Any moisture or water vapor in this area could cause damage by
coming into contact with electrical connections, or condensation
by entering the control unit through its breathing hole.
Cabling guidelines
• consider how you will run cables to and from the control unit
• 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, 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 signals e.g. VHF radios, cables and antennas.
In the case of SSB radios, the distance should be increased to
7ft (2m).
• More than 7 ft (2 m) 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 from that used
for engine start. Voltage drops below 10 V, and starter motor
