3. Operation
3.1 Operating mode
ON-LINE mode
This is the standard operating mode, set by default in the factory.
It makes use of electronic double conversion of the input power.
Two possible cases:
LED is ON: AC input power is available. Power is drawn
from the distribution system and supplied to the protected
equipment via the UPS.
LED is ON: AC input power is not available. Power is drawn
from the battery and supplied to the protected equipment.

ECO mode
The main advantage of this mode is that it reduces the consumption of electrical power. The protected
equipment is supplied directly by the AC-power source as long as it remains within the tolerances set
by the user.
ECO mode is selected and tolerance levels are set using the "UPS Driver" software for UPS
personalization (see section 3.5).
Three possible cases:
The AC-power source is within the set tolerances. The protected
equipment is supplied directly by the AC-power source, via the
automatic bypass. LED is ON.
The AC-power source is not within the set tolerances. The UPS
automatically shifts to ON-LINE mode. LED is ON.
The AC-power source is not available. LED is ON.
The battery supplies power to the protected equipment.
