ECO mode
If ECO mode is selected, all power switches and the battery switches are closed except for the maintenance bypass switch,
and the system prefers to put the load on the bypass, to achieve the aim of energy-saving. When the bypass supply is within
the range of normal frequency and normal voltage (adjustable), the load is powered by the bypass, with the inverter on
stand-by; when the voltage and/or frequency of the bypass supply are beyond the pre-defined and adjustable limits, the
system will transfer to the inverter output, and the transfer time for switching from bypass to inverter is less than 2 ms
(uninterrupted) and less than 5 ms (interrupted). In this mode, the system can normally charge the battery.

If ECO mode is required, adjust corresponding parameters through the touch screen.
The operation method of ECO mode is the same as described in Chapter 5 UPS Operation Introduction. However, in normal
mode, the load is powered by the bypass, the inverter indicator is flashing, and the touch screen displays 'Bypass mode'.
