Class 2 - Fronius IG 15 Operating Instructions Manual

Class 2

Service class 2 codes can only arise in connection with the ENS option.
Class 2 service codes are also related to the parameters of the mains
network. Some of the checking procedures therefore overlap with those of
service class 1. Your FRONIUS IG unwill react in the same way as in the
case of service codes in service class 1.
