Claims

c1 drafted · lead fronius-symo-ul-emanual-status-codes

reports

c2 drafted · lead DC link fault

review note: support check: partial - Intermediate circuit voltage relay switched off is related to DC link but 'fault' is not exactly stated; reasonably implied.

has_event_class

c3 drafted · lead Fault (device stops or needs intervention)

review note: support check: partial - Class 4 generic text doesn't explicitly link 479 to class 4; device attempts auto reconnect, fault only loosely implied.

has_recovery

c4 drafted · lead Auto-reset (clears by itself)

Inverter reconnects automatically; service technician if the code persists.

mitigated_by

c5 drafted · lead Contact manufacturer service

Only if the code persists.

applies_to

c6 drafted · lead Fronius Symo
