Features of this product
Thank you for purchasing Omron's Uninterruptible Power Supply (UPS).
●The UPS protects computers and other devices from power failures, voltage variations, in-
stantaneous voltage drops/power failures, and surge voltage caused by thunders and so on
(a phenomenon in which extraordinary high voltage occurs instantaneously).
●Under normal conditions, it converts the commercial power to a direct current once, recon-
verts it to a stable 100-VAC sine wave, and outputs it.
When detecting a failure of the commercial power, it switches to battery-supplying to provide
the continuous output of a sine wave. This is called On-line Power Method.
It is suitable especially for use where power supply conditions are bad (for example, voltage
variations are large).
●The output capacity is 500VA/350W for BU50XS, 700VA/490W for BU70XS and 1KVA/700W
for BU100XS.
●It provides Network line surge protection function to protect communication devices such as
modems from surge voltage that comes through the line (a phenomenon in which extraordi-
nary high voltage occurs instantaneously).

Safety precautions
Notes
Charge the battery (for at least 8 hours) immediately after purchasing the product.
●If you do not use the product for a long time after purchase, the characteristics of the battery may deteriorate
and become unavailable.
●When you connect the AC Input Plug of the UPS to a wall outlet (commercial power), the battery is automati-
cally charged.
If you store the UPS, charge the battery for at least 8 hours before storage.
●Even if you do not use the battery, it discharges spontaneously and goes into over discharge status if it is left
for a log time. The backup time may become shorter or the battery may become unavailable.
●The storable period of the built-in battery of the UPS is 6 months after charging it for at least 8 hours.
●If you want to store the battery longer than 6 months, connect the AC Input Plug of the UPS to a wall outlet for
at least 8 hours before the limit is exceeded.
●Press the Stop Switch of the UPS to stop it during storage.
Do not reverse the connection of Line/Hub Side and Modem/TA/PC Side of the Network
Line Surge Protection.
●If a failure of the protection circuit occurs, the line side (telephone/ISDN line) may be damaged.
Do not short the output lines of the UPS each other and the output lines to the ground.
●The UPS may fail.
Do not connect the AC Input Plug of the UPS to its Power Supply Output Receptacle.
●The UPS may fail.
Before cutting out commercial power by turning off the breaker or disconnecting the
AC Input Plug, stop the UPS.
If you cannot stop 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 charging 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 less the effect on the lift becomes.
Do not connect a page printer to the UPS.
●The connection capacity may be exceeded repeatedly during operation using commercial power, which
may cause the status in which the input voltage is outputted directly (bypass mode).
●The peak current of the page printer is large and it may be detected that the connection capacity is ex-
ceeded.
Do not perform a withstand voltage test.
●The input circuit of UPS 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.

Safety precautions
Explanation
Usual operation
●You may continue the operation of the UPS or stop it each time shutting down the connected
system.
You can choose either of the operation methods for your convenience.
●Connecting the UPS to a wall outlet (commercial power) charges the battery.
End of Battery mode
●If the time of a power failure is long, the voltage supply from the UPS stops. Shut down you computer using
a proper procedure (for example, saving data) while the UPS supplies the voltage.
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 supplies the voltage. If
you do not want to start the connected equipment, turn off its power switch.
●The UPS monitoring software allows you to disable automatic restart.
Scheduled operation using the UPS monitoring software
●When performing scheduled operation in which the UPS is stopped and the commercial power is stopped
using a breaker and so on at the same time, specify a period within 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 opera-
tion does not start.
Notice that this period reduces to approximately half when the battery is dead.
If 3 months are exceeded, you start operation by supplying commercial power and press 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 29.
Notes
Recycling and Discarding the Battery
●The UPS uses a lead acid battery. It is recyclable, precious resources. Please recycle it when
you replace it or discard the produce you do not use any more.
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 unavailable.

2-3 Connecting the equipment
(1) Disconnect the AC Input Plugs of all devices you want to back
up such as your PC and modems from a wall outlet (commer-
cial power).
(2) Connect devices you want to back up to the Power Supply
Output Receptacles of the UPS.
•If you need more output receptacles than those of the UPS,
purchase a plug strip and so on separately and use it as
extra output receptacles.
•Even if the input plug of a device you want to connect is 2-pin type, you can connect it directly to the
Power Supply Output Receptacle of the UPS. Notice that the input plug is 2-pin type with the grounding
wire, connect the grounding wire to the Grounding Terminal of the UPS.
•When you want to use an AC adaptor, connect it to a Power Supply Output Receptacle of the UPS with
space enough for the connection.

2. Installation and connection
●The UPS 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 the UPS before using it.
When you connect the AC Input Plug of the UPS to a wall outlet (commercial power), charging the
battery is automatically started and it is fully charged for 8 hours or less.
●You can perform "2-4 Checking the operation" on page 17 also before charging the battery.
(3) Connect between the UPS and the surge protection circuit.
See also "7. Using the Network Line Surge Protection Function" on page 35
* If you do not use the Network Line Surge Protection Function, this step is not required.
(4) If you use the attached UPS monitoring software or the standard UPS service of Windows NT or Windows
XP/2000 or if you use Contact Signal, connect the connecting cable between the UPS and your PC.
See also "8. Using the UPS monitoring software and Contact Signal" on page 36
* If you do not use the UPS monitoring software and Contact Signal, this step is not required.
(5) When the installation and connection is complete, connect the AC Input Plug of the UPS to a wall outlet
(commercial power).

2. Installation and connection
2-4 Checking the operation
Before use, check that the Battery mode is performed normally according to the following procedure.
This operation check simulates an occurrence of a power failure by disconnecting the AC Input Plug from a
wall outlet.)
Caution
If the input plug is disconnected while the product is operating, never touch its
metal part.
●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) Connect your PC and other devices to the UPS and then connect the AC Input Plug of the UPS to a wall
outlet (commercial power).
(2) Press the Start Switch to start the operation of the UPS.
Bring all connected devices into operation at the start of the operation.
(Including devices connected to the AC outlet of your PC.)
Operate them in a way in which it is allowable that power supply to the connected devices stops.
(3) Under this condition, check the display lamps of the UPS.
Are they the same status in the right figure?
Yes
The operation is normal.
Proceed to (4).
No
The operation is abnormal.
The display is one of them described in "C. Failure
(display and beep when a failure occurs in equipment)"
on page 23. Take necessary measures according to
the remedy and then proceed to (4).
