Battery Test Description
When the input voltage 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 input frequency is within 46 to 64Hz, the UPS can be set at a
constant output frequency, 50 Hz or 60 Hz. The UPS will still charge
battery under this mode.
When the input voltage is beyond the acceptable range or power failure,
UPS will backup power from battery and alarm will beep every 4 seconds.
When input voltage is within acceptable range and bypass is enabled,
turn off the UPS and it will enter Bypass mode. Alarm beeps every two
minutes.
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". The line
between I/P and inverter icons will blink to remind users. This operation
is used to check the battery status.
