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

disconnection threshold is reached and the inverter

disconnects from the mains.

Once the inverter has disconnected from the mains, the display successively shows the following

values one after the other:

•Disconnection value,

•Calibration value,

•Reaction time,

• Current power frequency.
