Introduction

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,

●

instantaneous voltage drops, and surge voltage such as that caused by lightning (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 AC sine wave, and outputs it.

When a commercial power failure is detected, the unit switches to battery supply to

provide continuous sine wave output. This is especially suitable for use where power
supply conditions are poor (for example, when there are large variations in voltage).
The output capacity is 500VA/350W for BU50SW, 750VA/500W for BU75SW, 1000VA/700W

●

for BU100SW and 1500VA/1050W for BU150SW.

viii

BU50SW / BU75SW / BU100SW / BU150SW

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.
Recharge the battery for at least 8 hours every 6 months when the storage tempareture is
25

C

or less, or every 2 months when the storage temperture is 40

°

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.

●

Turn OFF the unit’s power switch when storing it.

●

Before storing an additional battery, charge it for at least 24 hours.

●

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
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 250V DC range.

●

Safety precautions

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 signifi cantly shortened.

Check the operation beforehand if the unit is used in any mode other than “Output
100V 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.

●

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.

●

This unit uses lead acid batteries,

Which are a valuable recyclable resource. Please recycle.

●

Pb

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.

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 32.

Setting switch 2 can be used to select whether or not auto restart is performed.

●

ceptacle may result in shock hazard as well as violate local electical codes.

Do not allow liquids or any foreign object to enter the UPS. DO not place beverages or any

●

other liquid-containing vessels on or near the unit.

This unit intended for installation in a controlled environment (temperature controlled, indoor

●

area free of conductive contaminants).Avoid installing the UPS in locations where there is
standing or running water,or excessive humidity.

Do not attach a power strip or surge suppressor to the UPS.

●

Do not attach non-computer-related items,such as medical equipment, life-support

●

equipment,microwave ovens,or vacuum cleaners to UPS.

With the installation of the equipment it should be prevented, that the sum of the leakage

●

current of the UPS and the connected consumer does not exceed 3.5mA.

Do not block the air vents on the side and rear of the unit.

BU50SW / BU75SW / BU100SW / BU150SW

Caution

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
connected devices.

When a 15A plug (NEMA5-15P) is used with BU150SW, the maximum
capacity connectable to output is approximately 1100VA/950W.

Doing so will cause the internal temperature to rise, which may cause the unit to fail and the

●

battery to deteriorate.

When the “15A input exceeded” display appears ( or is displayed on the status indi-

●

cator), replace the input plug with a 20A input plug.

When replacing the input plug for the BU150SW, perform connection
as specifi ed, making sure to properly match the plug terminals with the
appropriate wire colors.

Refer to “Using a 20A plug” on page 11.

●

Failure to do so may result in electric shock or ground fault.

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.
Recharge the battery for at least 8 hours every 6 months when the storage
tempareture is 25°C or less, or every 2 months when the storage temperture is 40°C
or less.

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.

●

Before storing an additional battery, charge it for at least 24 hours.

2. Installation and Connection

Notes

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 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 250VDC 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 signifi cantly shortened.

Check the operation beforehand if the unit is used in any mode other than “Output
100V 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.
