To avoid damaging the pedestal, you should stop tightening the threaded
rods when they no longer turn easily.
4
From under the mounting surface, place the included plastic shoulder
washers
Á
over the threaded rods and into the holes.
5
Place the flat washers
Â
, lock washers
Ã
, and hex nuts
Ä
on the
threaded rods.
6
Tighten the hex nuts to a torque of 14.7 N-m (11 lbf-ft.) to securely fasten
the radar to the surface without damaging the radar or the mounting
hardware.
Installing the Antenna
Before you can install the antenna on the radar, you must securely mount the
pedestal (Mounting the Radar, page 2).
1
Remove the protective cover
À
from the waveguide on the top of the
pedestal.
2
Align the waveguide on the pedestal
Á
with the socket on the bottom of
the antenna
Â
, and slide the antenna onto the pedestal.
3
Secure the antenna to the pedestal by tightening the captive hex bolts
under the antenna arm.
4
Tighten the hex bolts to a torque of 7.9 N-m (6 lbf-ft.) to fasten the antenna
to the pedestal without damaging the antenna or the mounting hardware.
Wiring and Connection Considerations
It may be necessary to drill 32 mm (1
1
/
4
) in. holes for routing the power,
network, or grounding 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 you must make the routing hole 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 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 4).
◦ 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 to
Power, page 4).
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 4).
