Fronius 10.0-1 Serviceanleitung Seite 105

Code Description
481 Recerbo has old software
version
482 Inverter switched off during
commissioning
483 Set DC2 fixed voltage out-
side of the permitted MPP
range
484–485 Error during data transfer
Service Class 5–6
Class 5–6 status codes generally do not impair grid power feed operation, but can result
in limitations to it. They will be displayed until the status code is acknowledged by pressing
a key (the inverter, however, continues working normally in the background).
