6.1 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:
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).
6.2 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.
6.3 EMC installation guidelines
Raymarine® equipment and accessories conform to the appropriate
Electromagnetic Compatibility (EMC) regulations, to minimize electromagnetic
interference between equipment and minimize the effect such interference
could have on the performance of your system.
Correct installation is required to ensure that EMC performance is not
compromised.
Note:
In areas of extreme EMC interference, some slight interference may be
noticed on the product. Where this occurs the product and the source of
the interference should be separated by a greater distance.
For
optimum
EMC performance we recommend that wherever possible:
• Raymarine® equipment and cables connected to it are:
– At least 1 m (3.3 ft) from any equipment transmitting or cables carrying
radio signals e.g. VHF radios, cables and antennas. In the case of SSB
radios, the distance should be increased to 2 m (6.6 ft).
– More than 2 m (6.6 ft) from the path of a radar beam. A radar beam
can normally be assumed to spread 20 degrees above and below the
radiating element.
• The product is supplied from a separate battery from that used for engine
start. This is important to prevent erratic behavior and data loss which can
occur if the engine start does not have a separate battery.
• Raymarine® specified cables are used.
• Cables are not cut or extended, unless doing so is detailed in the
installation manual.
