Class 2 - Fronius IG 2000 Operating Instructions Manual

Class 2

Definition of service class: First digit in code represents the category.
Service codes of service class 2 are typically temporary. Their cause lies
in the grid.
The first reaction of your FRONIUS IG unit is to disconnect from the grid.
Subsequently, the grid will be checked for the duration of the observation
period stipulated. If after the end of this period no further defect is identi-
fied, your FRONIUS IG unit resumes operating and feeding power into the
grid.
The following table lists a number of service codes with their respective
designation, description, and repair measures.
