Raymarine AIS 350 Installation Instructions Manual page 30

• 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).
