3. Test Route the Cables
Using the information in this section, test route the cables from the planned mounting location to the control
head or Ethernet Switch location and the power source. Cables must be routed correctly to maximize
performance and prolong cable life. See
Connect to Power and Ethernet
for more information.
CIRCUIT ISOLATION WARNING!
Proper circuit isolation is required for installations using both
AC and DC current. If you are installing a 3rd party product that utilizes AC current, contact a qualified
marine installer for assistance.
CAUTION!
Do NOT mount the cables where the connectors could be submerged in water or flooded. If
cables are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the
connectors to prevent corrosion. Dielectric grease can be purchased separately from a general hardware or
automotive store.
Avoid Cable Bending
Do NOT bend cables excessively.
Wherever possible, ensure a minimum
bend radius of 4" (100 mm).
Strain Relief
Ensure adequate strain relief is provided. Protect connectors from strain and ensure they will not pull out
under extreme sea conditions.
Cable Protection
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.
• Do NOT run cables near to engines or fluorescent lights.
• Where a cable passes through an exposed bulkhead or deckhead, use a suitable watertight feed-
through.
• Route data cables away from other equipment and cables, high current carrying AC and DC power
lines, and antennae.
• Secure cables in place using cable ties or lacing twine. Coil any extra cable and tie it out of the way.
•
Cable Shielding:
Ensure that all data cables are properly shielded and that the cable shielding is
intact (e.g. hasn’t been scraped off by being squeezed through a tight area).
