Preparation for operation 3. Preparation for operation 3-1 Charging the battery When you connect the AC input plug of this unit to a wall outlet (commercial power), the battery charg- ing automatically starts regardless of the on/off state of the Power Switch, and it is fully charged within 12 hours. This unit 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 this unit before using it. If you do not perform the initial backup time measurement described below in “3-2 Measuring the initial value of backup time”, proceed to “4. Operation”. Page 27 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 "7. Measuring the backup time" Page 61 The battery is discharged completely when the backup time is measur ed, so you need to recharge it befo re 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.) See also Charge the battery as described in "3-1 Charging the battery." Preparation for starting operation is now complete. 3-2 Measuring the initial value of backup time 3-3 Recharging the battery

Maintenance and inspection 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) 2. Method to check the battery There are 3 methods for checking the battery.

Perform a self-diagnostic test. (See page 32.)
Use the auto battery test function. (See page 32.)
Measure the backup time. (See page 47.) By measuring the backup time, the battery life can be determined more accurately. See also Measure the backup time according to "7-1 Measuring method of the backup time." Page 61 If the measured value is equal to the "initial value of the backup time" or less than half the value obtained from the graph of "Estimated backup time" on page 60, replace the battery.
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. 3. Guideline on the frequency of checking the battery (measuring the backup time) * The battery deteriorates even if it is stored. The higher the temperature is, the shorter the life becomes.

power supply. 2 UPS monitoring (operating status) The operating status of the UPS can be monitore d (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 notiﬁcation 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 operat- ing status is retained at shutdown in inactive state, so operation details ar e not lost.

6 Auto ﬁle save Files such as open Word and Excel documents are automatically saved at shut-

down. 7 Schedule operation Schedule settings can be made for UPS stop/start. 8 UPS setting change UPS settings (beep ON/OFF , etc.) can be changed. (Items that can be set vary according to the UPS.) 9 External command execution By executing commands at shutdown, items such as application pr ograms can be launched.

10 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. 11 Data log save Data of input/output voltage value, connection capacity, etc. is periodically saved as a log (the save frequency can be set).

12 Coordinated shutdown When a problem occurs with the power supply, multiple computers connected to

the UPS can coordinate to perform auto shutdown. 13 Output receptacle control The UPS output receptacles can be individually set to ON/OFF. (This is function is available only for BN100XR/BN150XR/BN240XR/BH60PCW/BH100PCW.) 14 Redundant power supply supportT wo or more UPS can be connected to computers equipped with redundant power supply. Shutdown is not performed when a power supply problem affects only one of the units. Shutdown is not performed when a power supply problem 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. 15 Remote UPS management The UPS can be managed remotely from a computer on the network. e h t g n i b i r c s e d l i a m e n oi t a c i f i t o n a , s r u c c o e r u l i a f r e w o p a s a h c u s m e l b o r p a n e h Wd n e s l i a M 6 1 problem can be sent to the system administrator. * If you do not use the UPS monitoring software or contact signal, you can disregard this section.

Using the UPS monitoring software and contact signal Explanation Operation start using the UPS monitoring software during scheduled stop If the unit starts operation during a scheduled stop period, the next set scheduled ON operation is cancelled after the power switch is turned OFF. Auto restart after OS shutdown by UPS monitoring software In the event of a power failur e, some PC models (see Note 1 below) automatically r estart immediately after the completion of the OS shutdown processing by the UPS monitoring software. In this case, the unit stops during restart or after startup, possibly damaging ﬁles and/or the hard disk. This problem can be avoided by disabling POWER MANAGEMENT in the BIOS settings. *1) PC models: This problem has been reported with MICRON Millennia Mme. When the PC does not start up automatically, select the “System startup at power restoration” setting (example: “Restore On AC/Power Loss) in the BIOS settings of your PC, and change to a “System startup after power restoration” setting (example: Power On). Individual BIOS setting methods and/o r displays may differ depending on the PC. For more information, refer to your PC instruction manual or the technical support center for your PC. When considering a system with automatic startup at power restoration, choose a PC that satisﬁes th e condition shown below. For more information on PC operation when input power is supplied, consult your PC instruction manual or contact the PC technical support center. <Condition> Without pressing the power switch, the PC starts up when input power is supplied. After shutdown processing in the event of a power failur e, the unit restarts automatically and supplies power once power is restored. If you do not want the devices connected to start up, turn OFF their switches while the power is out. The automatic restart setting can also be disabled in the included UPS monitoring software.

