Grounding Recommendations
It is always recommended to establish the shortest possible
grounding path e.g. on steel hulls the ADU should be grounded
directly to the hull 2 . However, due to the fact that this is not
possible on e.g. fibreglass hulls (nor is it preferable on aluminium
hulls) a number of alternative grounding methods are suggested in
the following paragraphs.
2. Please note that the ADU ground connection is made at the same electrical
ground potential as the ACU.
