2.3 System connections
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.
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.

Note: Use only this ground connection.
Radome systems
The Radome radar system is intended for use on ships’ DC power systems
operating in the 10.7 to 32 V dc range (12 V and 24 V systems, not 32 V
systems). The connections should be made at a DC power distribution panel,
through an isolation switch or circuit breaker that is fused or trips at not greater
than 10 A. Check that all connection terminals are clean.

CAUTION:
If you do not have a breaker in your power circuit, you must fit an in-line
6.3 A quick-blow fuse to the positive (red) lead of the power cable.

Open array systems
The 5S 48" open array radar system is intended for use on ships’ DC power
systems operating in the 10.7 to 44 V DC range (that is, 12 V, 24 V and 32 V
systems). Raytheon recommends that power is fed directly from the output of
the battery isolator switch via its own dedicated cable system.

CAUTION
The display unit does not include a fuse for scanner power so an in-line
fuse or circuit breaker, rated at 20 A for 12 V systems or 10 A for 24 V and
32 V systems, MUST be included in the positive supply lead (red) of the
power cable.