Using the UPS monitoring software and contact signal 6-5 Using the Contact Signal You can develop your unique system based on the following speciﬁcations to automate the process at the power failure. You can perform power failure and shutdown processing by allowing the system to detect the backup signal and low battery level signal, or you can use the trouble signal to perform failure notiﬁcation. You can stop the UPS by inputting the UPS Stop Signal from the system, and remote control start and stop of the UPS by using the Remote ON/OFF Signal. Also, this function is valid only when “connection communication” is selected for the “switching switch”. (See item 2 on page 35.) 1. Signal output The UPS has 5 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 Low battery level 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) Turns ON when battery deterioration is detected. BU-COM ON when a power failure occurs BL-COM ON when low battery level is detected TR-COM ON when an internal failure occurs WB-COM ON when battery deterioration is detected Click 4) After the settings are made, double-click the "Service" icon in "Control Panels". 5) Select the UPS service and click the "Start" button. By starting the alerter service, messenger service, and event log service in advance, the UPS service sends warning messages to the user and records a history of events such as power failures when they occur. When a power failure occurs, Windows shutdown is performed once the low battery level signal is detected. If the power is restored before the low battery level signal is detected, Windows shutdown is not performed and the normal monitoring state is restored.

Measuring the backup time (checking the discharge time of the battery) 7. Measuring the backup time (Checking the discharge time of the battery) (1) Connect the AC Input Plug of the UPS to a wall outlet (commercial power) and charge it for approximately 12 hours. If you operate the UPS for 12 hours or more, it is charged. If a power failure occurred during this period, charge it again. (2) Turn ON all devices connected to the power output to be “backed up during a power failure”. (Including devices connected to the AC outlet of your computer.) Operate them in a way in which it is allowable that power supply to the connected devices stops. For Windows Server 2003/XP/Me/2000/Windows NT/Linux/Mac: To be performed in case of hard drive stops. For Windows 98/95: Choose Shut Down of 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 disconnected. * The backup time you measure for the first time after purchase is the "initial value of the backup time." The backup time varies depending on the capacity of connected devices. After calculating the total capacity of connected devices, r efer 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) Unify the total capacity (power consumption) of connected devices to W (Watt). For the indication of connected devices, check your computer and the rear of the display. There are 3 types of indication: VA (Volt·Ampare) indication, A (Ampare) indication, and W indication. 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, conver t 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. IndicationV alue VA × power factor = W A × power factor × 100 = W 7-1 Measuring method of the backup time 7-2 Estimated backup time

Troubleshooting 8. Troubleshooting 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. 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 continuously. Perform the checks shown below if the unit is operating abnormally. If the unit continues to operate abnormally, please contact the shop of purchase. Problem 1. Check that the AC Input Plug is connected to the commercial power securely. 2. The AC Input Overcurrent Protection worked and opened. (If the black button is popped up, it is suspected that there are too many connected devices or there is a short in connected devices.) Disconnect all of the connected devices, push in the AC Input Overcurrent Protection Black 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 a beep and display" on page 30.) 3. Isn't the voltage of the wall outlet (commercial power) too low? Stop devices that consume a lot of power such as an air conditioner. Check the UPS, for example, by connect it to a wall outlet (comme rcial power) in another room or house. (It does not operate when the voltage is less than 90V.) Isn't charging insufficient? Perform the test after charging the battery for at least 12 hours. You can charge the battery by connecting the AC input plug of the UPS to a wall outlet (commercial power).) 1. The input power supply may be at fault. Connect the UPS to a wall outlet (commercial power) in another room or, if possible, another house and check it. Or, stop large devices such as a cooler. 2. Is a page printer (laser printer, etc.) connected? Because large current flows instantaneously in printers, normal backup is not possible. 1. The UPS generates some noise when performing backup. For displays susceptible to noise, distortion or white lines may occur, but the UPS is not at fault. 2. Grounding the UPS, computer, and display may improve this problem. The battery is judged to be dead in the auto battery test or the self-diagnostic test. Battery Mode cannot be performed and therefore replace the battery pack. There are too many connected devices. There are too many connected devices. Reduce the number of connected devices until “ ” is displayed on the status indicator. The UPS stopped because too many devices we re connected for 3 minutes or mor e, or because 120% was exceeded.
