Common input mains
The UPS delivered in standard version has common input mains.
Only one input line (F1) supplies both rectifier and bypass input terminals.
Bear in mind that when the mains fuses are opened there is a supply failure to the rectifier as well
as to the automatic bypass and manual bypass.

Separate input mains (option)
On request, the UPS can be delivered for separate input mains.
Two independent lines (F2 and F3) supply separately the rectifier and the bypass inputs.
With this configuration, when the rectifier-input fuses are opened, the automatic bypass and the
maintenance bypass are supplied by the other line.
