Location and mounting

Selecting a location
General location requirements
When selecting a location for the unit it is important to
consider a number of factors.
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.
Mounting surface requirements
Ensure units are adequately supported on a secure
surface. Do NOT mount units or cut holes in places
which may damage the structure of the vessel.
Cable routing requirements
Ensure the unit is mounted in a location which allows

proper routing and connection of cables:
• Minimum cable bend radius of 100 mm (3.94 in) is
required unless otherwise stated.
• Use cable supports to prevent stress on connectors.
Electrical interference
Select a location that is far enough away from
devices that may cause interference, such as motors,
generators and radio transmitters/receivers.
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:
D12823-1
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.

antenna.
Vessel construction
The construction of your vessel can have an impact
on GPS performance. For example, the proximity of
heavy structure such as a structural bulkhead, or the
interior of larger vessels may result in a reduced GPS
signal. Before locating equipment with an internal GPS
antenna below decks, seek professional assistance
and consider use of an external GPS antenna mounted
above decks.
Prevailing conditions
The weather and location of the vessel can affect the
GPS performance. Typically calm clear conditions
provide for a more accurate GPS fix. Vessels at
extreme northerly or southerly latitudes may also
receive a weaker GPS signal. GPS antenna mounted
below decks will be more susceptible to performance
issues related to the prevailing conditions.
