General Location Requirements - Raymarine Ray260 User Manual

5.1 General location requirements

When selecting a location for the unit it is important to consider a
number of factors.
Antenna mounting and EME exposure
Ensure that the antenna is connected to the radio before
transmission.
Raymarine declares a Maximum Permissible Exposure (MPE)
radius of 1.5 metres (4.9 ft) (per OET Bulletin 65) for this system,
assuming 25 watts output to an omnidirectional antenna of 3dBi
gain or less.
For watercraft with suitable structures, the antenna base must
be at least 3.5 metres (11.5 ft) above the main deck to meet
the MPE for persons up to 2 metres (6.6 ft) tall. For watercraft
without such structures, the antenna must be mounted so that
its base is a minimum of 1.5 metres (4.9 ft) vertically from heads
of all persons.
The antenna must be isolated from the vessel's metalwork using
an insulated (e.g. plastic) mounting bracket.
Compass safe distance
To prevent potential interference with the vessel's magnetic
compasses, ensure an adequate distance is maintained from
the product.
When choosing a suitable location for the product you should
aim to maintain the maximum possible distance from any
compasses. Typically this distance should be at least 1 m (3 ft)
in all directions. However for some smaller vessels it may not
be possible to locate the product this far away from a compass.
In this situation, when choosing the installation location for your
product, ensure that the compass is not affected by the product
when it is in a powered state.
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.
Water ingress
Base station
Although the base station is waterproof to IPX6 standard, it is
recommended that the base station be mounted below decks,
in an area protected from prolonged and direct exposure to rain
and salt spray.
Handset and speakers
The handsets, passive speakers, and active speakers are
waterproof to IPX7 and can be mounted above or below decks.
Although the unit is waterproof, it is good practice to locate it in
an area protected 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 supply. This will help to keep cable runs to a minimum.
