– The rectifier and overvoltage protection (e.g. Windy Boy Protection Box) are installed

between the small wind turbine system and the inverter.

– Unused DC inputs are closed with the corresponding DC connectors and sealing plugs

2. Switch on the miniature circuit-breaker.
3. Commission the small wind turbine system in accordance with the instructions of the

manufacturer.

Self-test in accordance with DK 5940, Ed. 2.2 during initial start-up
(applies to Italy only)
The Italian DK 5940 standard prescribes that an inverter can only operate on the electricity
grid if 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 41). The test
takes approx. 8 minutes.
