3.8 General location requirements

Important considerations when choosing a suitable
location for your product.
This product is suitable for mounting above or below
decks.
The product should be mounted where it will be:
• protected from physical damage and excessive
vibration.
• well ventilated and away from heat sources.
• away from any potential ignition source such as an
engine room, near fuel tanks or a gas locker.
When choosing a location for the product,
consider the following points to ensure reliable and
trouble-free operation:
• Access — there must be sufficient space to
enable cable connections to the product, avoiding
tight bends in the cable.
• Diagnostics — the product must be mounted in
a location where the diagnostics LED is easily
visible.
Note: Not all products include a diagnostics
LED. Refer to the Chapter 6 System checks
and troubleshooting for more information.
• Electrical interference — the product should be
mounted far enough away from any equipment
that may cause interference such as motors,
generators and radio transmitters / receivers.
• Magnetic compass — refer to the Compass
safe distance section in this document for advice
on maintaining a suitable distance between this
product and any compasses on your vessel.
• Power — to keep cable runs to a minimum, the
product must be located as close as possible to
the vessel's dc power supply.
• Mounting surface — ensure the product is
adequately supported on a secure surface. Refer
to the weight information provided in the Technical
specification for this product and ensure that the
intended mounting surface is suitable for bearing
the product weight. Do NOT mount units or cut
holes in places which may damage the structure
of the vessel.

Cable routing requirements

Consider the following before installing the system
cables:
• You will need to attach power, transducer and
network cables to the unit.
• The transducer cable should only be extended
where the sonar module cannot be installed
close enough to the transducer to allow a direct
connection.
• All cables should be adequately secured,
protected from physical damage, and protected
from exposure to heat.
• Avoid sharp bends in cables.
• Use a watertight feed-through wherever a
cable passes through an exposed bulkhead or
deckhead.
• Secure cables in place using tie-wraps or lacing
twine. Coil any extra cable and tie it out of the way.
• Do NOT run cables through bilges or doorways, or
close to moving or hot objects.
• Do NOT run cables near to engines or fluorescent
lights.
Always route data cables as far away as possible
from:
• other equipment and cables,
• high current carrying ac and dc power lines,
• antennas.

Compass safe distance

To prevent potential interference with the vessel's
magnetic compasses, ensure an adequate distance
is maintained from the product.
When choosing a suitable location for the product
you should aim to maintain the maximum possible
distance from any compasses. Typically this distance
should be at least 1 m (3 ft) in all directions. However
for some smaller vessels it may not be possible to
locate the product this far away from a compass. In
this situation, when choosing the installation location
for your product, ensure that the compass is not
affected by the product when it is in a powered state.
