B.5 Alternative grounding for fibre glass hulls
B.5.1 Grounding the ACU
The ACU should preferably be grounded with the short ADU cable and a grounding kit
(available from Thrane & Thrane). Further, the ACU must be grounded at its grounding
stud in order to ensure a proper grounding if the short ADU cable is disconnected.
The ground connection must be established at a dedicated RF ground (either
capacitive or electrical coupled).
B.5.2 Grounding the ADU
If the mounting base of the ADU is electrically connected to any other ground potential
than the ACU (e.g. Lightning Ground), the ADU must be isolated at its mounting bolts
by means of shoulder bushings and washers - see section B.6.3.
However, a ground connection must be established via one of the mounting bolts
using a separate ground cable. The ground cable must be routed parallel and in close
proximity to the shielded coax cable hence connecting the ADU to the ACU Grounding
kit. A heavy gauge wire with tinned strands (min. 6 mm
2
) can be used for this purpose.
Importan
Bear in mind that the ADU ground connection is to
be made at the
same electrical ground potential as
the ACU (see Grounding the ADU ).
