3-4. Single UPS Operation
1. 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 (the
step is only available for long-run model). Then set the line input breaker at “ON”position (for dual
input unit, also set the bypass input breaker at “ON”). In the meanwhile, the fan is running and the
UPS starts power on mode for initialization. Several seconds later, UPS operates 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 you
switch on the input breaker. In Bypass mode, the load is not protected by UPS. To protect your
precious devices, you should turn on the UPS. Please refer to next step.
2) Press and hold the “ON” button for 0.5s until the buzzer will beep once to turn on the UPS.
3) A few seconds later, the UPS will enter AC mode. If the utility power is abnormal, the UPS will
operate in Battery mode without interruption.
NOTE: When the UPS is running out of battery, it will shut down automatically in Battery mode. When
the utility power is restored, the UPS will automatically restart in AC mode.
2. Turn on the UPS without utility power supply (in Battery mode)
1) Make sure that the two groups battery are connected correctly as ”+, GND,-”order and 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 and UPS will enter power on mode.
After initialization UPS will enter No Output mode. Then, press and hold the “ON” button for 0.5s
until the UPS is on and the buzzer will beep once.
3) A few seconds later, the UPS will be turned on and enter Battery mode.

12
3. Connect devices to UPS
After 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 total
load level.
2) If it is necessary to connect the UPS to the inductive loads such as a printer, the in-rush current
should be calculated carefully in case that it meets the maximum capacity of the UPS because of
the high power consumption of this kind of load.
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 the
total loads connected to the UPS less than 80% of its nominal power capacity to prevent overload
for system safety.
5) If the overload time exceed acceptable duration listed in spec at AC mode, the UPS will be
automatically transferred to bypass mode. After the overload device is removed, it will return to AC
mode. If the overload time exceeds acceptable duration listed in spec at battery mode, the UPS will
show fault status. At this time, if bypass is enabled, the UPS will power the load via bypass. If
bypass function is disabled or the input power is not within acceptable range of bypass mode, it will
cut off the connection of output directly.
4. Charge the batteries
1) After the UPS is connected to the utility power and turned on in AC mode, the charger will charge
the batteries automatically except in Battery mode, during battery self-test, overload or high
battery voltage duration.
2) Be sure to charge batteries at least 10 hours before operation. Otherwise, the backup time may be
shorter than expected time.
3) Make sure the battery numbers set on the control board (Please refer to the section 3-4-12 for
detailed setting) is consistent to real connection.
5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. If the
battery capacity is more than 25%, the buzzer will beep once every 4 seconds; If the battery
voltage drops to the alarm level, the buzzer will beep quickly (once every second) to remind users
that the battery is at low level and the UPS will shut down automatically soon. Users could switch
off some non-critical loads to disable the shutdown alarm and prolong the backup time. If there is
no more loads to be switched off at that time, it’s suggested to shut down all loads as soon as
possible to protect the devices or save data. Otherwise, there is a risk of data loss or load failure.
2) In Battery mode, if buzzer sounds annoying, users can press the Mute button to disable the buzzer.
3) The backup time of the long-run model depends on the capacity of external battery.
4) The backup time may vary from different environmental temperature and load type.
5) When setting backup time for 16.5 hours (default value from LCD panel), after discharging 16.5
hours, UPS will shut down automatically to protect the battery. This battery discharge protection
can be enabled or disabled through LCD panel control. (Refer to 3-7 LCD setting section)
6. Test the batteries
1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode, you can
press the “Test”button to activate battery self-test of the UPS.
2) Users also can set battery self-test through monitoring software.
7. Turn off the UPS with utility power supply in AC mode
1) Turn off the inverter of the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will
beep once. The UPS will turn into Bypass mode.
NOTE 1: If the UPS is set to enable the bypass output, it will bypass voltage from utility power to
output terminal even though the UPS (inverter) is off.

13
NOTE 2: After turning off the UPS, please be aware that the UPS is working in Bypass mode and
there is a risk of power loss for connected devices.
2) In Bypass mode, output voltage of the UPS is still existing. In order to cut off the output, switch off
the line input breaker (for dual input unit, also switch off the bypass line breaker). A few seconds
later, if there is no display shown on the display panel, UPS is completely off.
8. Turn off the UPS without utility power supply in Battery mode
1) Turn off the UPS by pressing “OFF” button for at least 0.5s until the buzzer will beep once.
2) The power of the output will be cut off. There is no display shown on the display panel.
9. Mute the buzzer
1) To mute the buzzer, please press the “Mute” button for at least 0.5s. If you press it again after the
buzzer 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 the
details.
10. Operation in warning status
1) When Fault LED flashes and the buzzer beeps once every second, it means that some problems
occur during UPS operation. Users can get the warning indication from LCD panel. Please check the
trouble 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 the
details.
11. Operation in Fault mode
1) When Fault LED lights on and the buzzer beeps continuously, it means that there is a fatal error in
the UPS. Users can get the fault code from display panel. Please check the trouble shooting table in
chapter 4 for details.
2) Please check the loads, wiring, ventilation, utility, battery and so on after the fault occurs. Don’t try
to turn on the UPS again before solving the problems. If the problems can’t be fixed, please contact
the distributor or service center immediately.
3) For emergency case, please cut off the connection from utility, external battery, and output
immediately to avoid more risk or danger.

Parameter 3: Output voltage
You may choose the following output voltage in parameter 3:
208: Presents output voltage is 208Vac
220: Presents output voltage is 220Vac
230: Presents output voltage is 230Vac
240: Presents output voltage is 240Vac

Parameter 2: Output Frequency
Setting the output frequency. You may choose following three
options in parameter 2:
50.0Hz: The output frequency is set to 50.0Hz.
60.0Hz: The output frequency is set to 60.0Hz.
ATO: If selected, output frequency will be set according to the
latest frequency of normal utility. If it is from 46Hz to 54Hz, the
output frequency will be 50.0Hz. If it is from 56Hz to 64Hz, the
output frequency will be 60.0Hz. ATO is default setting.
Parameter 3: Frequency mode
Setting output frequency at CVCF mode or not CVCF mode. You
may choose the following two options in parameter 3:
CF: Setting UPS to CVCF mode. If selected, the output frequency
will be fixed at 50Hz or 60Hz according to the setting in parameter
2. The input frequency is from 46Hz to 64Hz.
NCF: Setting UPS to normal mode (not CVCF mode). If selected,
the output frequency will be synchronized with the input
frequency within 46~54 Hz at 50Hz or within 56~64 Hz at 60Hz
according to the setting in parameter 2. If 50 Hz selected in
parameter 2, UPS will transfer to battery mode when input
frequency is not within 46~54 Hz. If 60Hz selected in parameter 2,
UPS will transfer to battery mode when input frequency is not
within 56~64 Hz.
*If Parameter 2 is ATO, the Parameter 3 will show the current
frequency.
03: Voltage range for bypass

Setting
Parameter 2: Set the acceptable low voltage for bypass. Setting
range is from 176V to 209V and the default value is 176V.
Parameter 3: Set the acceptable high voltage for bypass. Setting
range is from 231V to 276V and the default value is 264V.
