EMC conformance
All Raymarine equipment and accessories are designed to the best industry standards
for use in the recreational marine environment. The design and manufacture of
Raymarine equipment and accessories conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to ensure that
performance is not compromised.
EMC installation guidelines
All Raymarine equipment and accessories are designed to the best industry standards for use in the
recreational marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC)
standards, but correct installation is required to ensure that performance is not compromised. Although
every effort has been taken to ensure that they will perform under all conditions, it is important to
understand what factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that
it may not be possible to meet all of these conditions in all situations. To ensure the best possible
conditions for EMC performance within the constraints imposed by any location, always ensure the
maximum separation possible between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever possible:
•
Raymarine equipment and cables connected to it are:
•
At least 3 ft. (1 m) 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 7 ft.
(2 m).
•
More than 7 ft. (2 m) from the path of a radar beam. A radar beam can normally be assumed to
spread 20 degrees above and below the radiating element.
•
The equipment is supplied from a separate battery from that used for engine start. Voltage drops
below 10 V, and starter motor transients, can cause the equipment to reset. This will not damage the
equipment, but may cause the loss of some information and may change the operating mode.
•
Raymarine specified cables are used. Cutting and rejoining these cables can compromise EMC
performance and must be avoided unless doing so is detailed in the installation manual.
•
If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to
be removed during installation it must be reassembled in the same position.
Suppression Ferrites
The illustration shows typical cable suppression ferrites used with Raymarine
equipment. Always use the ferrites supplied by Raymarine.
Connections to Other Equipment
If your Raymarine equipment is to be connected to other equipment using a cable
not supplied by Raymarine, a suppression ferrite MUST always be attached to the
cable near to the Raymarine unit.
