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, in-

stantaneous voltage drops, and surge voltage such as that caused by lightning (a phenom­enon in which extraordinary high voltage occurs instantaneously).

●

Under normal conditions, a stable sine wave AC voltage is output by raising the voltage (when

the input voltage is low) or lowering the voltage (when the input voltage is high) according
to the input voltage status, in synchronization with commercial power input. In addition, a
full-time inverter supply method (high efciency) is employed; when abnormalities in com­mercial power are detected, such as in a power failure or when there are large changes in
voltage, power supply is uninterruptedly shifted to the battery, and sine wave output is con­tinued.

●

Output capacity is 2000VA/1400W for BU2002RWL, 3000VA/2100W for BU3002RWL and

5000VA/3500W for BU5002RWL.

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 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.

●

The battery can be charged once the AC input plug is connected to commercial power.

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

●

The battery self-discharges even when it not being used, and it goes into over-discharge state if it is left

for a long period of time. 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.

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 terminal of the unit to its Power Supply Output
terminal 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.

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 withstand voltage tests.

●

Performing withstand voltage tests may damage the surge absorption element built into the power supply

input circuit.

●

When performing an insulation resistance test, use the 400 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 signicantly shortened.

If this unit is used for 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.

xi

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 unit is connected to a commercial power source.

Quitting Battery Mode

●



If a power failure lasts for an extended period of time, the battery discharges completely 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 output stops. After recovery from the

power failure, the unit automatically restarts and output begins. If you do not want to restart the connected
devices, disable the “Settings” - “Boot Settings” - “Auto reboot” setting in the menu on the unit’s LCD, or
turn OFF the power switch of 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 needs to be replaced. If a
period of 3 months is exceeded, you start operation by supplying commercial power and pressing the start
switch. However, if the battery needs to be replaced, you may not be able to start operation.

In this case, replace the battery

.

Pb

Notes

Check system operation beforehand if the unit is used in combination with a

device whose power supply voltage and frequency uctuate widely, such as a

generator.

●

If the generator’s output voltage/frequency falls out of the input voltage/frequency range, the unit will enter

Battery Mode.

●

Even if the input frequency is within the range, the unit will enter Battery Mode when a rapid change (5

Hz/sec or greater) occurs.

In the event you transfer or sell this unit to a third party, please include all of the
documentation that came with the unit. This is to ensure that the unit is used in
line with the conditions described in the included documentation.

2.Installation and connection

23

The battery automatically starts charging when the unit is connected to a commercial power

source.
(This occurs regardless of whether the power switch is ON or OFF.)
The charging takes 8 hours to complete.

●

The unit was charged before shipment, but it may have self-discharged during shipment, resulting

in a reduced backup time. We recommend charging the unit before use.

●

If you do not perform the initial backup time measurement described below in “2-7 Measuring the

initial value of backup time”, proceed to “3. Operation. → Page 24”

●

When you measure the backup time initial value of the unit in your environment, this value can

be used as a guide when checking the battery and deciding the UPS monitoring software setting
values.

See also

"5. Measuring the backup time" → Page 34

The battery is discharged completely when the backup time is measured, so you need to recharge it
before using the UPS.

●

You can use connected devices while recharging the battery, but the backup time when a power

failure occurs is shorter until the battery is fully charged.

(If a power failure occurs immediately after the start of charging, backup stops immediately.)

3.Operation

25

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 is connected to 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, disable the “Settings” - “Boot Settings” - “Auto reboot” setting in the menu on the unit’s LCD, or turn
OFF the power switch of 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 less than half when the battery needs to be replaced.
If a period of 3 months is exceeded, you start operation by supplying commercial power and pressing the

Start

Switch. However, if the battery needs to be replaced, you may not be able to start operation. In this

case, replace the battery.

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 signicantly shortened.

Take measures for handling unforeseen accidents, such as data backup
and system redundancy.

●

This test performs a failure diagnosis on the unit and performs a test to check for battery deterioration.

Use the procedure below to check whether a circuit failure has occurred inside the unit and whether
battery replacement is required.

This test is performed if the “Power” switch is ON or performed automatically (You do not have to
perform any special operations). Automatic test is performed once every 4 weeks after the unit is con­nected to a commercial power source and power distribution begins.

If the battery is not charged for at least 24 hours, the self-diagnostic test is not executed immediately.

After charging is complete, it is automatically executed.

(1) When the self-diagnostic test is executed, the Battery Mode starts automatically (No beep

sounds). After the test is complete, the normal operation automatically starts.

(2) If an error message appears on the LCD:
Follow the directions for the solutions described earlier in this document.

* This test can also be run from the included UPS monitoring software.
For more details, refer to the online help for the UPS monitoring software.

When the beep is sounding, you can suspend it by pressing and
holding the beep ESC switch for 0.5 seconds or longer.

