Maximum frequency
In a third step, the inverter tests the maximum frequency.
During the test sequence, the frequency limit applied is
shown in the display of the inverter.
The frequency limit is reduced successively until the shut-
down threshold is reached and the inverter disconnects from the power distribution grid.
Once the inverter has disconnected from the power distribution grid, the display successively shows
the following values one after the other:
• Disconnection value,
• Calibration value,
• Reaction timel,
• Current grid frequency.
