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.

Notes on the use of the Backup Power Supply

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

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.

●

or less.

Page 13

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.

●

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

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.

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.

How to measure backup 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/Vista/XP/Me/2000/Windows NT/Linux:

●

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 disconnect-

ed.

Measuring the backup time

* The backup time you measure for the ﬁ rst 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).

Example 1) 100 VAC, 50/60Hz, 145 W

Example 2) 100 VAC, 50/60Hz, 1.8 A

Example 3) 100 VAC, 50/60Hz, 150 VA

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.

(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.

6-1

Checking the battery

The sealed lead battery used in the unit has a limited life. (The life varies depending on your storage/use environment and backup frequency.) The nearer the end of the life is, the more rapidly deterioration proceeds.

1. Life of battery (estimated replacement timing)

Ambient temperature

20°C

30°C

2. Methods for checking the battery

There are 3 methods for checking the battery.

• Perform a self-diagnostic test. (See page 24.)

• Use the auto battery test function. (See page 24.)

• Measure the backup time. (See page 29.)

By measuring the backup time, the battery life can be determined more accurately.

See also

If the measured value is equal to the "initial value of the backup time" or less than half the value ob-

tained from the graph of "Estimated backup time" on page 29, replace the battery.

• When you compare the "initial value of the backup time" you measured and the current backup

Replacing the battery

The battery can be replaced either while the unit is stopped (power supply output stopped) or while it is in operation (outputting power supply).

Caution

When the unit is used in compliance with UL standards or CE marking, do not replace the battery while in operation (while power is being output). Replacing the battery while in operation does not comply with UL standards or CE marking. Make sure to stop the operation of the unit before replacing the battery.

* When replacing the battery, stop the connected devices, turn OFF the power switch of the UPS, and

disconnect the AC input plug from the wall.

* If an input power supply error such as a power failure occurs when replacing the battery while in opera-

tion, backup cannot be performed and output stops.

* Do not replace the battery during backup operation. Output will stop.

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 32.

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 ﬁ les 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.

Contact signal

Contact Signal

You can develop your unique system based on the following speciﬁ cations 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 battery low signal. Also, by inputting the backup stop signal from the system, you can stop the UPS with a sufﬁ cient 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).

Backup Signal output: BU

●

BU stays ON during a power failure.

Battery Low Signal output: BL

●

Goes ON when the battery becomes weak during

the Battery Mode.

Trouble Signal output: TR

●

Goes ON when an internal failure of the UPS occurs.

Battery Replacement Signal output (WB)

●

Goes ON when the battery needs to be replaced

due to deterioration.

BU-COM ON when a power failure occurs

BL-COM ON when the battery is low

TR-COM ON when a power failure occurs

WB-COM

2. Input of the UPS Stop Signal (BS)

Stops the output of the UPS after the time period

speciﬁ ed 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 sec-

onds 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.

Extending the backup time

Connecting an additional battery unit

(BU100SW/

9-1

BU150SW only)

You can extend the backup time by connecting an additional optional battery unit to the UPS.

You can connect only one additional battery unit.

The explanation below is for connecting a BUM100S (for adding to BU100SW). Use these instructions when adding a BUM150S to a BU150SW. Some of the speciﬁ cations are different.

When an additional battery unit is connected, the charging time is 24 hours.

For the BUM100S, the included battery connection cable is provided with cable clamps attached. Connect the battery connection cable according to the instructions below. Cable clamps are not provided with the BUM150S.

(1) Loosen the screws and remove the battery connector covers on the rear side of the unit and battery unit.

Use the removed screws to attach the cable clamps.

(2) Connect the battery connection cable to the battery connectors on the rear side of the unit and the bat-

tery unit. To simplify the operation, do not yet tighten the screws that hold the battery connection cable on the cable clamp.

(3) Use screws to attach the cable clamps to the rear side of the unit and the battery unit (2 screws each).

(4) Tighten the screws that hold the battery connection cable on the cable clamps.

(5) Turn ON the overcurrent protection switch on the back of the battery unit.

(6) Connect the AC input plug of the unit to a wall outlet. The additional battery lamp on the unit's operation

panel turns ON.

Troubleshooting

Perform the checks shown below if the unit is operating abnormally. If the unit continues to operate abnormally, please contact our Electronic System & Eqiuipment customer support center at _____.

Problem

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.

Backup is not possible. The computer stops when a power failure occurs.

Backup is performed too frequently. Frequent switching is performed although a power failure does not occur. You hear the sound of switching.

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 de-

vices 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 20.)

Is charging insufﬁ cient? Perform the test after charging the battery for at least 8 hours. (You can charge the battery by connecting the AC input plug of the UPS to a wall outlet (commercial power).)

Variations (decrease) in the input power occur frequently. Or, noise is included that signiﬁ cantly distorts the voltage waveform of the input power.

Change the wall outlet (commercial power) to which you connect the UPS. Try con-

●

necting 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 ex-

●

tension cord connected to the UPS if it is a long or thin cable.

Check and remedy

The display is abnormal.

The display is unstable.

●

White lines occur.

●

Noise increases.

●

The battery replacement lamp blinks and the beeper sounds at 2-second intervals.

The status indicator shows “ ”, and the beeper sounds at

0.5-second intervals.

The status indicator blinks “ ”, and the beeper sounds con-

tinuously.

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. 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 auto battery test or self-diagnostic test determined that the battery is dead. Battery Mode cannot be performed, so the battery pack needs to be replaced.

There are too many connected devices. Reduce the number of connected devices until “

” is displayed on the status indicator.

Output stopped due to exceeded connection capacity. 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.
