Grid connec- Your FRONIUS IG unit needs to be connected to the DC/AC Disconnect
tion Switches and to the equipment grounding according to the enclosed
diagrams.
Your FRONIUS IG is equipped with a PV and Utility disconnect switch that
switches AC and DC separately.
Depending on the installation, an external AC and/or DC disconnect may
be required if the inverter is installed in a location not easily accessible to
utility or fire personnel. Consult local authorities for additional information.
The FRONIUS IG comes from the factory pre-configured for grid connec-
tion with neutral. The FRONIUS IG may be reconfigured for grids without
neutral by setting the jumper on the PC-board as shown in the figure.
Important! Open the connection area as explained in the section „Con-
nection".
ment factor for crystalline silicon modules, or use the manufacturer's
specified voltage coefficient.
WARNING! In order to ensure the best possible operation of the grid
monitoring system, it is important to make sure that there is minimal
resistance in the lines to the connection point. The AC conductor
resistance between the FRONIUS IG unit and the building's distribu-
tion panel should not exceed 0.5 Ohm.
NOTE! The neutral conductor is not bonded to ground internally.
