Normal Mode Operation
The rectifier/charger converts the supplied AC power into DC (bus) power that is
then supplied to the inverter and the battery charger. The DC to AC inverter then
supplies continuous, noise free AC power to the critical loads. The inverter output is
synchronized with the bypass AC power source provided that the bypass AC power
source is within the specified frequency range.

Back-up Mode Operation
As the batteries are connected to the DC bus they supply energy to the inverter via
this DC bus, the AC power will remain constant and continuous without interruption
to the loads when the AC fails or falls out side of the operating parameters. Upon
return of the supplied AC input power the ELI. The rectifier will automatically assume
the DC load (charger, inverter) from the batteries. The ELI will simultaneously supply
power to the inverter and the battery charger to replenish the batteries.
