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, the grommet can be trimmed to enable you to
route both the network and the power cable 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 network and power 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.
• Cables should not be run near moving objects and high-heat
sources or through doorways and bilges.
• To avoid interference with other equipment, network and
power cables should not be run 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.
• The power cable should be installed as close to the battery
source as possible.
◦ If it is necessary to extend the power cable, the
appropriate gauge of wire must be used (
).
◦ Incorrectly extended runs of cable may cause the radar to
malfunction due to insufficient power transmission.
Connecting to Power Through the Voltage Converter
WARNING
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.
NOTICE
Do not reuse any voltage converters from previous Garmin radar
models, or third party voltage converters. Using any converter
other than one included with the radar may damage the radar or
prevent it from turning on.
Some radar models require a voltage converter unit to properly
power the device. If your model is packaged with a voltage
converter, it must be installed in order for your radar to function.
If your model is not packaged with a voltage converter, connect
the power cable directly to the boat battery (
).
When installing the voltage converter for an applicable radar
model, observe these considerations.
• The voltage converter requires an input voltage of 10 to
32 Vdc.
• It is recommended to install the voltage converter as close as
possible to the power source.
• Connecting the power cable for the voltage converter directly
to the battery is recommended. If it is necessary to extend
the cable, the appropriate gauge of wire must be used for the
length of the extension (
).

Use crimp connectors and heat-shrink tubing to connect the
power cable to the voltage converter.
The radar power cable contains a 10 A fuse which should not
be removed when connecting to the voltage converter.
3
Connect the voltage converter to the boat battery through the
included 30 A fuse.
The 30 A fuse between the voltage converter and battery is in
addition to the 10 A fuse included in the radar power cable.
Both fuses must be in place for the radar to function properly.
4
Connect the power cable to the POWER port on the radar.
Connecting Directly to Power
WARNING
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.
Some radar models do not require a voltage converter unit. If
your model is packaged without a voltage converter, it should be
connected directly to power.
