3.1 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 the unit it is important to
consider a number of factors.
To ensure optimum performance, it is recommended
that the display is temporarily powered up and tested, at
the chosen location, prior to installation.
Ventilation requirements
To provide adequate airflow:
• Ensure that equipment is mounted in a compartment
of suitable size.
• Ensure that ventilation holes are not obstructed.
• Ensure adequate separation of equipment.
Water ingress
Base station — Although the Base station is waterproof
to IPx6 and IPx7, it is recommended that the Base station
is mounted below decks, in an area protected from
prolonged and direct exposure to rain and salt spray.
Wired handset — The Handset has been designed to
be mounted above or below decks and is rated to IPx6
and IPx7.
Wired (Passive) speaker — The speakers has been
designed to be mounted above or below decks and are
rated to IPx6 and IPx7.
Mounting surface requirements
When selecting a mounting surface ensure:
• the product will be adequately supported on a secure,
flat surface. Do NOT mount units or cut holes in places
which may damage the structure of the vessel.
• sufficient space is available around the product.
• there is nothing behind the mounting surface that may
be damaged when drilling.
Cable routing requirements
Ensure you have identified the route that all required
cables will take and that sufficient space is available to
allow connection of cables:
• Unless otherwise stated, a minimum cable bend
radius of 100 mm (3.94 in) is required.
• Where necessary, cable supports should be used to
prevent stress on connectors.
Electrical interference
Select a location that is far enough away from equipment
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 supply. This will help to keep cable
runs to a minimum.
RF interference
Certain third-party external electrical equipment can
cause Radio Frequency (RF) interference with GNSS
(GPS), AIS or VHF devices, if the external equipment is
not adequately insulated and emits excessive levels of
electromagnetic interference (EMI).
Some common examples of such external equipment
include LED lighting (e.g.: navigation lights, searchlights
and floodlights, interior and exterior lights) and terrestrial
TV tuners.
To minimize interference from such equipment:
• Keep it as far away from GNSS (GPS), AIS or VHF
products and their antennas as possible.
• Ensure that any power cables for external equipment
are not entangled with the power or data cables for
these devices.
• Consider fitting one or more high frequency
suppression ferrites to the EMI-emitting device. The
ferrite(s) should be rated to be effective in the range
100 MHz to 2.5 GHz, and should be fitted to the power
cable and any other cables exiting the EMI-emitting
device, as close as possible to the position where the
cable exits the device.
Compass safe distance
When choosing a suitable location for your product you
should aim to maintain the maximum possible distance
between the product and any installed compass. This
distance should be at least 1 m (3 ft) in all directions. For
smaller vessels it may not be possible to achieve this
distance. In this situation ensure that the compass is not
affected by the product when it is powered on.
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.
