5.4 Transferring to Bypass Mode

Before shutting down the inverter, ensure that the bypass is normal. If the bypass
is not normal, after the inverter is shut down, the UPS supplies no power, and the
loads shut down.
Shut down the UPS inverter. Shut down the inverter on the LCD or WebUI, and the
UPS transfers to bypass mode.

If the inverter is shut down when the input voltage or frequency exceeds the specified
threshold, the UPS supplies no power, and the loads shut down.
The UPS is set to non-ECO mode by default. Set the UPS to ECO mode when
energy saving is required.
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.
