Fronius IG 15 - Manual (Page 74)

Service codes of service class 1 appear mostly only temporarily, their
cause lies in the public mains network.
The first reaction of your FRONIUS IG unit is to disconnect from the
mains. Subsequently the mains network will be checked for the duration
of the observation period stipulated. If after the end of this period no
further defect is identified, your FRONIUS IG unit resumes operating and
feeding power into the mains network.

ve designation, description, and repair measures.
