Factory Configu-
ration
The inverter has been pre-configured in the factory and is ready for operation.
To change your inverter settings, please see "The Setup Menu" section in these instruc-
tions.
Start-up opera-
tion
Once the inverter has been connected to the solar modules (DC) and the public grid (AC),
turn the main switch to position - 1 -.
- As soon as the photovoltaic modules produce sufficient power, the Operating Status
LED lights up orange. The screen displays the startup phase. The orange LED indi-
cates that the feed-in mode of the inverter will begin shortly.
- After the automatic inverter start, the Operating Status LED lights up green.
- Provided that power continues to feed into the grid, the Operating Status LED will re-
main green to confirm that the inverter is functioning correctly.

Ground
If a solar module ground is being used, the status message 502 "Insulation value too low"
will be displayed after the inverter is turned on and upon completion of the startup phase.
NOTE! Regardless of whether bolts or fuses are used, do not operate the inverter
without fuse covers.
NOTE! To ensure the degree of protection at the inverter:
- Insert blanking plugs into all openings at the sealing insert in which there are
no cables
- If cables are run through the sealing insert, insert the remaining blanking
plugs in the recesses located on the outside

NOTE! If a solar module ground is used, the corresponding grounding mode must
be set in the 'Basic Service Menu' after the inverter is turned on.
A 5-character access code is required to access the 'Basic Service Menu.' This
access code will be provided by Fronius upon request.
