1.5 Radar Unit Installation 17
• The device should be mounted away from heat sources, such as smoke stacks and
lights.
• The device should be mounted at a different level than horizontal spreaders and mast
crosstrees.
• To avoid interference with a magnetic compass, the device should not be mounted
closer to a compass than the compass-safe distance value listed in the product
specifications.
• Other electronics and cables should be mounted more than 2 m (6.5 ft) from the radar
beam path.
• GPS antennas should be either above or below the radar beam path.
•
The device should be mounted at least 1 m (40 in) from any transmitting equipment.
• The device should be mounted at least 1 m (40 in) from cables carrying radio signals
such as VHF radios, cables, and antennas.
• The device should be mounted at least 2 m (6.5 ft) from Single Side Band (SSB) radios.
1.5.3 Cable Considerations
It may be necessary to drill 32 mm (1¼ in) holes for routing the power or network cables.
• When routing multiple cables through the same hole, you must route the network
cable before the power and ground cables because of the size of the network
connector.
• You must apply marine sealant to the hole after the cables are in place to ensure a
waterproof seal.
If the routing hole must be made in a visible location, decorative cable grommets can be
purchased from Garmin or a Garmin dealer (optional).
• If needed, you can trim the grommet to enable you to route multiple cables through
the same hole.
• The optional grommet does NOT provide a waterproof seal. You must apply marine
sealant to the grommet after the cables are in place to ensure a waterproof seal.
When installing the cables, you should observe these considerations:
• Cutting the Garmin Marine Network cable is not recommended, but a field install
kit can be purchased from Garmin or a Garmin dealer if cutting the network cable is
necessary.
• To ensure safety, appropriate tie-wraps, fasteners, and sealant should be used to
secure the cable along the route and through any bulkheads or the deck.
• You should not run cables near moving objects and high-heat sources, or through
doorways and bilges.
• To avoid interference with other equipment, you should not run network and power
cables next to or parallel to other cables, such as radio antenna lines or power cables.
If this is not possible, the cables should be shielded with metal conduit or a form of
EMI shielding.
• You should install the power cable as close to the battery source as possible.
• If it is necessary to extend the cable, you must use the appropriate wire gauge.
• Incorrectly extended runs of cable may cause the radar to malfunction due to
insufficient power transmission.
