6.1 Commissioning the Inverter
1. Check the following requirements before commissioning:
– Correct mounting and correct connection of the inverter.
– Correct layout of the line circuit breaker.
– Correct grounding of the small wind turbine system in accordance with the instructions of the
manufacturer.
– The rectifier and overvoltage protection (e.g. WindyBoyProtectionBox) are installed
between the small wind turbine system and the inverter.
– Unnecessary DC inputs are closed with the corresponding DC connectors and sealing plugs.

(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.
Start the self-test as described in the section 6.2”Self-Test in accordance with DK 5940,
Ed. 2.2 (Applies to Italy Only)” (page37). The test takes approx. 8minutes.
