Chapter 2: Installing the system

Before proceeding with the installation, ensure you have the following to hand:

• All necessary equipment and tools to install your SPX-5 Sport system.

• The correct type and length of power cable.

• Schematic diagram detailing autopilot system location and connections.

You should also check that existing marine electronics, such as the GPS are installed

and working.

2.1 Installation requirements

EMC installation guidelines

Raymarine equipment and accessories conform to the appropriate Electromagnetic

Compatibility (EMC) regulations. This minimizes electromagnetic interference

between equipment, which could otherwise 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 sig-

nals e.g. VHF radios, cables and antennas. In the case of SSB radios, the dis-

tance 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 man-

ual.

Remember

Where constraints on the installation prevent any of the above recommendations:

• Always allow the maximum separation possible between different items of electri-

cal 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 after the installation is complete.

• Use only ferrites of the correct type, supplied by Raymarine authorized dealers.

WARNING: Install at dockside

For safety reasons your boat must be securely moored at dockside

with power switched off, before commencing installation.
