6.3 Self‑test in Accordance with DK 5940, Ed. 2.2

(Applies to Italy Only)

6.3.1 Starting the Self‑Test by Tapping
You can start testing the disconnection times by tapping on the enclosure lid. A prerequisite here is
that the country configuration of the inverter has been set to Italy (IT/DK5940) or "trimmed".
Proceed as follows for checking the disconnection times:
1. Connect the PV array to the inverter. The inverter can only initialize if the PV array produces
enough power. It is therefore not possible to test the disconnection times at night.
2. Connect the inverter on the AC side. For this, you have to establish the AC connection
(AC plug or direct connection) and/or switch on the miniature circuit‑breaker.
3. The inverter is now in the initialization phase, i.e. all 3 LEDs are lit at the same time.
Start the self‑test immediately after all 3 LEDs have gone out by tapping on the display of the
inverter.
4. The question of whether you would like to start the
test sequence appears in the display. Tap on the
display again within 30 seconds to confirm the
question.
Once you have started the test sequence, the inverter checks the disconnection times for overvoltage,
undervoltage, maximum frequency and minimum frequency one after the other. During the tests, the
inverter shows the values in the display which are described in section 6.3.2 "Completion of the
Self‑test" (page 51).
