Mains power mode operation process
5.5 Battery mode / battery self test mode
In battery mode, the batteries go through DC/ DC boost and supply DC voltage to
the inverter, and then supply AC power to the load via the inverter circuit.
LED indicator in battery mode is as shown in the figure below: the inverter LED
indicator (green) is illuminated and battery LED indicator (yellow) is illuminated, and
alarm LED indicator (red) flashes while giving alarm, meanwhile LCD display bAT
characters.
When the batteries process in manual self-test and regular self-test, the inverter
indicator, bypass indicator, battery indicator and fault indicator will be illuminated
circularly, meanwhile LCD display bAT characters.
When the mains circuit input is abnormal, the UPS transfers to battery mode
immediately. When the battery voltage is less than shutdown point and bypass is
normal in battery mode, the UPS transfers to bypass mode to supply uninterruptible
power to the load.
