This UPS outputs power input from commercial power as it is and charges the battery at the same time. If a
power failure or voltage variation occurs, the UPS automatically switches to operation using the battery and
continues power output. At this time, the beeper sounds intermittently. When the power is recovered, normal
operation using commercial power is automatically recovered. (The beeper stops.) You do not have to perform
any operation.
