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. The load is assumed by the inverter automatically without operator
intervention.
In the event of a power failure, the rectifier will de-energize and the batteries will discharge
into the inverter and maintain power to the critical until a) the battery capacity expires and
the inverter turns off, or b) input power is restored after which the converter will power the
critical load and simultaneously recharge the batteries. Figure 1.3 illustrates the flow
diagram during battery operation.
