When the bypass voltage/frequency is out of
acceptable range or bypass is disabled (or
forbidden), UPS will enter into no-output mode if
powering on or turning off the UPS. It means the UPS
has no output. Alarm beeps every two minutes.
When the bypass voltage/frequency is within
acceptable range and bypass is enabled, UPS will
enter into bypass mode if powering on or turning off
the UPS. Alarm beeps every two minutes.
When the input voltage/frequency is within
acceptable range, UPS will provide pure and stable
AC power to output. The UPS will also charge the
battery at AC mode.
When the input voltage/frequency is within
acceptable range and ECO mode is enabled, UPS
will bypass voltage to output for energy saving.
When the CVCF mode is enabled, the inverter will
output constant frequency (50 Hz or 60 Hz). At this
mode, the UPS will have no bypass output but still
charge battery.
When the input voltage/frequency is out of the
acceptable range or power failure, UPS will backup
power from battery and alarm will beep every 4
seconds.
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”. This operation is used
to check the battery status.
