In ECO mode, the bypass takes priority over the inverter in supplying power. If the
bypass is disconnected, the UPS transfers to normal mode.
To avoid frequent transfer between ECO mode and normal mode, do not set the 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 transferring the UPS to ECO mode, ensure that the bypass module works
properly.

Step 3
If you set ECO mode in bypass mode, manually start the UPS inverter.
After the inverter starts, the UPS still works in bypass mode and the inverter is on standby. If
the bypass is not normal, the inverter supplies power immediately. If the inverter is not started,
the UPS may be disconnected.
