Class 1
(continued)
Class 2 service codes can only occur in connection with the optional overvoltage/under-
voltage relay.
Class 2 service codes are also related to the mains parameters. Therefore, some of the
testing methods overlap with those for service class 1. The FRONIUS IG will react in
exactly the same way as with class 1 service codes.
