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.
Circuit isolation
Appropriate circuit isolation is required for installations using
both AC and DC current:
• Always use isolating transformers or a separate power-inverter
to run PC’s, processors, displays and other sensitive electronic
instruments or devices.
• Always use an isolating transformer with Weather FAX audio
cables.
• Always use an isolated power supply when using a 3rd party
audio amplifier.
• Always use an RS232/NMEA converter with optical isolation
on the signal lines.
• Always make sure that PC’s or other sensitive electronic
devices have a dedicated power circuit.
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).

Making connections
Follow the steps below to connect network, transducer and
power cables to your unit.
1. Ensure that the vessel's power supply is switched off.
2. Ensure that the device being connected to the unit has
been installed in accordance with the installation instructions
supplied with that device.
3. Ensuring correct orientation push the cable connector fully
onto the corresponding connector on the unit.
4. Turn the locking collar clockwise to secure the cables.
