Grounding the Radar
The radar (and voltage converter, if applicable) must be connected to the appropriate type of ground using a
3.31 mm² (12 AWG) copper wire (not included).
1
Route a 3.31 mm² (12 AWG) copper wire to a water ground location and to the radar pedestal.
2
Connect the wire to the ground connector on the pedestal (
) using the pre-installed crimp connector.
3
Coat the ground screw and crimp connector with marine sealant.
4
Connect the other end of the wire to the water ground location on the boat, and coat the connection with
marine sealant.
5
Select an option:
•
If your radar was not packaged with a voltage converter, no further grounding is necessary.
•
If your radar was packaged with a voltage converter, proceed to step 6.
6
Route a different 3.31 mm² (12 AWG) copper wire to water ground location and to the voltage converter.
7
Loosen a screw on one corner of the voltage converter and secure the copper wire to the screw.
8
Coat the screw and wire on the voltage converter with marine sealant.
9
Connect the other end of the wire to the RF ground location on the boat, and coat the connection with marine
sealant.
