If the grid type is set to 240 Vac without neutral, then the display will be looked as the figure shown below.

And then three (3) seconds later, LCD will show the voltage setting for the inverter to drop the grid connection. The settings
of the Vl-nH and its clearing time will be displayed. The Vl-nH setting is the phase-to-neutral (rms) high threshold voltage
setting at which point the inverter disconnects its output from the AC power grid when abnormally high phase-to-neutral AC
voltage is detected. After the setting of the Vl-nH is displayed, the setting of the Vl-nL will be displayed for 3 seconds.

Three (3) seconds later, it displays the setting of the VacH which is the phase-to-phase (rms) high threshold voltage setting at
which point the inverter disconnects itself from the grid when abnormally high phase-to-phase AC voltage is detected. Also,
the setting of the clearing time which is the total duration of time to disconnect the output from the AC grid is displayed. The
clearing time is the summation of the de-bounce time and the hardware delay time. This delay is necessary to avoid nuisance
trips. After the settings of the VacH and its clearing time, the settings of the VacL and its clearing time will be displayed for
three (3) seconds. The display Vl-nH/Vl-nL is only for 208/240 with neutral setting, VacH/VasL is only for 240 or 208
without neutral, they would not display at the same time.

Then the high and low threshold settings of the AC frequency and the clearing time will be shown for three (3) seconds. When
the AC frequency reaches the high or low threshold setting, the inverter will disconnect its output from the AC grid.
