3.9 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.
