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.
• Viewing angle
The contrast and colors seen on all LCD units varies slightly with
viewing angle and are best viewed perpendicular to the display.
Avoid locations where excessive reflection will occur in normal use
• 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.
