2.3 Battery Mode (Utility failure condition)
In the event of a utility failure, the DC power to the inverter will be provided by the battery in order
to maintain a continuous AC power to the load for the specified time at the rated load (or longer at
a reduced load), until the battery voltage reaches the lower limit of the inverter operation capability.
During the discharge, the LCD screen displays the estimated time the battery can support the
critical load.
Prior to the battery completely discharging, the alarm “Stop operation” (load shutdown imminent)
warns the operator that the battery is almost discharged and the UPS is about to shut down.
“Stop Operation” time activation is settable.

The load is powered from the battery if the utility power does not conform to the specified parameters.
As soon as the AC input power recovers, the rectifier starts up automatically (soft-start) supplying
the DC power and recharging the battery.
During utility mains recovery, in case a utility power failure is major than the back-up time, the
battery is recharged enough to ensure a minimum time of operation with the present load, the
inverter starts automatically and the load will be transferred from the static bypass back to the
inverter (normal mode).
No additional operations are necessary.
