Single UPS Operation1. Turn on the UPS with utility power supply (in AC mode)1) After power supply is connected correctly, set the breaker of the battery pack at “ON” position (thestep only available for long-run model). Then set the input breaker at “ON” position. At this timethe fan is running and the UPS enter to power on mode for initialization, several seconds later, UPSoperates in Bypass mode and supplies power to the loads via the bypass.NOTE: When UPS is in Bypass mode, the output voltage will directly power from utility after youswitch on the input breaker. In Bypass mode, the load is not protected by UPS. To protect yourprecious devices, you should turn on the UPS. Refer to next step.2) Press and hold the “ON” button for 0.5s to turn on the UPS and the buzzer will beep once.3) A few seconds later, the UPS will enter to AC mode. If the utility power is abnormal, the UPS willoperate in Battery mode without interruption.NOTE: When the UPS is running out battery, it will shut down automatically at Battery mode. When theutility power is restored, the UPS will auto restart in AC mode.2. Turn on the UPS without utility power supply (in Battery mode)1) Make sure that the breaker of the battery pack is at “ON” position (only for long-run model).2) Press the “ON” button to set up the power supply for the UPS, UPS will enter to power on mode.After initialization UPS will enter to No Output mode, then Press and hold the “ON” button for 0.5sto turn on the UPS, and the buzzer will beep once.3) A few seconds later, the UPS will be turned on and enter to Battery mode.3. Connect devices to UPSAfter the UPS is turned on, you can connect devices to the UPS.1) Turn on the UPS first and then switch on the devices one by one, the LCD panel will display totalload level.2) If it is necessary to connect the inductive loads such as a printer, the in-rush current should becalculated carefully to see if it meets the capacity of the UPS, because the power consumption ofthis kind of loads is too big.3) If the UPS is overload, the buzzer will beep twice every second.4) When the UPS is overload, please remove some loads immediately. It is recommended to have thetotal loads connected to the UPS less than 80% of its nominal power capacity to prevent overload9

for system safety.5) If the overload time is over acceptable time listed in spec at AC mode, the UPS will automaticallytransfer to Bypass mode. After the overload is removed, it will return to AC mode. If the overloadtime is over acceptable time listed in spec at Battery mode, the UPS will become fault status. At thistime, if bypass is enabled, the UPS will power to the load via bypass. If bypass function is disabledor the input power is not within bypass acceptable range, it will cut off output directly.4. Charge the batteries1) After the UPS is connected to the utility power, the charger will charge the batteries automaticallyexcept in Battery mode or during battery self-test.2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may beshorter than expected time.3) Make sure the battery numbers setting on the control board (Please refer to the section 3-4-12 fordetailed setting) is consistent to real connection.5. Battery mode operation1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. If thebattery capacity is more than 25%, the buzzer will beep once every 4 seconds; If the batteryvoltage drops to the alarm level, the buzzer will beep quickly (once every sec) to remind users thatthe battery is at low level and the UPS will shut down automatically soon. Users could switch offsome non-critical loads to disable the shutdown alarm and prolong the backup time. If there is nomore load to be switched off at that time, you have to shut down all loads as soon as possible toprotect the devices or save data. Otherwise, there is a risk of data loss or load failure.2) In Battery mode, if buzzer sound annoys, users can press the Mute button to disable the buzzer.3) The backup time of the long-run model depends on the external battery capacity.4) The backup time may vary from different environment temperature and load type.5) When setting backup time for 16.5 hours (default value from LCD panel), after discharging 16.5hours, UPS will shut down automatically to protect the battery. This battery discharge protectioncan be enabled or disabled through LCD panel control. (Refer to 3-6 LCD setting section)6. Test the batteries1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode, you couldpress the “Test” button to let the UPS do battery self-test.2) Users also can set battery self-test through monitoring software.3) If the UPS is at battery self-test, the LCD display and buzzer indication will be the same as atBattery mode except that the battery LED is flashing.7. Turn off the UPS with utility power supply in AC mode1) Turn off the inverter of the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer willbeep once. The UPS will turn into Bypass mode.NOTE 1: If the UPS has been set to enable the bypass output, it will bypass voltage from utilitypower to output terminal even though you have turned off the UPS (inverter).NOTE 2: After turning off the UPS, please be aware that the UPS is working at Bypass mode andthere is risk of power loss for connected devices.2) In Bypass mode, output voltage of the UPS is still present. In order to cut off the output, switch offthe input breaker. A few seconds later, there is no display shown on the display panel and UPS iscomplete off.10

