Referring to Figure 1.3: In the event of AC input source failure or interruption, the converter will de-energize and the battery will immediately discharge and supply DC power to the inverter to maintain continuous AC power to the load. This operation will continue until:

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 converter automatically restarts operation, recharges the batteries and the Inverter 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 system UPS during battery operation.
