7.4 Transferring to Bypass Mode Manually

Before you shut down the inverter, ensure that the bypass is normal. If the bypass
is abnormal, after you shut down the inverter, the UPS supplies no power, and the
loads are powered off.
Shut down the inverter on the LCD or WebUI. The UPS automatically transfers to
bypass mode.

If you shut down the inverter when the bypass input voltage or frequency exceeds the
specified threshold, the UPS supplies no power, and the loads are powered off.
The UPS is set to non-ECO mode by default. Set the UPS to ECO mode when
it is required.
In ECO mode, the bypass takes priority over the inverter in supplying power. If
the bypass fails, the UPS transfers to inverter mode.
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.
