Selecting A Location - Raymarine E90W Installation Instructions Manual

4.1 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.
46
– 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.
• Magnetic compass
Select a location that is at least 3 ft (1 m) away from a magnetic
compass.
• Power supply
Select a location that is as close as possible to the boat's DC
power source. This will help to keep cable runs to a minimum
Adequate space for cooling fins
Ensure adequate space around the cooling fins, in particular you
must avoid contact with any metal object or surface.
Both the cooling fins on the rear of the display and the screws
securing them MUST NOT be in contact with any metal objects
including any metallic part of the vessel structure. Failure to adhere
to this could result in unwanted current flow and in turn damage
to the vessel structure through the process of galvanic corrosion.
If this is a concern then the method of mounting must ensure
electrical isolation.
Viewing angle considerations
As display contrast, color and night mode performance are all
affected by the viewing angle, Raymarine recommends you
temporarily power up the display when planning the installation, to
enable you to best judge which location gives the optimum viewing
angle.
