Chapter 5: Installation
5.1 Introduction
This chapter provides instructions to assist in planning the installation of
the Raynav 300 GPS Plotter aboard your vessel.
Note:
If you wish to practice using the
Raynav 300 GPS Plotter
before
installation, you can connect it, via a 1A quick blow fuse, to a 12VDC
power supply and operate it using the simulator mode, as described in
Chapter 2: Getting Started.
EMC Installation Guidelines
All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate
Electromagnetic Compatibility (EMC) standards, but correct installation
is required to ensure that performance is not compromised. Although
every effort has been taken to ensure that they will perform under all
conditions, it is important to understand what factors could affect the
operation of the product.
The guidelines given here describe the conditions for optimum EMC
performance, but it is recognized that it may not be possible to meet all of
these conditions in all situations. To ensure the best possible conditions
for EMC performance within the constraints imposed by any location,
always ensure the maximum separation possible between different items
of electrical equipment.
For
optimum
EMC performance, it is recommended that
wherever
possible
:
• Raymarine equipment and cables connected to it are:
• At least 3 ft (1 m) from any equipment transmitting or cables carry-
ing 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 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 radi-
ating element.
• The equipment is supplied from a separate battery from that used for
engine start. Voltage drops below 10 V, and starter motor transients,
can cause the equipment to reset. This will not damage the equipment,
but may cause the loss of some information and may change the oper-
ating mode.
