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. Code

Excessive mains voltage
As soon as the mains voltage, after detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network
Check mains voltage
As soon as the mains voltage, after a detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network
Check mains voltage
As soon as the mains frequency, after a detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network

Imbalance of mains network impedance
As soon as the mains impedance after a detailed check, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network
Imbalance reaction can be only short termed
206
Absolute reading of mains impedance too high
As soon as the mains impedance after detailed checking, has returned to the admissible range, your FRONIUS IG resumes feeding power into the mains network
Check in-house line cable cross section
