INSTALLATION AND WIRING

NOTICE
Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage coating and plastic parts, especially plastic connectors.

Mounting Considerations

Select a mounting location, keeping in mind the following points:

• Install the antenna unit on the hardtop, radar arch or on a mast on an appropriate platform.
  

• Locate the antenna where there is a good all-round view. Where possible, there should be no obstructions to the scanning beam such as superstructure or rigging.
  Obstructions cause shadow sectors and decrease the overall performance of the radar. The loss of performance can cause false echoes and reduce the quality of the observed images. A mast for instance, with a diameter considerably less than the horizontal beam width of the radiator, will cause only a small shadow sector.
  However, a horizontal spreader, or cross trees in the same horizontal plane as the antenna unit, would be a much more serious obstruction. You would need to place the antenna unit well above or below it. Be sure there are no metallic objects near the antenna.
  

• It is rarely possible to place the antenna unit where a completely clear view in all directions is available. After fitting the antenna, determining any shadow sectors, their angle and bearing, and their influence on the radar is recommended.

• In order to reduce electrical interference, avoid routing the power cable near other electrical equipment on-board. Also, avoid running the cable in parallel with other power cables.

• It is not recommended to install the antenna unit on the hardtop of a cabin. Vibrations from the antenna unit will pass through the hardtop and into the cabin.
  

• Setup the antenna unit position on the FURUNO Multi Function Display after installing the unit, referring to the chapter 2. If the antenna unit position is not setup correctly, the radar echoes on the display may not be aligned with the actual target’s bearing.

• Select a location that does not allow water to accumulate at the installation location.

• A magnetic compass will be affected if the antenna unit is too close to the compass.
  Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS to prevent interference to a magnetic compass.

• To ensure proper emission of radar waves, do not paint the radiator.

• Referring to the outline drawings at the back of this manual, allow space for maintenance and service.

• When this antenna unit is to be installed on a large vessel, consider the following points:

  • The supplied cable assembly runs between the antenna unit and display (or ethernet HUB) and comes in lengths of 10 m, 15 m, 20 m or 30 m. Select the appropriate length when purchasing.
  • Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial performance and hot gases may distort the antenna unit. The antenna unit must not be mounted where the temperature is more than 55°C(131°F).
