The third digit is the internal battery and external battery identification, 0 is the standard built-in battery machine. The lower left corner is the ratio of battery capacity and the right is the percentage and ratio of load.


Main operation mode of UPS

Utility mode

UPS After power on, if the power supply is normal, UPS It will enter the utility mode. The indicator light of the panel running in the city power mode will be on.

If the load capacity is greater than one hundred %The buzzer calls every half a second to remind you that you have received too much load. You should remove the unnecessary load one by one until UPS Load less than one hundred %。

If the battery indicator is flashing, it means UPS If the battery is not connected or the battery voltage is too low, check whether the battery is connected well and press the function key two Second, carry out battery self-test. Confirm that the connection is correct. It may be battery failure or aging. Please refer to the troubleshooting table.

       Precautions for receiving and sending motor

A Start the generator and connect the output power of the generator to the output power supply of the generator after it runs stably UPS Input (at this time to determine UPS No load), then press start key start-up UPS UPS After startup, one by one Access Load, non professionals are not allowed to use terminal block for load wiring, in order to avoid electric shock.

B . it is suggested that UPS To double the capacity of the generator

Battery mode

When the mains power is not connected or started UPS During operation, when the power supply is abnormal, UPS It will switch to battery mode.

When running in battery mode, the buzzer four If you press the function key continuously at this time two More than seconds, UPS Execute the silencing function, the buzzer will no longer sound the alarm, and then continue to press the function key two More than seconds, the alarm is restored.

When the battery voltage drops to the warning potential, the buzzer will sound once every second to prompt the user that the battery capacity is insufficient, so the load operation should be carried out and the load should be removed one by one).

If the mains power indicator light flashes, it means that the voltage or frequency of the mains power has exceeded the normal range.

bypass mode

When UPS In case of overload or short circuit fault in the utility mode, the machine will automatically switch to the bypass mode for power supply here The mains and bypass lights are on, UPS Call every two minutes.

UPS When working in bypass mode, there is no backup function. At this time, the power used by the load is directly supplied by the power system through filtering. .

Operation operation

Power on operation

Note: Although the battery is fully charged when leaving the factory, it will be lost after transportation and storage. It is recommended to use it for * * times UPS Charge the battery first ten Hours or consult the battery manufacturer to ensure that there is enough spare time.

Press and hold the power on key for more than 1 second, and the ups will start up. When the UPS is turned on, it will conduct self-test. At this time, the load / battery capacity indicator lights on the panel will be on, and then turn off one by one from right to left. After the self-test is completed, it will enter the normal working state.    

Shutdown operation

Press on continuously / Shut down key one More than seconds, UPS Shut down. When shutting down UPS Self test will be carried out. At this time, a row of indicator lights above the panel will be on and off one by one No display on rear panel UPS No output voltage.

Battery self test operation

UPS During operation, the user can manually start the battery self-test function To check the battery status. The method of starting battery self-test is as follows:

Through the function key

In mains mode, press the function key continuously two More than seconds, UPS Switch to the battery mode and perform battery self-test 1# 6# The indicator lamp flashes periodically. Default battery self test duration ten second During battery self-test, in case of battery failure, UPS It will automatically switch to the commercial power mode.

Through the background monitoring software

The user can also start the battery self-test software.

Silencing operation

When UPS Working in battery and bypass mode, UPS Alarm beep (in battery mode, one call in four seconds, one call in one second when battery voltage is very low, and one call in two minutes when bypass output). The user can manually perform the silencing or start the alarm. Note: in battery mode, only the alarm tone of one call in four seconds can be eliminated.

The method is as follows:

Through the function key

In battery and bypass mode, press the function key continuously two Seconds or more until you hear the buzzer Di A sound, when UPS When there is an alarm tone, this action cancels the alarm tone UPS When there is no alarm tone, this action will start the alarm tone.

Through the background monitoring software

Users can also use background monitoring software to silence.

Maintenance and maintenance

Routine maintenance

Keep the environment clean UPS Cause dust or chemical contamination.

Check the terminals of input and output cables every six months. Check carefully and measure whether the contact is good.

Regularly check the working state of the fan to prevent foreign matters from blocking the air outlet. If it is damaged, it should be replaced in time.

regular inspect UPS Working conditions

If the power supply is normal, UPS It should work in the utility mode; if the mains power is abnormal, UPS It should work in battery mode. And there is no fault display in both working states.

regular inspect UPS Switching operation mode

Disconnect the mains power input and simulate the mains power failure, UPS Switch to the battery power supply mode and operate normally; then connect the mains power input, UPS It should be switched back to the utility mode and work normally.

regular inspect UPS The indicator light of

During the above two inspections, the UPS Whether the indicator light of the display is consistent with its actual operation mode.

Battery maintenance

The battery is UPS An important part of the system. The battery life depends on the ambient temperature and the number of discharges. High temperature or deep discharge can shorten the service life of the battery.

Battery should be used to keep the ambient temperature at fifteen reach twenty-five between.

If not used for a long time UPS , it is recommended that every three Charge once a month.

Under normal conditions, the service life of the battery is three reach five If the battery is found to be in poor condition, it must be replaced early, and the battery replacement must be operated by professionals.


When your UPS In case of abnormal conditions, please check and remove the fault according to the table below. If the problem still exists, please contact the customer Service Center Contact.

Fault alarm and code:

01 Inverter output short circuit 09 Inverter soft start timeout
