3.2 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. 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 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 (7 ft).
– More than 2 m (7 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.
• The product is supplied power from a separate battery
from that used for engine start. This is important to
prevent erratic behavior and data loss which can occur
if the engine start does not have a separate battery.
• Only Raymarine® specified cables are used.
• Cables are not cut or extended, unless doing so is
detailed in the installation instructions.
Note:
Where constraints on the installation prevent any
of the above recommendations, always ensure the
maximum possible separation between different
items of electrical equipment, to provide the best
conditions for EMC performance throughout the
installation.

Suppression ferrites

• Raymarine cables may be pre-fitted or supplied with
suppression ferrites. These are important for correct
EMC performance. If ferrites are supplied separately
to the cables (i.e. not pre-fitted), you must fit the
supplied ferrites, using the supplied instructions.
• If a ferrite has to be removed for any purpose (e.g.
installation or maintenance), it must be replaced in the
original position before the product is used.
• Use only ferrites of the correct type, supplied by
Raymarine or its authorized dealers.
• Where an installation requires multiple ferrites to be
added to a cable, additional cable clips should be
used to prevent stress on the connectors due to the
extra weight of the cable.

Connections to other equipment

Requirement for ferrites on non-Raymarine cables.
If your product is to be connected to other equipment
using a cable not supplied by Raymarine, a suppression
ferrite MUST always be attached to the end of the cable
nearest to the Raymarine product.
