Chapter 4: Installing the Wheel Pilot
4.1 Planning the installation
Before you start installing your wheel pilot system, read through the
following information and the relevant installation sections in this
chapter.
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 normally be assumed to spread 20 degrees above
and below the radiating element.
