5.8.2 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 power down, the UPS system must be restarted only
having the rectifier-input terminals powered.
