UPS EVO DSP MM Rack Tower
The Bypass mode is identified by:
•
The graphic LCD panel shows the functioning during
Bypass mode.
•
An acoustic signal every 10 seconds.
During Bypass mode, loads are fed directly from AC Input line. Therefore no protection
against AC Input line disturbances or interruptions is present.

STAND-BY Mode
If the UPS is in Stand-by mode, it is “inactive”. In Stand-by mode the Inverter is off and there is not Output power
but the UPS is not completely off: indeed the UPS recharges the batteries regularly and the graphic display is ON.
If the
OFF
button is pressed when the UPS is in Normal mode, the UPS switches in Stand-by mode.
If the UPS is in Stand-by mode and the AC Input line is removed from UPS, then the UPS switches completely off.
The Stand-by mode is identified by:
•
The graphic LCD panel shows the functioning during
Stand-by mode.

ECO Mode
It is possible to select the ECO mode to save energy and to increase the efficiency of the UPS.
The ECO mode uses the Bypass to feed the loads. The UPS will operate as in Bypass mode whenever the
Frequency/waveform/RMS value of AC Input line mains Voltage is within their tolerance limits. If the AC Input line
Voltage goes beyond these limits, the UPS switches into normal operation.
Please contact Technical Service for the instruction to enable the ECO mode; by default the ECO mode is disable.
ECO mode does not provide perfect stability in Frequency/waveform/RMS value of the
Output Voltage like in Normal mode. Thus, the use of this mode should be carefully
executed according to the level of protection required by the application.
The ECO mode is identified by:
•
The graphic LCD panel shows the functioning during
ECO mode (the “ECO” icon is ON).
