DC power connection
Power is supplied to the scanner via the display unit; the power cable is supplied
with the display unit, refer to your display unit Owner’s Handbook for details
on connecting power. However, you should be aware of the following.
The DC system should be either:
with the display unit, refer to your display unit Owner’s Handbook for details
on connecting power. However, you should be aware of the following.
The DC system should be either:
• Negative grounded, with the negative battery terminal connected to the
ship’s ground.
• Floating, with neither battery terminal connected to the ship’s ground.
CAUTION:
This radar is not intended for use on “positive” ground vessels.
The power cable Earth screen connections must be connected to the ship’s
ground.

Grounding the radar system
It is important that an effective RF ground is connected to the radar system. You
must ground the radar by connecting the drain wire (screen) of the Power/
NMEA Input cable to the nearest ground point of the ship’s RF ground system.
Refer to your display unit Owner’s Handbook for details.
Note: Use only this ground connection.

Refer to your display unit Owner’s Handbook for details.
Note: Use only this ground connection.
Power Connections
The power connection to the radar should be made at either the output of the
battery isolator switch, or at a DC power distribution panel. Raytheon
recommends that power is fed directly to the radar via its own dedicated cable
system and MUST be protected by a thermal circuit breaker or fuse, fitted close
to the power connection. Refer to the table below for isolator switch, circuit
breaker or fuse value ratings. Check all terminal connections are clean.

CAUTION:
If you do not have a thermal circuit breaker or fuse in your power circuit,
e.g. fitted to the DC distribution panel, you MUST fit an in-line breaker or
fuse to the positive (red) lead of the power cable.
