Cable Considerations

Page 2 highlights

• The device should be mounted at least 1 m (40 in.) away from cables carrying radio signals such as VHF radios, cables, and antennas. For Single Side Band (SSB) radios, increase the distance to 2 m (6 ½ ft.). Mounting the Radar Before you mount the radar, you must review the mounting location considerations and select a mounting location. NOTE: The supplied M8 x 1.25 x 60 threaded rods can be used on mounting thicknesses of 5 to 30 (recommended). For surfaces over 3m0mm(m3/1(61to3/116 3/16 in.) in.), use longer threaded rods. 1 If you are not installing the device on a pre-drilled Garmin compatible radar mount, use the included mounting template to drill four 9.5 mm (3/8 in.) mounting holes. 2 Connect the power cable to the power port and the network cable to the network port . 3 Press the cables into any of the guide grooves on the bottom of the case, and secure them using a cable holddown plate . The cables should be bent or twisted as little as possible. 4 Using the arrow on the bottom as a reference, position the radome on the mounting surface aligned to the front of the vessel. NOTE: If you choose not to align the dome with the front of the vessel, you can adjust the front-of-boat offset after the dome is installed (Setting the Front-of-Boat Offset, page 3). 5 Apply the included anti-seize compound to the threads of the four M8 x 1.25 x 60 threaded rods. 6 Insert the four threaded rods into the mounting holes on the bottom of the radome. Up to 50 mm (2 in.) of the threaded rods may extend below the radome. 7 Apply a bead of marine sealant on the mounting surface around each mounting hole. 8 Fasten the radome to the mounting surface using the threaded rods , flat washers , spring washers , and hex nuts . 9 Using a torque wrench, tighten the nuts to 13.7 to 18.6 N-m (10 to 14 lbf-ft.). Cable Considerations It may be necessary to drill 32 mm (11/4) in. holes for routing the power or network cables. • When routing both the power and network cables through the same hole, you must route the network cable before the power cable. • 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, 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 (Power Cable Extensions, page 3). ◦ Incorrectly extended runs of cable may cause the radar to malfunction due to insufficient power transmission. Connecting the Power Cable 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. 1 Route the power cable from the device to the power source. 2

The device should be mounted at least 1 m (40 in.) away
from cables carrying radio signals such as VHF radios,
cables, and antennas.
For Single Side Band (SSB) radios, increase the distance to
2 m (6 ½ ft.).
Mounting the Radar
Before you mount the radar, you must review the mounting
location considerations and select a mounting location.
NOTE:
The supplied M8 x 1.25 x 60 threaded rods can be used
on mounting thicknesses of 5 to 30 mm (
3
/
16
to 1
3
/
16
in.)
(recommended). For surfaces over 30 mm (1
3
/
16
in.), use longer
threaded rods.
1
If you are not installing the device on a pre-drilled Garmin
compatible radar mount, use the included mounting template
to drill four 9.5 mm (
3
/
8
in.) mounting holes.
2
Connect the power cable to the power port
and the
network cable to the network port
.
3
Press the cables into any of the guide grooves
on the
bottom of the case, and secure them using a cable hold-
down plate
.
The cables should be bent or twisted as little as possible.
4
Using the arrow on the bottom as a reference, position the
radome on the mounting surface aligned to the front of the
vessel.
NOTE:
If you choose not to align the dome with the front of
the vessel, you can adjust the front-of-boat offset after the
dome is installed (
Setting the Front-of-Boat Offset
,
page 3
).
5
Apply the included anti-seize compound to the threads of the
four M8 x 1.25 x 60 threaded rods.
6
Insert the four threaded rods into the mounting holes on the
bottom of the radome.
Up to 50 mm (2 in.) of the threaded rods may extend below
the radome.
7
Apply a bead of marine sealant on the mounting surface
around each mounting hole.
8
Fasten the radome
to the mounting surface
using the
threaded rods
, flat washers
, spring washers
, and
hex nuts
.
9
Using a torque wrench, tighten the nuts to 13.7 to 18.6 N-m
(10 to 14 lbf-ft.).
Cable Considerations
It may be necessary to drill 32 mm (1
1
/
4
) in. holes for routing the
power or network cables.
When routing both the power and network cables through the
same hole, you must route the network cable before the
power cable.
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, 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 (
Power Cable
Extensions
, page 3
).
Incorrectly extended runs of cable may cause the radar to
malfunction due to insufficient power transmission.
Connecting the Power Cable
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.
