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 power
distribution grid after the disconnection times for overvoltage, undervoltage, minimum
frequency and maximum frequency have been checked.
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 51). The test takes approx. 8 minutes.