(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) 200 VAC, 50/60Hz, 145 W

Example 2) 200 VAC, 50/60Hz, 1.8 A

Example 3) 200 VAC, 50/60Hz, 150 VA

For devices that use the VA or A indication, convert the capacity into W. Multiply the value indi-

cated 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 at 25°C)

The backup time becomes shorter than the graph (table) below when temperature is lower.

●

The smaller the capacity of connected devices becomes, the longer the backup time becomes.

(1) Connect to commercial power and charge the battery for 8 hours (Charging time is extended 24

hours per unit, if additional battery unit is connected).

(2) Turn ON all devices connected to the unit.

(3) Turn off the commercial power and measure the backup time.

In Battery Mode, measure the time until the unit automatically stops and all displays disappear.

The power supply output of the unit will stop when the battery discharges. Conduct
measurement under a condition in which no problem occurs even if the power supply of the
connected device stops during the process. Do not conduct measurement if there is a
possibility of a failure when the power supply stops.

The lead battery used in the unit has a limited lifespan.
(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. Battery life expectancy (* Not a guaranteed performance)

2. Methods for checking the battery

There are two methods for checking the battery.

• Perform a self-diagnostic test. (See page 30.)

• Measure the backup time. (See page 34.)

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

• When you compare the "initial value of the backup time" you measured and the current
backup time, make the capacity of devices connected to the UPS same as when you mea­sured the initial value to make judgment accurately.

When maintaining the connected equipment, turn OFF the unit’s power
switch to stop the output, and stop the supply of commercial power.

●

Even if commercial power to the UPS is stopped while it is in operation, the power output of this

unit does not stop and power is supplied from the receptacle.

Do not disassemble, repair, or modify the unit.

●

Doing so may cause an electric shock or a re.

If uid leaks from the unit, do not touch the uid.

●

Doing so may cause blindness or burns.

●

If the uid contacts your eyes or skin, wash it out with lots of clean water and consult your doctor.

Do not throw the unit into re.

●

The lead battery in the unit may explode, or leak dilute sulfuric acid.

Do not insert metal objects into the power supply output receptacles of the UPS.

●

Doing so may result in electric shock.

Do not insert metal objects into the battery connectors.
Do not create a short between the connector terminals.

●

Doing so may cause an electric shock.

• UPS monitoring software function list

*1) The UPS automatically stops only when the battery is depleted. (Battery Mode continues until the battery is depleted.)
*2) Only the battery capacity can be monitored.
*3) This function is available only for Windows, not for Linux.
*4) BU5002RWL comes equipped with SC20G.

[Explanation of software functions]

1 Auto shutdown The computer can be shut down automatically when a problem occurs with the power supply.

2 UPS monitoring (operating

status)

The operating status of the UPS can be monitored (in Commercial Power Mode/Battery Mode).

3 UPS monitoring (data) Monitoring can be performed for input voltage value, connection capacity, battery capacity, etc.

4 Pop-up notication When a problem such as a power failure occurs, a pop-up window that shows the details of the problem can be displayed.

5 Shutdown when OS is

inactive

Shutdown can be performed when the computer is in an inactive state. The operating status is retained at shutdown in inactive
state, so operation details are not lost.

6 Schedule operation Schedule settings can be made for UPS stop/start.

7 UPS setting change UPS settings (beep ON/OFF, etc.) can be changed. (Items that can be set vary according to the UPS.)

8 External command

execution

By executing commands at shutdown, items such as application programs can be launched.

9 Event log save Information of events that occur on the UPS (power supply problems, setting changes, occurrences of failure, etc.) are saved as

a log.

10 Data log save Data of input/output voltage value, connection capacity, etc. is periodically saved as a log (the save frequency can be set).

11 Coordinated shutdown When a problem occurs with the power supply, multiple computers connected to the UPS can coordinate to perform auto

shutdown.

12 Output receptacle control The UPS output receptacles can be individually set to ON/OFF.

13 Redundant power supply

support

Two or more UPS can be connected to computers equipped with redundant power supply. Shutdown is not performed when a
power supply proble affects only one of the units. Shutdown is performed only when a power supply problem occurs with both
UPS, so the system's operating rate is improved.

14 Remote UPS management The UPS can be managed remotely from a computer on the network.

15 Mail send When a problem such as a power failure occurs, a notification email describing the problem can be sent to the system

administrator.

16 SNMP management UPS management information can be sent to the SNMP manager.

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 needs to be replaced.
If a period of 3 months is exceeded, you start operation by supplying commercial power and pressing

the

Start Switch. However, if the battery needs to be replaced, you may not be able to start operation.

In this case, replace the battery.

Start of operation in scheduled operation using the UPS monitoring software

●

T

o 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.

T

o 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 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.

