• 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 you must cut
the network cable.
• The ground cable is not included, and must connect to a water ground
location, not the negative terminal of the battery (Grounding the Radar,
page 4).
• 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 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 power cable, you must use the
appropriate wire gauge (Power Cable Extensions, page 3).
◦ 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 (Connecting
Directly to Power, page 3).
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 (Power Cable
Extensions, page 3).

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.
