Figure 4-7 ECO specifications
Step 3 (Optional) If you set ECO mode when the UPS is in bypass mode, manually start
the UPS inverter.
After the inverter is started, the UPS still works in bypass mode, and the inverter is
on standby. When the bypass is abnormal, the UPS transfers to inverter mode
immediately. If the inverter is not started, the UPS stops supplying power when
the bypass is abnormal, and the system may power off.

Both a single UPS and a parallel system support ECO mode which ensures a
higher efficiency.
To avoid frequent transfers between ECO mode and normal mode, do not set
ECO mode when the bypass input is unstable or is sensitive to load changes.
ECO mode is not recommended when the load is less than 10%.
Before setting ECO mode, ensure that the bypass is working properly.
NO TE
If the ECO mode is set when the UPS works in inverter mode, the UPS transfers to the ECO
mode 4 minutes after the setting is complete and the conditions are met.
