[. . . ] For optimum EMC performance, it is recommended that wherever possible: · 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. In the case of SSB radios, the distance should be increased to 7 ft (2 m). A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. · The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manual. · If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position. Suppression Ferrites The following illustration shows typical cable suppression ferrites used with Raymarine equipment. Always use the ferrites supplied by Raymarine. 124_3c03. p65 6 09/05/01, 11:30 Chapter 3: Installation 7 D3548-2 Connections to Other Equipment If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be attached to the cable near the Raymarine unit. 3. 2 Siting the Heading Sensor The Heading Sensor must be fitted to a vertical or horizontal bulkhead (preferably forward facing), away from large ferrous objects such as the engine and other magnetic devices. If you have any doubts about the magnetic suitability of a chosen location, attach a hand bearing compass to the chosen site and then turn your vessel through 360°. Differences between the hand-bearing compass and the boat's compass should not exceed 10° on any heading. The Heading Sensor should be positioned as close as possible to the pitch and roll centre of the vessel, as shown in the following diagram. 124_3c03. p65 7 09/05/01, 11:30 8 Heading Sensor Owner's Handbook 0. 3L to 0. 5L L X 0. 3L to 0. 5L L D194-2 The compass is normally bulkhead mounted below decks. Although it is weatherproof, performance may be impaired due to the increased motion if it is mounted above deck. 3. 3 Installation Procedure To install the heading Sensor: 1. Hold the Heading Sensor mounting bracket (4) against the selected bulkhead. Outline the four fixing holes in the Heading Sensor mounting bracket (4). Secure the Heading Sensor mounting bracket (4) to the bulkhead using the four self-tapping screws (3) provided. The embossed arrow on the back of the bracket must be pointing skywards. Note: The Heading Sensor must be within 10° of the vertical and, ideally, positioned at the pitch and roll centre of the vessel. 124_3c03. p65 8 09/05/01, 11:30 Chapter 3: Installation 9 5. Assemble the Heading Sensor (1) to the Heading Sensor mounting bracket (4). The shaft protruding from the base of the unit must click positively into the slot in the base of the mounting bracket. Once such errors have been detected, the Heading Sensor corrects them automatically.
