1.
Strip away approximately 0.4" (10 mm) of the shielding at the end of the power cable, and
then identify the positive wire and the negative wire.
2.
Unscrew the small holding screw from the positive power cable input connector (identified
by the + sign) on the radar processor.
3.
Insert the bare ends of the positive wire into the positive power cable input connector to
make a connection.
4.
Tighten the small holding screw to hold the positive wire in place. Gently pull on the
positive wire to ensure that it is secured.
5.
Repeat this process to connect the negative wire to the negative power cable input
connector (identified by the – sign).

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.

Checklist
When you've finished the wiring, visually check that:
each component is securely mounted and able to withstand rough sea conditions.
an open array scanner has the rotating boom securely bolted onto the scanner base unit.
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 set up the radar with the Northstar system that you're using.
