Routing of the Sensor Cable Routing of the Sensor Cable
The Sensor Cable should be connected to the Display Unit via the
terminal strip supplied.
•
The Sensor Cable should be routed to the Display Unit taking
care that potential tripping hazards are avoided.
•
The Sensor Cable should be tied at regular intervals to ensure
that the cable is not crushed or able to vibrate as this may affect
its performance.
•
The Sensor Cable should not be bent through tight radii ( less
than 4cm ).
•
Where the Sensor Cable passes through bulkheads or decking,
rubber grommets or the optional deck gland (ICS part number
2520.08) should be used to prevent chaffing.
Grounding Grounding Grounding Grounding
For some installations where local interference is thought to be
limiting receiver performance, it may be necessary to ground the
screen of the antenna cable.
Connect the screen of the interconnecting cable from the connecting
block to a good electrical ground. This can either be a specially
installed ground plate, or the keel bolts on a non-encapsulated keel.
If electrical isolation is to be maintained then this should be done via
a 0.1uF 50V capacitor.
If in doubt consult your dealer.
