Chapter 3: Installation

EMC guidelines

All Raymarine equipment and accessories are designed to the best

industry standards for use in the leisure marine environment.

Their design and manufacture conforms to the appropriate

Electromagnetic Compatibility (EMC) standards, but correct

installation is required to ensure that EMC 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 this product.

To minimise the risk of operating problems:

• All ST60 instruments, transducers and associated cabling should

be:

• At least 1 m (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 2 m (7

ft).

• More than 2 m (6 ft) from the path of a radar beam. A radar beam

can normally be assumed to spread 20

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 10 V 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.

Suppression ferrites

The following illustration shows the typical range of suppression

ferrites fitted to Raymarine equipment. Always use the ferrites

specified by Raymarine.
