5.1 Selecting a locationWarning: Potential ignition sourceThis product is NOT approved for use inhazardous/flammable atmospheres. Do NOT installin a hazardous/flammable atmosphere (such as inan engine room or near fuel tanks).General location requirementsWhen selecting a location for your display it is important toconsider a number of factors.Key factors which can affect product performance are:• VentilationTo ensure adequate airflow:– Ensure that equipment is mounted in a compartment ofsuitable size.– Ensure that ventilation holes are not obstructed. Allowadequate separation of equipment.Any specific requirements for each system component areprovided later in this chapter.• Mounting surfaceEnsure equipment is adequately supported on a securesurface. Do not mount units or cut holes in places which maydamage the structure 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 belowdecks. It is waterproof to IPX6 standard. Although the unit iswaterproof, it is good practice to locate it in a protected areaaway from prolonged and direct exposure to rain and saltspray.• Electrical interferenceSelect a location that is far enough away from devices thatmay cause interference, such as motors, generators and radiotransmitters / receivers.• Power supplySelect a location that is as close as possible to the vessel’s DCpower source. This will help to keep cable runs to a minimum.Compass safe distanceTo prevent potential interference with the vessel's magneticcompasses, ensure an adequate distance is maintained fromthe display.When choosing a suitable location for the multifunction displayyou should aim to maintain the maximum possible distancebetween the display and any compasses. Typically this distanceshould be at least 1 m (3 ft) in all directions. However for somesmaller vessels it may not be possible to locate the display thisfar away from a compass. In this situation, the following figuresprovide the minimum safe distance that should be maintainedbetween the display and any compasses.D12203-1200 mm(7.87 in)350 mm(13.8 in)300 mm(11.8 in)700 mm(27.5 in)500 mm(19.7 in)250 mm(9.84 in)1 23456ItemCompass position inrelation to displayMinimum safedistancefromdisplay1 Top 200 mm (7.87 in.)2 Rear 500 mm (19.7 in.)3 Right-hand side 350 mm (13.8 in.)4 Underside 300 mm (11.8 in.)5 Front 700 mm (27.5 in.)6 Left-hand side 250 mm (9.84 in.)GPS location requirementsIn addition to general guidelines concerning the location ofmarine electronics, there are a number of environmental factorsto consider when installing equipment with an internal GPSantenna.Mounting location• Above Decks mounting:Provides optimal GPS performance. (For equipment withappropriate waterproof rating.)• Below Decks mounting:GPS performance may be less effective and may require anexternal GPS antenna mounted above decks.D11537-21231231. This location provides optimal GPS performance (abovedecks).2. In this location, GPS performance may be less effective.3. This location is NOT recommended for GPS antenna.64 New a Series / New c Series / New e Series
