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 facts could affect the operation of the
product.
The guidelines here describe the conditions for optimum EMC performance,
but it is recognized that it may not be possible to meet all of these condi-
tions 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 wherever possible:
• Raymarine equipment and cables connected to it are:
• At least 3 ft. (1m) from any other equipment transmitting or
carrying radio signals. In the case of Single Side Band (SSB) radio,
the distance should be increased to 7 ft. (2m).
• More than 7 ft. (2m) 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 to that used for
engine start. Voltage drops below 10.8 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 oper-
ating mode.
• Only Raymarine-specified cables must be used. Cutting and rejoining
these cables can compromise EMC performance.
