3.3.3 Grounding the ADU
The ADU must be grounded using the mounting bolts. If the ADU cannot or should not
be electrically connected directly to the mounting surface, you can use a separate
grounding cable to make the connection between the ADU and the common ground to
which the ACU is also connected. If grounding to the ship ground is impossible, for
example if you have a fibre glass hull, see
Alternative grounding for fibre glass hulls on
page B-8.
To obtain a good ground connection, the metal underneath the head of at least one
bolt must be clean of insulating protective coating and a serrated washer should be
used. After tightening the bolts we recommend that you seal the area suitably in order
to avoid corrosion of the grounding point. Use stainless steel bolts and washers.
Optimum grounding is achieved by connecting the ground wire to the bolt marked in
Figure 3-20.
For further information on grounding and RF protection see Grounding and RF
protection on page B-1.
