Chapter 2: Installation

2.1 Preparation for installation

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:

• At least 3 ft (1 m) 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 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 installation is complete.

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

Connections to non-Raymarine equipment

If Raymarine equipment is to be connected to other equipment using a cable not

supplied by Raymarine, a Raymarine suppression ferrite MUST always be attached

to the cable near the Raymarine unit.

Tools required

Before installing SeaTalk

, ensure you have the appropriate tools. In most cases, a

typical fitter’s toolkit should suffice, provided it has tools to enable you to:

• Drill holes for cable runs.

• Connect prepared bare wire ends to terminal blocks.
