Self test in accordance with DK 5940, Ed. 2.2 for initial commissioning
(applies to Italy only)
The Italian DK 5940 standard prescribes that an inverter can only operate on the public
grid after the disconnection times for overvoltage, undervoltage, minimum frequency and
maximum frequency have been checked.
If you have configured the DK5940E2.2 country data set, then start the self-test as
described in section 6.3 ”Self-Test in accordance with DK 5940, Ed. 2.2 (Applies to Italy
Only)” (page 55). The test takes approx. 3 minutes.