8. Turn off the UPS without utility power supply in Battery mode1) Turn off the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will beep once.2) Then UPS will cut off power to output and there is no display shown on the display panel.9. Mute the buzzer1) To mute the buzzer, please press the “Mute” button for at least 0.5s. If you press it again after thebuzzer is muted, the buzzer will beep again.2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for thedetails.10. Operation in warning status1) When Fault LED flashes and the buzzer beeps once every second, it means that there are someproblems for UPS operation. Users can get the warning indicator from LCD panel. Please check thetrouble shooting table in chapter 4 for details.2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for thedetails.11. Operation in Fault mode1) When Fault LED illuminates and the buzzer beeps continuously, it means that there is a fatal error inthe UPS. Users can get the fault code from display panel. Please check the trouble shooting tablein chapter 4 for details.2) Please check the loads, wiring, ventilation, utility, battery and so on after the fault occurs. Don’t tryto turn on the UPS again before solving the problems. If the problems can’t be fixed, please contactthe distributor or service people immediately.3) For emergency case, please cut off the connection from utility, external battery, and outputimmediately to avoid more risk or danger.12. Operation of changing battery numbers1) This operation is only available for professional or qualified technicians.2) Turn off the UPS. If the load couldn’t be cut off, you should remove the cover of maintenancebypass switch on the rear panel and turn the maintenance switch to “BPS” position first.3) Switch off the input breaker, and switch off the battery breaker (only available for long-run model).4) Remove the cabinet cover, and disconnect battery wire for standard model.

• 01: Output voltageInterface• 02: Output frequencyInterface60 Hz, CVCF mode50 Hz, Normal modeATO• 03: Output phase angleInterfaceSettingParameter 3: Output voltageYou may choose the following output voltage in parameter 3:100: Presents output voltage is 100Vac110: Presents output voltage is 110Vac115: Presents output voltage is 115Vac120: Presents output voltage is 120Vac127: Presents output voltage is 127VacSettingParameter 2: Output FrequencySetting the output frequency. You may choose following threeoptions in parameter 2:50.0Hz: The output frequency is setting for 50.0Hz.60.0Hz: The output frequency is setting for 60.0Hz.ATO: If selected, output frequency will be decided according tothe latest normal utility frequency. If it is from 46Hz to 54Hz, theoutput frequency will be 50.0Hz. If it is from 56Hz to 64Hz, theoutput frequency will be 60.0Hz. ATO is default setting.Parameter 3: Frequency modeSetting output frequency at CVCF mode or not CVCF mode. Youmay choose following two options in parameter 3:CF: Setting UPS to CVCF mode. If selected, the output frequencywill be fixed at 50Hz or 60Hz according to setting in parameter 2.The input frequency could be from 46Hz to 64Hz.NCF: Setting UPS to normal mode (not CVCF mode). If selected,the output frequency will synchronize with the input frequencywithin 46~54 Hz at 50Hz or within 56~64 Hz at 60Hz according tosetting in parameter 2. If 50 Hz selected in parameter 2, UPS willtransfer to battery mode when input frequency is not within46~54 Hz. If 60Hz selected in parameter 2, UPS will transfer tobattery mode when input frequency is not within 56~64 Hz.*If Parameter 2 is ATO, the Parameter 3 will show the currentfrequency.SettingParameter 2: Output phase angle settingCP: Enable CP function. If selected, the output phase angle will befixed at 0°, 120°,180°or 240°according to setting in parameter 3 nomatter the input phase angle is same as or different from theoutput phase angle set value. If “CP” is selected, after exiting thesetting menu, “CP” will always appear on the screen at AC mode,and there will be no bypass output at any time.This setting is useful when you need to configure this UPS to “singlephase in / two-phase out”.ATO: The output phase angle will be initialized automatically to thesame as the valid input phase angle* every time UPS is powered onwith mains utility available. When UPS is turned to line mode (ACmode), the output phase angle will keep the same as input phaseangle.*NOTE: Only 0/120/180/240°are the valid phase angle.When UPS is transferred to battery mode from AC mode, the outputphase angle will be kept. Then, if the UPS transfers back to ACmode, the input phase angle must be the same to the output phase14

