Failure to do so could result in personal injury, damage to your boat and/or poor product performance. WARNING: Electrical safety Make sure you have switched off the power supply before you start installing this product. WARNING: Navigational safety Although we have designed this product to be accurate and reliable, many factors can affect its performance. [. . . ] Fitting details and dimensions are given in the Fitting transducers section of this chapter. Instrument CAUTION: Keep the rear of the instrument dry Keep the rear of instrument dry. Failure to observe this caution could result in damage if water enters the instrument through the breathing hole or comes into contact with the electrical connectors. ST60+ instruments can be fitted either above or below deck, provided that the rear of the instrument is sited where it is protected from contact with water. Each instrument must also be positioned where it is: · Easily read by the helmsman. · Protected against physical damage. · At least 9 in (230 mm) from a compass. 10 ST60+ Rudder Angle Indicator Instrument Owner's Handbook · At least 20 in (500 mm) from radio receiving equipment. · Reasonably accessible from the rear for installation and servicing.

Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of 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 all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: · Raymarine equipment and cables connected to it are: 490 in (124 mm) 3. 54 in (90 mm) diameter 4. 53 in (115 mm) 3. 54 in (90 mm) diameter Chapter 3: Installation 11 · 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). · More than 7 ft (2 m) from the path of a radar beam. 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. · Raymarine specified cables are used. 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. [. . . ] Systems with a large number of instruments on the SeaTalk bus may require connections to the power supply from each end of the system (`ring-main' style), to maintain sufficient voltage throughout the system.

Power cables are available in 2 m and 9 m lengths. Ensure the intended power source is switched off. [. . . ]
