7.1 Commissioning the Inverter
1. Check that the inverter is firmly mounted on the wall and secured against being lifted out
(see section 4.3"Mounting the Inverter with the Wall Mounting Bracket" (page17)).
2. Check for correct country configuration
(see section 5.3.2"Checking the Country Standard" (page24)).
3. Check that the AC cables are connected correctly
(see section 6.3"Connection to the Power Distribution Grid (AC)" (page36)).
4. Check that the DC cables (PV strings) are connected correctly
(see section 6.4"Connecting the PV Array (DC)" (page42)).
5. Close up unnecessary DC inputs with the DC connectors and sealing plugs
(see section 6.4.4"Connecting the PV Array (DC)" (page46))..
6. Check whether all enclosure openings are closed.
7. Check whether the enclosure lid is firmly screwed in place.
8. Check that the Quick Module is connected correctly.
9. Firmly connect the Electronic Solar Switch.
10. Check that you have the correct type of miniature circuit‑breaker.
11. Switch on the miniature circuit‑breaker.
12. If a multi‑function relay is connected, switch on the multi‑function relay supply voltage.
Self‑test in accordance with ENEL guideline during initial start‑up (only for Italy)
The Italian 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.
If you have configured the Enel‑GUIDA country data set, start the self‑test as described in
section 7.3"Self‑Test in Accordance with ENEL Guideline, Ed. 1.1 (Applies to Italy Only)"
(page52). The test takes approx. 3 minutes.
