Installation of the ADU
3-22 Chapter 3: Installation 98-146706-A
3.3.3 To ground the ADU
The ADU must be grounded using the mounting bolts.
To ground the ADU do as follows:
1. Clean the metal underneath the head of
at least
one bolt of insulating protective
coating and use a serrated washer to obtain a good ground connection
2. Tighten the bolts. Use stainless steel bolts and washers.
3. Seal the area suitably to avoid corrosion of the grounding point (recommended).
For optimum grounding connect the ground wire to the bolt marked in the figure below.
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 ground for fibre glass
hulls on page B-9.
For further information on grounding and RF protection see the appendix Ground and RF
protection
on page B-1.
