Log in to the ECC800-Pro_2 WebUI as an administrator.
Choose Maintenance > Configuration File.
Specify Configuration file decryption password.
Click Select File on the right of Import configuration file.
Select the configuration file to be imported, and click Upload.
Only the three-phase four-wire 380 V AC/400 V AC/415 V AC (line voltage)
model supports the S-ECO mode.
The system is working in inverter mode.
By default, the system works in a mode other than S-ECO. To enable the
system to work in S-ECO mode, set the working mode to S-ECO mode.
In S-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 S-ECO mode which ensures
higher efficiency.
To avoid frequent transfers between S-ECO mode and normal mode, do not
set S-ECO mode when the bypass input is unstable or is sensitive to load
changes.
When the load rate is less than 10%, the S-ECO mode does not present
obvious advantages so the S-ECO mode is not recommended.
Before setting S-ECO mode, ensure that the bypass is working properly.
In S-ECO mode, the UPS automatically selects the VFD, VI, or VFI working
mode in real time based on the combination of physical parameters such as
the load rate, load current THDi, load power factor, and real-time input
voltage waveform.
– S-ECO mode VFI: When the input voltage is of poor quality and fluctuates
greatly (the voltage and frequency exceed the specifications, the power
factor is less than 0.5, or the load rate is less than 10%), the UPS
automatically transfers to normal mode to avoid supplying power of poor
waveforms to loads. The UPS monitors the input voltage waveform in
real time. When the input voltage becomes normal, the UPS goes back to
the S-ECO mode or other power supply modes.
