as power is being fed into the mains

NOTE! A message will appear if, for instance, there is an insulation fault even if
it does not have any adverse effect on the FRONIUS IG’s operation. However,
our advice is that, for safety reasons, the insulation fault is rectified as soon as
possible.
A status message is displayed. If a message such as “502”! is displayed (see chapter
entitled “Status diagnosis and repair”), the status concerned should be rectified and the
“Enter” key then pressed in confirmation.

(see chapter entitled “The Setup Menu”)
