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
absence of the UPS that is (are) in battery operation or not whenever the system is in the Parallel
Operation.
