1.5.4 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 first 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 device to malfunction due to
insufficient power transmission.
1.6 Cable and Connection Considerations
• The cables may have been packaged without the locking rings installed. If so, you
should route the cables before you install the locking rings.
• After connecting a locking ring to a cable, make sure the ring is securely connected
and the O-ring is in place so the connection remains secure.
1.6.1 Power/NMEA 0183 Cable
• The wiring harness connects the device to power, NMEA 0183 devices, and a lamp or
a horn for visible or audible alerts.
• If it is necessary to extend the NMEA 0183 or alarm wires, you must use 22 AWG (.33
mm²) wire.
