7.4 Starting the Self-Test (For Italy Only)
The self-test is only required for inverters to be commissioned in Italy. The Italian standard requires
that all inverters feeding into the utility grid are equipped with a self-test function in accordance with
CEI0-21. During the self-test, the inverter will consecutively check the reaction times for
overvoltage, undervoltage, maximum frequency and minimum frequency.
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 threeminutes.
Requirements:
☐ The country data set of the inverter must be set to CEI 0-21 internal.
Procedure:
1. Select the menu Device Configuration.
2. Select [Settings].
3. Select [Starting the Self-Test] in the subsequent context menu.
4. Observe the instructions shown in the dialog and save the report of the self-test, if necessary.
