4.1 Selecting a locationGeneral location requirementsWhen selecting a location for your display it is important to considera number of factors.Key factors which can affect product performance are:• VentilationTo ensure adequate airflow:– Ensure that equipment is mounted in a compartment of suitablesize.– Ensure that ventilation holes are not obstructed. Allowadequate separation of equipment.Any specific requirements for each system component areprovided later in this chapter.• Mounting surface.Ensure equipment is adequately supported on a secure surface.Do not mount units or cut holes in places which may damage thestructure of the vessel.• Cable entryEnsure the unit is mounted in a location which allows properrouting and connection of cables:– Minimum bend radius of 100 mm (3.94 in) unless otherwisestated.– Use cable supports to prevent stress on connectors.• Water ingressThe display is suitable for mounting both above and below decks.It is waterproof to IPX6 standard. Although the unit is waterproof,it is good practice to locate it in a protected area away fromprolonged and direct exposure to rain and salt spray.• Electrical interferenceSelect a location that is far enough away from devices thatmay cause interference, such as motors, generators and radiotransmitters/receivers.• Magnetic compassSelect a location that is at least 3 ft (1 m) away from a magneticcompass.• Power supplySelect a location that is as close as possible to the boat’s DCpower source. This will help to keep cable runs to a minimumViewing angle considerationsAs display contrast, color and night mode performance are allaffected by the viewing angle, Raymarine recommends youtemporarily power up the display when planning the installation, toenable you to best judge which location gives the optimum viewingangle.Viewing angle80° 80° 80°80°D12062-1Note: The angles are provided for a contrast ratio of equal toor greater than 10.30 i70 Instrument display Installation instructions
