3.1.7 Green Mode _ Single Input_ Single Unit
To activate green mode, please refer to 6.2.7 Green Mode Start-up Procedures, 7.6 Main
Screen and 7.10.2 Mode Setting.
Green mode is the same as online mode, but the difference is that the system will automatically
detect the output status (i.e. total load capacity %) to decide which specific power modules
should be fully powered on or idle in order to achieve higher efficiency of the UPS. For the
green mode diagram, please see Figure 3-9. During green mode, the UPS’s tri-color LED
illuminates green and the text ‘Green’ appears in the upper right corner of the screen.
