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 check of the disconnection times by tapping on the enclosure lid. The prerequisite
for this is that the inverter country setting 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 initialise once the
small wind turbine system is producing enough power.
2. Connect the inverter on the AC side. To do this, you have to make the AC connection
(AC plug or direct connection) and switch on the circuit-breaker of the grid feed cable
(fuse or miniature circuit-breaker).
3. The inverter is now in the initialisation phase, i.e. all three LEDs are simultaneously on.
Start the self-test immediately after all three LEDs have gone out by tapping on the display of
the inverter.
4. The display queries whether you would like to start
the test sequence. Tap on the display again within
30 seconds to confirm.
Once you have started the test sequence, the inverter
successively checks the disconnection times for overvoltage, undervoltage, maximum frequency and
minimum frequency. During the tests, the values described in Section 6.3.2 "Completion of the Self-
test" (page 42) appear in the display.
