30 ST1000 Plus & ST2000 Plus Tiller PilotsCabling 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 transmittingequipment etc.EMC installation guidelinesAll Raymarine equipment and accessories are designed to the best industrystandards for use in the recreational marine environment.Their design and manufacture conforms to the appropriate ElectromagneticCompatibility (EMC) standards, but correct installation is required to ensure thatperformance is not compromised.Although every effort has been taken to ensure that they will perform under allconditions, it is important to understand what factors could affect the operationof 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 allsituations.To ensure the best possible conditions for EMC performance within theconstraints imposed by any location, always ensure the maximum separationpossible 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 carryingradio signals e.g. VHF radios, cables and antennas. In the case of SSBradios, 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 radiatingelement.• The equipment is supplied from a separate battery from that used for enginestart. Voltage drops below 10 V, and starter motor transients, can cause theequipment to reset. This will not damage the equipment, but may cause theloss of some information and may change the operating mode.• Raymarine specified cables are used. Cutting and rejoining these cables cancompromise EMC performance and must be avoided unless doing so isdetailed in the installation manual.
