Chapter 5: Installing the ST7001+ 475 Installing the ST7001+Any moisture or water vapor in this area could cause damage bycoming into contact with electrical connections, or condensationby entering the control unit through its breathing hole.Cabling guidelines• consider how you will run cables to and from the control unit• avoid running cables through bilges where possible• avoid running cables close to fluorescent lights, engines, radiotransmitting equipment etc.EMC installation guidelinesAll Raymarine equipment and accessories are designed to the bestindustry standards for use in the recreational marine environment.Their design and manufacture conforms to the appropriateElectromagnetic Compatibility (EMC) standards, but correctinstallation is required to ensure that performance is notcompromised.Although every effort has been taken to ensure that they will performunder all conditions, it is important to understand what factors couldaffect the operation of the product.The guidelines given here describe the conditions for optimum EMCperformance, but it is recognized that it may not be possible to meetall of these conditions in all situations. To ensure the best possibleconditions for EMC performance within the constraints imposed byany location, always ensure the maximum separation possiblebetween different items of electrical equipment.For optimum EMC performance, it is recommended 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, the distance should be increased to7 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 motor
