EMC installation guidelinesRaymarine equipment and accessories conform to the appropriateElectromagnetic Compatibility (EMC) regulations, to minimizeelectromagnetic interference between equipment and minimize theeffect such interference could have on the performance of yoursystemCorrect installation is required to ensure that EMC performance isnot compromised.For optimum EMC performance we recommend that whereverpossible:• Raymarine equipment and cables connected to it are:– At least 1 m (3 ft) from any equipment transmitting or cablescarrying radio signals e.g. VHF radios, cables and antennas.In the case of SSB radios, the distance should be increasedto 7 ft (2 m).– More than 2 m (7 ft) from the path of a radar beam. A radarbeam can normally be assumed to spread 20 degrees aboveand below the radiating element.• The product is supplied from a separate battery from that usedfor engine start. This is important to prevent erratic behaviorand data loss which can occur if the engine start does not havea separate battery.• Raymarine specified cables are used.• Cables are not cut or extended, unless doing so is detailed inthe installation manual.Note: Where constraints on the installation prevent any ofthe above recommendations, always ensure the maximumpossible separation between different items of electricalequipment, to provide the best conditions for EMC performancethroughout the installationSuppression ferritesRaymarine cables may be fitted with suppression ferrites. Theseare important for correct EMC performance. If a ferrite has to beremoved for any purpose (e.g. installation or maintenance), it mustbe replaced in the original position before the product is used.Use only ferrites of the correct type, supplied by Raymarineauthorized dealers.Connections to other equipmentRequirement for ferrites on non-Raymarine cablesIf your Raymarine equipment is to be connected to other equipmentusing a cable not supplied by Raymarine, a suppression ferriteMUST always be attached to the cable near the Raymarine unit.Declaration of conformityRaymarine Ltd. declares that this product is compliant with theessential requirements of EMC directive 2004/108/EC.The original Declaration of Conformity certificate may be viewed onthe relevant product page at www.raymarine.com.Important information 9
