4.1 General cabling guidance
Cable types and length
It is important to use cables of the appropriate type
and length
• Unless otherwise stated use only standard cables
of the correct type, supplied by Raymarine.
• Ensure that any non-Raymarine cables are of the
correct quality and gauge. For example, longer
power cable runs may require larger wire gauges
to minimize voltage drop along the run.
Routing cables
Cables must be routed correctly, to maximize
performance and prolong cable life.
• Do NOT bend cables excessively. Wherever
possible, ensure a minimum bend diameter of 200
mm (8 in) / minimum bend radius of 100 mm (4 in).
100 mm (4 in)
200 mm (8 in)
• Protect all cables from physical damage and
exposure to heat. Use trunking or conduit where
possible. Do NOT run cables through bilges or
doorways, or close to moving or hot objects.
• Secure cables in place using tie-wraps or lacing
twine. Coil any extra cable and tie it out of the way.
• Where a cable passes through an exposed
bulkhead or deckhead, use a suitable watertight
feed-through.
• 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,
• antennae.
Strain relief
Ensure adequate strain relief is provided. Protect
connectors from strain and ensure they will not pull
out under extreme sea conditions.
Cable shielding
Ensure that all data cables are properly shielded
that the cable shielding is intact (e.g. hasn’t been
scraped off by being squeezed through a tight area).

product loading
The number of products that can be connected
to a
SeaTalk
ng
backbone depends on the power
consumption of each product and the physical overall
length of the backbone.
SeaTalk
ng
products have a Load Equivalency
Number (LEN), which indicates the product’s power
consumption. The LEN for each product can be
found in the product’s Technical Specification.
