Bypass mode
Standby mode
Fault mode
When input frequency is within 40 Hz to 70 Hz,
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, the UPS will backup
power from battery and alarm is sounding every
5 seconds.
When input voltage is within acceptable range
but UPS is overload, UPS will enter bypass mode
or bypass mode can be set by front panel. Alarm
is sounding every 10 seconds.
UPS is powered off and no output supply power,
but still can charge batteries.
When a fault has occurred, the ERROR icon and
the fault code will be displayed.