• 04: Output phases (L1, L2) parallel functionInterfaceangle.When UPS shuts down at battery mode, the latest phase angle willbe saved in chip. If the UPS is turned on again directly at batterymode (without utility power), the output phase angle will be sameto the saved latest phase angle. If the UPS is powered up withmains utility, the UPS will adapt the connected valid utility inputphase angle and discard the saved value.ATO is default setting.Parameter 3: Phase angleIf parameter 2 is set to “CP”, you may choose the following outputphase angle in parameter 3:0: Presents output phase angle is fixed with 0°.120: Presents output phase angle is fixed with 120°.180: Presents output phase angle is fixed with 180°.240: Presents output phase angle is fixed with 240°.If parameter 2 is set to “ATO”, the output phase angle will bedisplayed as detected valid input phase angle when UPS is poweredon with mains power. Otherwise, it will display the latest phaseangle saved* in chip.*The default setting is 120° when UPS is powered on in Batterymode.SettingParameter 2:OP.P: Indicates parallel functions for two output phases (L1, L2).Parameter 3:DIS: Disable output parallel function. If selected, output L1 and L2must NOT be connected. It is default setting.If you do not connect output L1 and L2 together, please set it to“DIS”. At this time, even the output phase angle is set to 0°, thereare two-phase outputs (L1 phase & L2 phase), which are stillindependent. That means each phase power capacity is only half ofthe total power capacity of the UPS.ENA: Enable parallel function to allow connecting two outputs inparallel to get only one phase output with 100% of UPS totalcapacity. When this function is enabled, output L1 and L2 MUST beconnected and only 0°is valid output phase angle. This setting willbe ignored if the output phase angle is set or initialized at 120°/180°/240°.If you connect output L1 and L2 together, please set it to “ENA”.Then, the output phase becomes a real single phase. The input L1and L2 also must be connected together as a single phase. Thatmeans the UPS is configured to a 1/1(single phase in / single phaseout) UPS. Then, the output phase angle is NOT allowed to set to“CP 120”, “CP 180”, or “CP 240”. If the output phase angle isprogrammed to “CP 0”, there will be no bypass. If the output phaseangle is programmed to “ATO”, there will be automatic bypass.15

The UPS will also charge the battery at ACmode.LCD displayECO mode Description When the input voltage is within voltage regulation range and ECO mode isLCD displayenabled, UPS will bypass voltage to output for energy saving.CVCF mode Description When the output frequency is set to “CF”, the inverter will generate constantfrequency (50 Hz or 60 Hz). The UPS will have no bypass output but will stillcharge battery under this mode.LCD display20

CP status Description When output phase angle is set to be constant with 0/120/180/240, the UPSwill display “CP”. In this status, the UPS could accept the input phase angledifferent from the setting value. So, there will be no bypass output in thisstatus.LCD displayBattery mode Description When the input voltage or frequency is beyond the acceptable range orpower failure, UPS will backup power from battery and alarm will beep every4 seconds.LCD displayBypass mode Description When input voltage is within acceptable range and bypass is enabled, turnLCD displayoff the UPS and it will enter Bypass mode. Alarm beeps every two minutes.Battery Test Description When UPS is in AC mode or CVCF mode, press “Test” key for more than 0.5s.Then the UPS will beep once and start “Battery Test”. The line between I/Pand inverter icons will blink to remind users. This operation is used to checkthe battery status.21

LCD displayWarningstatusDescriptionLCD displayIf some errors occur in the UPS (but it is still running normally), it will showone more screen to represent the warning situation. In the warning screen,the icon will be flashing. It can show up to 3 error codes and each codeindicates one error. You can find the code meaning in the warning codetable.Fault status Description When fault occurs in UPS, the inverter will be blocked. It will display faultcode in screen, and the icon will illuminate. You can find the codemeaning in the fault code table.LCD display3-8.

