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

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.
