Self-test in accordance with DK 5940, Ed. 2.2 for initial commissioning
(applies to Italy only)
The Italian standard DK 5940 requires that an inverter may only be operated on the power
distribution grid if the disconnection times for overvoltage, undervoltage, minimum
frequency and maximum frequency have been tested.
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 50). The test takes approx. 8 minutes.