4. Trouble ShootingIf the UPS system does not operate correctly, please solve the problem by using the table below.Symptom Possible cause RemedyNo indication and alarm in the frontdisplay panel even though the mains isnormal.The iconand the warning codeflash on LCD display and alarmbeeps every second.The icon and flash onLCD display and alarm beeps everysecond.The icon and flash onLCD display and alarm beeps twiceevery second.Fault code is shown as 43. The iconlights on LCD display andalarm beeps continuously.Fault code is shown as 14, 15, or 17.The iconlights on LCDdisplay, and alarm beeps continuously.Other fault codes are shown on LCDdisplay and alarm beeps continuously.Battery backup time is shorter thannominal valueThe icon and flash on LCDdisplay and alarm beeps every second.The AC input power is notconnected well.EPO function is enabled andEPO switch is in “OFF” status,or the jumper is open.The external or internalbattery is incorrectlyconnected.UPS is overload.UPS is overloaded. Devicesconnected to the UPS are feddirectly by the electricalnetwork via the Bypass.After repetitive overloads, theUPS is locked in the Bypassmode. Connected devices arefed directly by the mains.UPS is overload too long andbecomes fault. Then UPS shutdown automatically.The UPS shut downautomatically because shortcircuit occurs on the UPSoutput.A UPS internal fault hasoccurred.Batteries are not fully chargedBatteries defectFan is locked or not working;or the UPS temperature is toohigh.Check if input cable firmlyconnected to the mains.Set the circuit in closedposition to disable EPOfunction.Check if all batteries areconnected well.Remove excess loads from UPSoutput.Remove excess loads from UPSoutput.Remove excess loads from UPSoutput first. Then shut downthe UPS and restart it.Remove excess loads from UPSoutput and restart it.Check output wiring and ifconnected devices are in shortcircuit status.Contact your dealerCharge the batteries for atleast 7 hours and then checkcapacity. If the problem stillpersists, consult your dealer.Contact your dealer to replacethe battery.Check fans and notify dealer.24

Symptom Possible cause RemedyThe warning code 02 is shown and theicon flashes on LCD. The alarmbeeps every second.The input neutral wire isdisconnected.The second phase input fuse isbroken.Check and fix the input neutralconnection. If the connection isok and the alarm is stilldisplaying, please refer to theLCD setting section to enterthe “neutral loss detection”menu. If “CHE” is displayed inthe parameter 3, please pressthe “Enter” key to make the“CHE” flash and press the“Enter” key again to mute theUPS. If the alarm still exists,please check the second phaseinput fuse.Replace the fuse.25

5. Storage and Maintenance5-1. StorageBefore storing, charge the UPS at least 7 hours. Store the UPS covered and upright in a cool, drylocation. During storage, recharge the battery in accordance with the following table:Storage Temperature Recharge Frequency Charging Duration-25°C - 40°C Every 3 months 1-2 hours40°C - 45°C Every 2 months 1-2 hours5-2. MaintenanceThe UPS system operates with hazardous voltages. Repairs may be carried out only by qualifiedmaintenance personnel.Even after the unit is disconnected from the mains, components inside the UPS system are stillconnected to the battery packs which are potentially dangerous.Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify thatno current is present and no hazardous voltage exists in the terminals of high capability capacitor such asBUS-capacitors.Only persons are adequately familiar with batteries and with the required precautionary measuresmay replace batteries and supervise operations. Unauthorized persons must be kept well away from thebatteries.Verify that no voltage between the battery terminals and the ground is present before maintenanceor repair. In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages mayoccur between the battery terminals and the ground.Batteries may cause electric shock and have a high short-circuit current. Please remove allwristwatches, rings and other metal personal objects before maintenance or repair, and only use toolswith insulated grips and handles for maintaining or repairing.When replace the batteries, install the same number and same type of batteries.Do not attempt to dispose of batteries by burning them. This could cause battery explosion. Thebatteries must be rightly deposed according to local regulation.Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes.
