F.2 Grounding Recommendations
F.2.1
Grounding the ACU
The ACU should be grounded to the ship/hull. For this purpose you
may use a short ADU cable and a grounding kit. Further, the ACU
must be grounded at its grounding stud in order to ensure proper
grounding if the short ADU cable is disconnected. For further
information, see Grounding the terminal on page 2-33.
If you use the Extended cable support, make the ground
connections through the cable support. You may need to extend the
ground plane using copper foil, see the following section.
F.2.1.1
Extending the ground plane
In some cases it may not be possible to access the hull and at the
same time place the ACU in a suitable place. A way to insure good
grounding and at the same time make it possible to ground the coax
cable - is to extend the ship ground plane by means of copper foil.
The maximum length of the foil is determined by the width of the
foil:
Copper foil 5 cm wide: Max 50 cm
Copper foil 10 cm wide: Max 100 cm
Copper foil 20 cm wide: Max 200 cm
Note
The foil must be at least 0.1 mm thick.
Connect the foil to the hull by plenty of screws or hard–soldering.
Run the foil past the place where the short ADU cable is to be
