iiEMC installation guidelinesRaymarine equipment and accessories conform to the appropriate ElectromagneticCompatibility (EMC) regulations. This minimizes electromagnetic interferencebetween equipment, which could otherwise affect the performance of your system.Correct installation is required to ensure that EMC performance is not compromised.For optimum EMC performance, we make the following recommendations:• Place Raymarine equipment and cables at least 3 ft (1 m) from any equipment thattransmits, or cables that carry, radio signals from VHF radios, cables and anten-nas. In the case of SSB radios, the distance should be increased to 7 ft. (2 m).• Place Raymarine equipment and cables more than 7 ft (2 m) from the path of aradar beam. A radar beam can normally be assumed to spread 20 degrees aboveand below the radiating element.• Use a power source separate from that used for engine-start. This is important toprevent erratic behavior and data loss which can occur if the engine-start does nothave a separate battery.• Use Raymarine-specified cables.• Do not cut or extend cables unless doing so is detailed in the installation manual.RememberWhere constraints on the installation prevent any of the above recommendations:• Always allow the maximum separation possible between different items of electri-cal equipment.This will provide the best conditions for good EMC performance of the installation.Suppression ferritesRaymarine cables may be fitted with suppression ferrites. These are necessary forcorrect EMC performance. Any ferrite removed during installation must be replacedas soon as installation is complete.Use only ferrites of the correct type, supplied by Raymarine authorized dealers.Connections to other equipmentIf Raymarine equipment is to be connected to other equipment using a cable notsupplied by Raymarine, a Raymarine suppression ferrite MUST always be attachedto the cable near the Raymarine unit.General cabling guidelines• Do not mix AC and DC cables.• Adhere to EMC guidelines (above).• Use Copex conduit where appropriate to protect cables.• Label all cables for easy identification.• Keep fluxgate compass cable separate from other cables.
