. If a power failure occurred during this period,
charge it again.
(2) Turn ON all devices connected to the power output to be “backed up during a power failure”.
(Including devices connected to the AC outlet of your computer.)
Operate them in a way in which it is allowable that power supply to the connected devices stops.
● For Windows Server 2003/XP/Me/2000/Windows NT/Linux:
To be performed in case of hard drive stops.
● For Windows 98/95:
Choose Shut Down of 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."
7-2 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) Unify the total capacity (power consumption) of connected devices to W (Watt).
For the indication of connected devices, check your computer and the rear of the display.
There are 3 types of indication: VA (Volt·Ampare) indication, A (Ampare) indication, and W indication.
Example 1)
100 VAC, 50/60Hz, 145 W
Indication
Value
Example 2)
100 VAC, 50/60Hz, 1.8 A
VA
× power factor = W
Example 3)
100 VAC, 50/60Hz, 150 VA
A
× power factor × 100 = 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.
- 47 -
7. Measuring the backup time (checking the discharge time of the battery)
(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 (initial value for product that has not been used)
● The smaller the capacity of connected devices becomes, the longer the backup time becomes.

8. Troubleshooting
8. Troubleshooting
Perform the checks shown below if the unit is operating abnormally.
If the unit continues to operate abnormally, please contact the shop of purchase.
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 worked and opened.
(If the black button is popped up, it is suspected that there are too many connected
devices or there is a short in connected devices.) Disconnect all of the connected
devices, push in the AC Input Overcurrent Protection Black 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 a beep and display" on page 29.)
3. Isn't the voltage of the wall outlet (commercial power) too low?
Stop devices that consume a lot of power such as an air conditioner. Check the UPS, for
example, by connect it to a wall outlet (commercial power) in another room or house.
(It does not operate when the voltage is less than 90V.)
Backup is not possible.
The computer stops when a
power failure occurs.
Isn't charging insufficient?
Perform the test after charging the battery for at least 12 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.
Frequent switching is
performed although a power
failure does not occur.
You hear the sound of
switching.
1. The input power supply may be at fault. Connect the UPS to a wall outlet (commercial
power) in another room or, if possible, another house and check it. Or, stop large devices
such as a cooler.
2. Isn't a page printer connected?
Because large current flows instantaneously in printers, normal backup is not possible.
The display is abnormal.
The display is unstable.
White lines occur.
Noise increases.
1. The UPS generates some noise when performing backup. For displays susceptible to
noise, distortion or white lines may occur, but the UPS is not at fault.
2. Grounding the UPS, computer, and display may improve this problem.
3. Noise during backup may become larger depending on connected devices, you can
continue to use the UPS because this occurs due to rectangular wave output.
The battery replacement
lamp blinks and the beeper
sounds at 2-second
intervals.
The battery is judged to be dead in the auto battery test or the self-diagnostic test.
Battery Mode cannot be performed and therefore replace the battery pack.
The status indicator shows
“ ”, and the beeper sounds
at 0.5-second intervals.
There are too many connected devices. There are too many connected devices. Reduce
the number of connected devices until “ ” is displayed on the status indicator.
The status indicator blinks
“ ”, and the beeper
sounds continuously.
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.
The output voltage is only
approximately 80 V when
measuring it with a tester.
The UPS outputs a special rectangular wave during the Batter Mode. Due to its
characteristics, simple testers indicates approximately 80 V. The UPS is not at fault. To
make correct measurement, you need a voltmeter that can measure "true rms value."

9-4 About the included UPS monitoring software
Using the included UPS monitoring software allows you to automatically save data files and shut down your
computer when a power failure occurs. However, make settings so that the time from the occurrence of the
power failure until computer shutdown is less than the maximum backup time. For more details, refer to the
instruction manual and online help for the UPS monitoring software.
Using the included UPS monitoring software also enables you to change the unit’s operation mode settings,
use additional functions, perform scheduling operations, etc.
Explanation
Starting operation during a scheduled stop with UPS monitoring software
● If the unit starts operation during a scheduled stop period, turn the power switch OFF once, and then
turn it back ON.
You can start the unit manually.
In this case, the next scheduled ON operation is cancelled.
Auto restart after OS shutdown by UPS monitoring software
● In the event of a power failure, some PC models (see *1 below) automatically restart immediately after
the completion of the OS shutdown processing by the UPS monitoring software.
In this case, the unit stops during restart or after startup, possibly damaging files and/or the hard disk.
This problem can be avoided by disabling POWER MANAGEMENT in the BIOS settings.
*1) PC models: This problem has been reported with MICRON Millenia Mme.
● When the PC does not start up automatically, select the “System startup at power restoration” setting
(example: “Restore On AC/Power Loss) in the BIOS settings of your PC, and change to a “System
startup after power restoration” setting (example: “Power On). Individual BIOS setting methods and/or
displays may differ depending on the PC. For more information, refer to your PC instruction manual or the
technical support center for your PC.
● When considering a system with automatic startup at power restoration, choose a PC that satisfies the
condition shown below. For more information on PC operation when input power is supplied, consult
your PC instruction manual or contact the PC technical support center.
<Condition>
Without pressing the power switch, the PC starts up when input power is supplied.
● After shutdown processing in the event of a power failure, the unit restarts automatically and supplies
power once power is restored.
If you do not want the devices connected to the UPS to start up, turn OFF their switches.
● The automatic restart setting can be disabled in the included UPS monitoring software.

This UPS outputs power input from commercial power as it is and charges the battery at the same time. If a
power failure or voltage variation occurs, the UPS automatically switches to operation using the battery and
continues power output. At this time, the beeper sounds intermittently. When the power is recovered, normal
operation using commercial power is automatically recovered. (The beeper stops.) You do not have to perform
any operation.
