7.1 Warnings and cautions
Important:
Before proceeding, ensure that you have read and understood the
warnings and cautions provided in the following section of this document:
p.10 — Important information
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).
7.2 General location requirements
When selecting a location for your product it is important to consider a
number of factors.
Key factors which can affect product performance are:
• Ventilation — To ensure adequate airflow:
– Ensure that product is mounted in a compartment of suitable size.
– Ensure that ventilation holes are not obstructed. Allow adequate
separation of all equipment.
Any specific requirements for each system component are provided later
in this chapter.
• Mounting surface — Ensure product is adequately supported on a secure
surface. Do not mount units or cut holes in places which may damage
the structure of the vessel.
• Cabling — Ensure the product is mounted in a location which allows proper
routing, support and connection of cables:
– Minimum bend radius of 100 mm (3.94 in) unless otherwise stated.
– Use cable clips to prevent stress on connectors.
– If your installation requires multiple ferrites to be added to a cable then
additional cable clips should be used to ensure the extra weight of the
cable is supported.
• Water ingress — The product is suitable for mounting both above and
below decks. 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.
Caution: Product weight
• Refer to the technical specification for your product to
ensure the intended mounting surface is suitable to bear
its weight.
• 2 people may be required for installation of larger / heavier
products.
Rear access requirements
Access to the rear of the display and mounting surface is required to surface
and flush mount the display.
Ensure there is sufficient access and space behind the mounting surface to
attach and tighten the fixings and also to connect the cables.
7.3 GNSS (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 GNSS receiver.
Mounting location
• Above Decks (e.g. open air) mounting: Provides optimal performance. (For
equipment with appropriate waterproof rating.)
• Below Decks (e.g. enclosed space) mounting: Performance may be less
effective and may require an external antenna or receiver mounted above
decks.
