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, and surge voltage such as that caused by lightning (a phenom-
enon in which extraordinary high voltage occurs instantaneously).
●The BN50S/BN75S/BN100S/BN150S/BN220S/BN300S are line interactive UPS with simple
output voltage adjustment functions. Under normal service conditions, commercial power
input passes through the transformer and is output, and when the input voltage is low, the
transformer raises the voltage, and when the input voltage becomes high, the transformer
lowers the voltage. In addition, when abnormalities in commercial power are detected, such
as in a power failure or when there are large changes in voltage, power supply is shifted to
the battery within 10ms, and sine wave output is continued.
●BN50S output capacity is 500VA/450W, BN75S output capacity is 750VA/680W, BN100S
output capacity is 1000VA/900W, BN150S output capacity is 1500VA/1350W, BN220S out-
put capacity is 2200VA/1980W and BN300S output capacity is 3000VA/2700W.

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.
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 com-
mercial 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.
Before performing a withstand voltage test or insulation resistance test, make
sure to remove the input surge protection GND screw from the back of the unit.
When in use, make sure the input surge protection GND screw is securely
fastened.
●Performing the withstand voltage test with the ground wire connected may damage the surge absorption
element built into the power supply input circuit.
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.

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 recom-
mend 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 30
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 42.
The cooling fan operation of BN100S/BN150S/BN220S/BN300S
●The cooling fan starts operating at the Battery Mode due to a power failure, auto battery test, self-diag-
nostic test, etc., and automatically stops after a period of approximately 24 hours when the UPS returns
to the Commercial Power Mode and the battery is fully charged.
Pb
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.
Notes
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.

Two or more people should work together to carry, unpack and install the
unit (BN100S/BN150S/BN220S/BN300S).
●Because the unit is heavy, you may injure yourself or drop the unit, or it may fall over.
Carry the unit considering its weight and balance, and place it on a stable
and robust base.
●Dropping or toppling the unit may cause injury.
●Approximate weight of the unit:
10kg (BN50S/BN75S) 22kg (BN100S/BN150S) 38kg (BN220S/BN300S)
●If you drop the unit, stop using it and have it inspected and repaired.
For repair, contact us; ____
Keep plastic package bags out of reach of children.
●Children may suffocate if they place their heads into plastic bags.
Make sure to connect the unit’s AC input plug to a commercial power
source with rated input voltage (100 to 115V AC) and 50/60Hz frequency.
●Connecting to a wall outlet (commercial power) with a different voltage or frequency may result
in a fire.
●The unit may fail.
When an abnormality (unusual sound or smell) occurs, turn OFF the unit's
power switch and disconnect the AC input plug from the wall outlet.
Install the unit soon after the AC input plug is disconnected from the
wall outlet.
●When performing maintenance on the connected devices, follow the above instructions to en-
sure safety.
Do not connect devices such as dryers, some solenoid valves, etc. ,
which have a half-wave rectifier that allows only half-cycle AC power to
flow through.
●Overcurrent may damage the UPS.
Connect the unit to a wall outlet (commercial power) with a capacity of
7A (BN50S) / 10A (BN75S) / 15A (BN100S) / 20A (BN150S) / 30A (BN220S) /
42A (BN300S) or more.
●Otherwise, the power cord may be heated.
●
When equipment with the maximum output capacity is connected, a maximum current of XXA
(BN50S) / 10A (BN75S) / 15A (BN100S) / 20A (BN150S) / 30A (BN220S) / 42A (BN300S) / flows.
Provide secure grounding.
●After checking the plug shape of the wall outlet, directly connect the AC input plug of the unit
to it. A failure or leak that occurs when the unit is not properly grounded may result in electric
shock.
Do not disassemble, repair, or modify the unit.
●Doing so may cause an electric shock or a fire.
Do not install the unit in other than specified orientations.
●Dropping or toppling the unit may cause injury.
●If you install the unit in an orientation other than specified, the unit cannot be protected from a
battery fluid leakage.

Do not use the unit where the maximum temperature exceeds 40°C.
●The battery becomes weak rapidly, which may cause a fire.
●Doing so may cause a failure or malfunction of the unit.
Do not exceed the ranges specified for environmental conditions during
use/storage.
Do not install or store the unit in the places listed below.
●Do not store in places where the humidity is lower than 10% or higher than 90%.
●Do not use the unit in places where the ambient temperature is lower than 0°C or higher than
40°C.
●Do not use in places where the humidity is lower than 25% or higher than 85%.
●Do not install/store the unit in closed places such as cabinets with no clearance, places where there
is flammable or corrosive gas, places exposed to direct sunlight, places with large amounts of dust,
places exposed to shock or vibration, or outdoors.
●Installation or storing the unit in such a place may cause a fire.
Do not connect equipment that exceeds the output capacity of the unit.
You can use a plug strip to connect additional devices, but do not connect
devices that exceed the current capacity of the plug strip.
●The current protection of the unit may operate, which may stop the output.
●The wiring of the plug strip heats up, which may cause a fire.
Do not pinch or tie the cable of the unit.
●
Doing so may cause the cable to be damaged or heated, which may cause an electric shock or a fire.
●If the cable is damaged, stop using the unit and have the cable repaired.
For repair, contact us; ____
Do not use any of the included accessories with other devices.
●The accessories are designed exclusively for use with this unit.
●Doing so may compromise the safety of devices.
Do not block the air vents on the front and back of the unit (the BN50XS/
BN75XS has air vents on the sides).
●Doing so will cause the internal temperature to rise, which may cause the unit to fail and the bat-
tery to deteriorate.
●Leave at least 5 cm of space between the vent and the wall.
Do not connect a transformer such as a voltage transformer or isolating
transformer to the output side.
●Overcurrent may damage the UPS.
●Even when connected to the input side, the UPS may fail or malfunction. Make sure to check the
operation before use.
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, by-
pass operation is performed and commercial power supply is supplied as is to the connected
devices.
