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.
