Garmin International Inc A2552 Manuel D’Utilisation

Torque the hex bolts to 0.81 kgf-m (70 lfb-in. [6 lbf-ft.]) to fasten the

antenna to the pedestal without damaging the antenna or the mounting

hardware.

It may be necessary to drill 31.7 mm (1 ¼ in.) holes for routing the power or

network cable. The provided rubber cable grommet can be used to cover a

cable installation hole.
• The grommet does NOT provide a waterproof seal. To make the grommet

waterproof, marine sealant must be applied.

• If needed, the grommet can be trimmed to route both the power and the

network cable through the same hole.

• Additional cable grommets can be purchased from Garmin or a Garmin

dealer.

When installing the power and network 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, power and network 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 4).

◦ Incorrectly extended runs of cable may cause the radar to malfunction

due to insufficient power transmission.

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 will void the product warranty.

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 4).

Route the power cable to the radar and the voltage converter.

Use crimp connectors and heat-shrink tubing to connect the power cable to

the voltage converter.
The radar power cable contains a 7.5 A fuse which should not be removed

when connecting to the voltage converter.

Connect the voltage converter to the boat battery through a 15 A, slow-

blow fuse (not included).
The 15 A fuse (not included) between the voltage converter and battery is

in addition to the 7.5 A fuse included in the radar power cable. Both fuses

must be in place for the radar to function properly.

Connect the power cable to the POWER port on the radar.

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 will void 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.
