Service codes in service class 1 generally only arise momentarily, and are caused by the
public mains network.
The initial response of the FRONIUS IG in this case is to disconnect itself from the
mains. The mains is subsequently checked for the stipulated monitoring period. If no
further problem has been detected by the end of this period, then the FRONIUS IG will
resume feeding power into the mains.
A list of service codes, associated designations, descriptions and corrective actions can
be found in the table below.
