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.
• The product is supplied 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.
• Raymarine® specified cables are used.
• Cables are not cut or extended, unless doing so is detailed in the
installation manual.
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 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 the Raymarine® unit.
For more information, refer to your third-party cable manufacturer.
