Maximum frequency
In the 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 is reduced step by step until the
disconnection threshold is reached and the inverter
disconnects from the electricity grid.
Once the inverter has disconnected from the electricity grid, the display alternates between the
following values:
• Disconnection value,
• Calibration value,
• Reaction time,
• Current power frequency.
