EMC Installation Guidelines

The design and manufacture of Raymarine equipment and accessories
conforms to the appropriate Electromagnetic Compatibility (EMC)
standards, but good installation is required to ensure that
performance is not compromised.
To avoid the risk of operating problems, all Raymarine equipment and
cables connected to it should be;
• At least 1m (3 feet) 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 2m (7ft).
• More than 2m (6ft) 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 equipment should be supplied from a different battery than the
one used for engine start. Voltage drops below 10v in the power
supply to our products can cause the equipment to reset. This will
not damage the equipment, but will cause the loss of some
information and can change the operating mode.
• Genuine Raymarine cables should be used at all times. Cutting and
rejoining these cables can compromise EMC performance and so
should be avoided unless doing so is detailed in the installation
manual.
• If a suppression ferrite is attached to a cable, this ferrite should not
be removed. If the ferrite has to be removed during installation it
must be reassembled in the same position.
If your Raymarine equipment will 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.
The following illustration shows the range of suppression ferrites
fitted to Raymarine equipment.
