The self-test changes the upper and lower disconnection values for each protective function on a
linear basis for frequency monitoring and voltage monitoring. As soon as the measured value
exceeds the permitted disconnection threshold, the inverter disconnects from the utility grid. In this
way, the inverter determines the reaction time and checks itself.
After the self-test has been completed, the inverter automatically switches back to feed-in operation,
resets the original disconnection conditions and connects to the utility grid. The test takes
approximately threeminutes.
Requirements:
☐ The country data set of the inverter must be set to CEI 0-21 internal or DEWA2016
internal.
Procedure:
1. Select the menu Device Configuration.
2. Select [Settings].
3. Select [Starting the Self-Test] in the subsequent context menu.
4. Follow the instructions appearing in the dialog and save the report of the self-test where
necessary.
