Cabling guidelines
• consider how you will run cables to and from each component
• avoid running cables through bilges where possible
• avoid running cables close to fluorescent lights, engines, radio transmitting
equipment etc.
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, we recommend that:
• 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, increase the distance to 7 ft (2 m).
• More than 7 ft (2 m) from the path of a radar beam. A radar beam can nor-
mally 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.
