Use the test function to check both the operation of the UPS and
the condition of the battery.
In AC operating mode,the level indicator will show the actual load
connected to this UPS normally.Press and hold the "Test" switch
on the front panel for more than 2 seconds,this UPS will enter into
testing mode. The battery will provide power to the load during this
period.Testing mode will check the status of battery and operation
of UPS,last for 10 seconds and transfer back to normal status
automatically.
Testing mode can not performed if the load connected is greater
than overload or the charging voltage is lower than
22Vdc (model:700W/1000VA) or 88Vdc (model:2100W/3000VA).
NOTE
Test
In battery backup mode, the level indicator will show the battery
capacity level and the alarm beeps normally. Press and hold the
" Test "switch on the front panel for more than 2 seconds. The

Installation and Operating Instruction
AC Mode
The UPS delivers power to the loads derived from the utility and maintains proper
battery charge. It also regulates the output voltage to within a narrow range and
serves to isolate the load from surges and electrical noise brought by the utility wiring.
On-Battery Mode
The UPS operates on battery when the line voltage or frequency has fallen outside
the limits. Local users are alerted to this mode of operation by visual and audible
indicators. The UPS provides power to the load from the battery and through its
inverter and the output voltage and frequency of the UPS are regulated within a
narrow band.
