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 the test of the disconnection times by tapping on the enclosure lid. The requirement for
this 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 small wind turbine system to the inverter. The inverter can only initialize once the
small wind turbine system is producing enough power. It is therefore not possible to test the
disconnection time if there is no wind.
2. Connect the inverter on the AC side. To do this, you must execute the AC connection
(AC plug or direct connection) and/or switch on the miniature circuit-breaker on the grid supply
line (fuse and circuit-breaker).
3. The inverter is now in the startup phase, i.e. all 3 LEDs are simultaneously lit.
Start the self-test immediately after all 3 LEDS have gone out by tapping on the display of the
inverter.
4. The display will ask whether you would like to start
the test sequence. Confirm by tapping on the
display again within 30 seconds.
Once you have started the test sequence, the inverter will consecutively check the disconnection times
for overvoltage, undervoltage, maximum frequency and minimum frequency. During the test, the
inverter will display the values described in Section 6.3.2 "Completion of the Self-test" (page 51).
