Chapter 1: Preparation for installation 7Suppression FerritesThe illustration shows typical cable suppressionferrites used with Raymarine equipment. Alwaysuse the ferrites supplied by Raymarine.Connections to other equipmentIf your Raymarine equipment is to be connected to other equipment using a cable notsupplied by Raymarine, a suppression ferrite MUST always be attached to the cablenear to the Raymarine unit.Locating the displayYour E-Series display can either be flush-mounted or mounted using the trunnionbracket supplied.Before you install the display, plan its installation, considering:• Convenience: The contrast and colors seen on all Liquid Crystal Displays (LCD)vary slightly with viewing angle and are best viewed perpendicular to the display.The mounting location should be easily accessible to allow operation of the frontpanel controls. Avoid installing where excessive reflection will occur in normal use.• Access: There must be sufficient space behind the display to allow cable connec-tions to the rear panel connectors, avoiding tight bends in the cables.• Interference: The selected location should be far enough away from devices thatmay cause interference, such as motors, generators and radio transmitters/receiv-ers (see EMC Guidelines).• Magnetic compass: Mount the display at least 3ft (1m) away from a magneticcompass.• Cable runs: The display should be mounted as near as possible to a Direct Current(DC) power source. All cables should be adequately secured, protected from physi-cal damage and excessive vibration. Avoid running cables through bilges or door-ways, or close to moving or hot objects.• Environmental: The display should be protected from physical damage andexcessive vibration. Although the display unit is waterproof, it is good practice tomount it in a protected area away from prolonged and direct exposure to rain andsalt spray. The rear of the display should be in a well ventilated space to ensure aircirculation to the rear of the unit.EMC ConformanceAlways check the installation before going to sea to make sure that it is not affected byradio transmissions, engine starting etc.D6626-1
