mode to ECO. The information indicating that the UPS works in ECO mode is
displayed on the LCD.

Figure 4-7 ECO parameters
Step 3 (Optional) 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.

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 fails, the UPS transfers to inverter mode.
Both a single UPS and the parallel system support the ECO mode for higher
efficiency.
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 setting ECO mode, ensure that the bypass is working properly.
