8 Type 150/400 Autopilot System: Installation GuideStep 2For optimum EMC performance, we recommend that whereverpossible:• Raymarine equipment and cables connected to it are:• At least 3 ft (1 m) from any equipment transmitting or cablescarrying radio signals e.g. VHF radios, cables and antennas.In the case of SSB radios, increases the distance to 7 ft (2 m).• More than 7 ft (2 m) from the path of a radar beam. A radarbeam can normally be assumed to spread 20 degrees aboveand below the radiating element.• The equipment is supplied from a separate battery from that usedfor engine start. Voltage drops below 10 V, and starter motortransients, can cause the equipment to reset. This will not damagethe equipment, but may cause the loss of some information andmay change the operating mode.• Raymarine specified cables are used. Cutting and rejoining thesecables can compromise EMC performance and must be avoidedunless doing so is detailed in the installation manual.• If a suppression ferrite is attached to a cable, this ferrite should notbe removed. If the ferrite needs to be removed during installationit must be reassembled in the same position.Suppression ferritesThis following illustration shows typical cable suppression ferritesused on Raymarine equipment. Always use the ferrites supplied byRaymarine.Connections to other equipmentIf your Raymarine equipment is to be connected to other equipmentusing a cable not supplied by Raymarine, a suppression ferrite MUSTalways be attached to the cable near to the Raymarine unit.D3548-2