Precautions when “setting the UPS to stop automatically” after OS shutdown

●

If,

after a power failure occurs, the power is restored while auto shutdown processing is being per-

formed, UPS output stops once after the set time elapses. After shutdown processing is complete, do

not turn ON the computer until the UPS has nished restarting.

2003/XP

When using the product with the optional BUC26 cable, the OS standard UPS service in Windows
Server 2003/XP can be used. When there is a power failure, the computer can be shut down.

1. Connect the UPS to a computer.

* Only 1 computer can be connected to the UPS

Connection cable (BUC26), sold separately (Connect to contact signal port)

2. Perform UPS service setup.

You need to make Windows settings in order to perform auto shutdown. There is no need to install
software.

7. Using the UPS monitoring software and contact signal

43

Contact signals are included as standard for the unit.

Contact Signal

You can develop your unique system based on the following speci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
Low battery level signal. Also, by inputting the backup stop signal from the system, you can stop the

UPS with a sufcient battery level to prepare for the next occurrence of a power failure.

7-4-1. 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

Stays ON during backup operation at a power

failure.

●

Low battery level signal output: BL

Goes ON when the battery becomes weak

during backup operation at a power failure.

●

Trouble Signal output: TR

Goes ON when a failure of the UPS occurs or

when the battery life counter
expires.

●

Battery Replacement Signal output (WB)

Goes ON when the test determines that bat-

tery replacement is necessary due to deterio­ration or when the battery life counter goes
off-scale.

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

ON when replacing the battery

7-4-2. Signal input

●

Input of the UPS Stop Signal (BS)

When the BS signal is ON (High), the output of the UPS is stopped after the time period specied

in advance has elapsed. The following settings are available on the LCD.

(1) BS Valid Range: "Settings" - "Dry Contact" - "BS Valid Range"

• Always enabled : The BS signal is received either in Commercial Power Mode
or Battery Mode.

• Enabled during Battery Mode: The BS signal is received only in Battery Mode.

(2) BS Delay Time: "Settings" - "Dry Contact" - "BS Delay Time"

You can set the amount of time between when the BS signal is received and when the output

of the UPS is stopped.

BS-COM UPS stops

7-4

Contact signal

●

Remote ON/OFF Signal

Remote ON/OFF signals can be used to start

and stop the UPS, by using either an externally
connected contact or the ON/OFF status of the
open collector circuit.

Problem Check and remedy

The LCD does not appear when
the UPS is connected to com­mercial power and the power
switch is turned ON.

1.

Make sure the

AC input is securely connected to commercial power.

2.

AC

input overcurrent protection is activated and power is cut. (For BU2002R

­WL and BU3002RWL, the black button has popped up. For BU5002RWL, it
is tilted towards OFF.)

•

If the black INPUT

PROTECTION button pops up, there are too many con

-

nected devices or there was a short-circuit with the connected devices.
D

isconnect all the connected devices, press the black INPUT PROTEC-

TION switch (overcurrent protection switch), and turn on the power switch.

•

If the status indicator does not display properly after you perform the above

operation, there is a problem with the unit.

(See “3-3 Interpreting beeps and displays” on page 29.)

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

The battery may not be fully charged.
Perform the test after charging the battery for at least 8 hours.
The battery can be charged just by connecting to a wall outlet. The “Power”
switch can be either ON or OFF.

Backup is performed too fre

­quently.
Frequent switching is performed
although a power failure does
not occur

.

You hear the sound of switching.

Variations (decrease) in the input power occur frequently. Or, noise may be in

-

cluded that signicantly distorts the voltage waveform of the input power.

●

Try and check what happens when connecting the unit to a different wall out-

let (commercial power) located some distance away from the device consum­ing a large amount of power.

●

This problem may occur also when you connect many devices to a plug strip

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

Does not turn ON when power
switch is pressed.

The unit does not start up when the input power supply voltage/frequency is
abnormal. (“AC I/P abnormal” is displayed on the LCD.) Check the voltage and
frequency of the input power supply.

See also

A. Specications Input voltage range, Input frequency see Page 66

The display is abnormal.

●

The display is unstable.

●

White lines occur.

●

Noise increases.

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, at-

tempt to ground the rack itself.

The battery replacement lamp
lights up or blinks, and the beep­er sounds at 2-second intervals.

●

When the battery replacement lamp blinks: Judged as battery deterioration

by self-diagnosis test. Replace the battery as only the short backup operation
time is available.

See also

4-2 Self-diagnosis test → page 30

●

When the battery replacement lamp is ON: Battery life counter went off-scale.

The life of the battery has expired. Replace the battery.

See also

4-3 Battery life counter function → page 31

“Overload” is displayed. There are too many connected devices. Reduce the number of connected de-

vices until the error is resolved.

“O

ver load time out” is displayed. 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 the error is resolved.
