a) The battery capacity expires and the inverter turns off, or
b) Input power is restored after which the converter will power the inverter and critical load
and simultaneously recharge the batteries.
A fully charged battery will provide power for the specified time at the rated load, or longer, at a
reduced load.
When power is restored after a low battery shutdown, the UPS converter(s)* automatically
restarts operation, the charger(s)* recharges the batteries and the Inverter(s)* is automatically
restarted without operator intervention. Load is automatically assumed by the inverter without
operator intervention.
The power drawn by the load is equally shared between all UPS regardless of the presence
or absence of the UPS that is (are) in battery operation or not whenever the system is in the
Parallel Operation. .
