Simrad MN000802A-G manual Connect the ground wire, Radar system checklist

6.5 Connect the ground wire

The radar processor has a Chassis Earth connection stud located on the far right hand side of the unit. The Chassis Earth is DC isolated from power (–ve) to eliminate the risk of galvanic corrosion.

If you are installing the radar processor on a vessel with a metal hull, connect the radar processor Chassis Earth to the hull at the closest possible location, using 12 AWG wire (or thicker):

The eyelets must be crimped or soldered at both locations (A) and the method of connection to the vessel's hull is shown at (B).

If you are installing the radar processor on a vessel with a non-metallic hull, connect the radar processor Chassis Earth to the vessel's ground network. If a vessel's ground network is not available, leave the radar processor Chassis Earth unconnected.

6.6 Radar system checklist

When you've finished the wiring, visually check that:

•each component is securely mounted and able to withstand rough sea conditions.

•all the cables are correctly installed.

•any cable shield mesh is correctly configured.

•all cable entry points are watertight.

•water can't leak into the scanner.

Now you're ready to interface to your choice of display head.
