Emc Installation Guidelines - Raymarine REALVISION 3D RV-3 Series Installation Instructions Manual

Item Description
1 Direction to vessel bow
2 Element angle and vessel side:
– ("12°"; "20°")
– (port, "P"; starboard, "S")
Single (all-in-one) transducers are marked "0°".
3 Vessel side and direction to vessel keel
Single (all-in-one) transducers omit this label.
– choose mounting positions that are symmetric about the center line of the vessel.
– choose mounting positions that are at least 300 mm (12 inches) below the water line.
• Transducers should be installed in a location where there is sufficient clearance inside the hull to
fit the nut and have at least 100 mm (4 in) of headroom to allow for withdrawal.
• To avoid interference with the internal magnetometer, mount transducers at least 1 m (39 inches)
from other electrical devices.
Cored fiberglass hull mounting
It is recommended that the transducer is mounted in a non-cored section, if installation in a cored
section is required then the area around the hole must be adequately strengthened to ensure it is
not damaged when tightening the hull and anti-rotation nuts.
Important: Installation in a cored fiberglass hull should only be carried out by a competent
marine installer.

EMC installation guidelines

Raymarine equipment and accessories conform to the appropriate Electromagnetic Compatibility
(EMC) regulations, to minimize electromagnetic interference between equipment and minimize the
effect such interference could have on the performance of your system
Correct installation is required to ensure that EMC performance is not compromised.
Note: In areas of extreme EMC interference, some slight interference may be noticed on the
product. Where this occurs the product and the source of the interference should be separated
by a greater distance.
For optimum EMC performance we recommend that wherever possible:
• Raymarine equipment and cables connected to it are:
– At least 1 m (3.3 ft) from any equipment transmitting or cables carrying radio signals e.g. VHF
radios, cables and antennas. In the case of SSB radios, the distance should be increased to 2
m (6.6 ft).
– More than 2 m (6.6 ft) from the path of a radar beam. A radar beam can normally be assumed to
spread 20 degrees above and below the radiating element.
