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 sig-
• More than 7 ft. (2 m) from the path of a radar beam. A radar beam can normally
• 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 infor-
mation and may change the operating mode.
• Raymarine specified cables are used. Cutting and rejoining these cables can com-
promise 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.
nals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance
should be increased to 7 ft. (2 m).
be assumed to spread 20 degrees above and below the radiating element.
