Selecting A Location - Raymarine a67 Wi-Fi Installation And Operation Instructions Manual

5.1 Selecting a location

Warning: Potential ignition source
This product is NOT approved for use in
hazardous/flammable atmospheres. Do NOT install
in a hazardous/flammable atmosphere (such as in
an engine room or near fuel tanks).
General location requirements
When selecting a location for your display it is important to
consider a number of factors.
Key factors which can affect product performance are:
• Ventilation
To ensure adequate airflow:
– Ensure that equipment is mounted in a compartment of
suitable size.
– Ensure that ventilation holes are not obstructed. Allow
adequate separation of equipment.
Any specific requirements for each system component are
provided 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 the structure of the vessel.
• Cable entry
Ensure the unit is mounted in a location which allows proper
routing and connection of cables:
– Minimum bend radius of 100 mm (3.94 in) unless otherwise
stated.
– Use cable supports to prevent stress on connectors.
• Water ingress
The 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 from prolonged and direct exposure to rain and salt
spray.
• Electrical interference
Select a location that is far enough away from devices that
may cause interference, such as motors, generators and radio
transmitters / receivers.
• Power supply
Select a location that is as close as possible to the vessel's DC
power source. This will help to keep cable runs to a minimum.
Compass safe distance
To prevent potential interference with the vessel's magnetic
compasses, ensure an adequate distance is maintained from
the display.
When choosing a suitable location for the multifunction display
you should aim to maintain the maximum possible distance
between the display and any compasses. Typically this distance
should be at least 1 m (3 ft) in all directions. However for some
smaller vessels it may not be possible to locate the display this
far away from a compass. In this situation, the following figures
provide the minimum safe distance that should be maintained
between the display and any compasses.

GPS location requirements
In addition to general guidelines concerning the location of
marine electronics, there are a number of environmental factors
to consider when installing equipment with an internal GPS
antenna.
Mounting location
• Above Decks mounting:
Provides optimal GPS performance. (For equipment with
appropriate waterproof rating.)
• Below Decks mounting:
GPS performance may be less effective and may require an
external GPS antenna mounted above decks.
1. This location provides optimal GPS performance (above
decks).
2. In this location, GPS performance may be less effective.
3. This location is NOT recommended for GPS antenna.
