Installation Instructions Part 1

G-Series Installation & Commissioning 58
5.1 General instructions
Equipment location
When deciding on the location of system components, consider the
following:
• Ignition hazards
• Ventilation
• Mounting surface
• Cable entry
• EMC installation guidelines
Ignition hazards
Ventilation
To ensure adequate airflow:
• Ensure that equipment is mounted in a compartment of suitable
size.
• Ensure that ventilation holes are not obstructed.
• Allow adequate separation of equipment.
Any specific requirements for each system component are provided
later in this chapter.
Mounting surface
Ensure equipment is adequately supported on a secure surface.
Do not mount units or cut holes in places which may damage the
structure of the vessel.
Any specific requirements for each system component are provided
later in this chapter.
Cable entry
Ensure the unit is mounted in a location which allows proper routing
and connection of cables:
• Minimum bend radius of 100 mm (3.94 in).
• Use cable supports to prevent stress on connectors.
EMC installation guidelines
Raymarine equipment and accessories conform to the appropriate
Electromagnetic Compatibility (EMC) regulations. This minimizes
electromagnetic interference between equipment, which could oth-
erwise affect the performance of your system.
Correct installation is required to ensure that EMC performance is
not compromised.
For optimum EMC performance, we recommend that:
• Raymarine equipment and the cables connected to it are:
i. At least 3 ft. (1 m) 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 7 ft. (2 m).
ii. More than 7 ft. (2 m) 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.
Potential ignition sources
The equipment in these instructions is NOT
approved for use in hazardous/flammable atmo-
spheres such as an engine room.
