Auto-test (Only for Italy)
Inverter provides for Italian auto-test operation to verify the validity of functions about
over-voltage protection, under-voltage protection, over-frequency protection and
under-frequency protection.
After confirming “Auto test [Italy]” command, the inverter will perform protection
functions test automatically in turn. Finally the results will come out.
1. Press ENTER to enter general control screen.
2. Press ▼ to navigate arrow-pointer to “Set-param” and then press ENTER.
3. Press ► to move cursor to the right and press button ▼ to set password 1111.

5. Press ▼ to navigate arrow-pointer to “Sys-param” and then press ENTER.
6. Press ▼ to navigate arrow-pointer to “Auto test [Italy]” and then press ENTER.
Inverter will start to auto testing.
Vgrid-max: the maximum threshold of allowable grid voltage;
Vgrid-min: the minimum threshold of allowable grid voltage;
Fgrid-max: the maximum threshold of allowable grid frequency;
Fgrid-min: the minimum threshold of allowable grid frequency;
Vnorm: current grid voltage; Fnorm: current grid frequency;
Ttrip: time interval from current grid state exceeding allowable ranges to inverter
disconnecting from grid.
If four different values of “Ttrip” meet the corresponding standards, protective
functions of inverter are valid.
