1) When the UPS is running in battery mode, the buzzer beeps once
every 4 seconds. If the “ON” button on the front panel is pressed
for more than 1 second again, the buzzer will stop beeping (in
silence mode). Press the “ON” butto n once again for more than 1
second to resume the alarm function.
2) If the UPS is working in battery mode for the input line voltage is
higher than the SPEC range, the alarm symbol - “High!” will be
shown; if the UPS is working in battery mode for the input line
voltage is lower than the SPEC range, the alarm symbol - “Low!”
will be shown; if the input line voltage is lost, both “High!” and
“Low!” would not be shown but the input voltage and frequency are
shown as zero.
The display of battery test mode is same as battery mode, but “High!”
and “Low!” would not be shown unless the input line voltage is higher
or lower than the SPEC range during the time of battery test. The

If output overloaded, the load percent is shown and alarm will keep
twice every seco nd. Yo u should get rid of some unnecessary loads
one by one to decrease the loads connected to the UPS less than
90% of its nominal power capacity.
Note: Please follow the following steps to connect the generator
Activate the generator and wait until the operation is stable before
supplying power of the generator to the UPS (be sure that the UPS
is in idle mode). Then turn on the UPS according to the start-up
procedure. After the UPS is turned on, then the loads can be
connected to the UPS one by one.
The power capacity of the AC generator sho uld be at least twice of
the UPS capacity.
