2.1 Planning

Warning: Product grounding
Before applying power to this product, ensure it has
been correctly grounded, in accordance with the
instructions in this guide.
Caution: Do NOT connect to positive
ground system
Do NOT connect this product to a
positively-grounded system.
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.
For optimum EMC performance we recommend that wherever
possible:
• Raymarine equipment and cables connected to it are:
– At least 1 m (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 7 ft (2 m).
– More than 2 m (7 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.
Note: Where constraints on the installation prevent any of
the above recommendations, always ensure the maximum
possible separation between different items of electrical
equipment, to provide the best conditions for EMC performance
throughout the installation
