7.1 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 FLIR.
• Ensure that any non-FLIR 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.
7.2 Cable routing
Cables must be routed correctly, to maximize performance and prolong
cable life.
• Do NOT bend cables excessively. Wherever possible, ensure a minimum
bend diameter (Ø) of 200 mm (7.87 in) / minimum bend radius (R) of
100 mm (3.94 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 cable clips or cable ties. Coil any excess
cable and tie it out of the way.
• Where a cable passes through an exposed bulkhead or deckhead, use a
suitable watertight feed-through.
Cables and connections — General information
• 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.
7.3 Strain relief
Use adequate strain relief for cabling to ensure that connectors are protected
from strain and will not pull out under extreme sea conditions.
7.4 Cable shielding
Ensure that cable shielding is not damaged during installation and that all
cables are properly shielded.
7.5 Suppression ferrites
• Cables may be pre-fitted or supplied with suppression ferrites. These are
important for correct EMC performance. If ferrites are supplied separately
to the cables (i.e. not pre-fitted), you must fit the supplied ferrites, using
the supplied instructions.
• If a ferrite has to be removed for any purpose (e.g. installation or
maintenance), it must be replaced in the original position before the
product is used.
• Use only ferrites of the correct type, supplied by the manufacturer or its
authorized dealers.
• Where an installation requires multiple ferrites to be added to a cable,
additional cable clips should be used to prevent stress on the connectors
due to the extra weight of the cable.
• If your camera installation requires long cable runs, you may need to fit
additional ferrites to maintain acceptable EMC performance.
