Choice Of Ac Input For The Power Supply - GE Digital Energy SitePro 400 VAC CESeries 7 Operating Manual

4.8.2

Choice of AC input for the power supply

The control and regulation circuits are supplied by two separate power supplies:
one powered from AC mains input voltage and another powered by DC battery voltage.
The AC power supply can be powered either by bypass mains input (standard version, suitable in most
cases) or rectifier mains input.
The input of the AC Power Supply AC must be supplied from the mains input rectifier:
•
In case the UPS is used as frequency converter (mains input bypass terminals not powered);
•
With separate AC inputs, following a complete battery discharge, the UPS system must be restarted
only having the rectifier-input terminals powered.
