• 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.
Remember
Where constraints on the installation prevent any of the above
recommendations:
• Always allow the maximum separation possible between
different items of electrical equipment. This will provide the best
conditions for EMC performance for the installation.
Suppression ferrites
Raymarine cables may be fitted with suppression ferrites. These
are important for correct EMC performance. Any ferrite removed to
facilitate installation must be replaced in the original position
immediately when installation is complete.
Use only ferrites of the correct type, supplied by Raymarine
authorised dealers.
The following illustration shows a typical range of suppression
ferrites fitted to Raymarine equipment.
Connections to other equipment
If Raymarine equipment is to be connected to other equipment
using a cable not supplied by Raymarine, a suppression ferrite
MUST always be fitted to the cable close to the Raymarine unit.
