1.2 Planning the installation

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 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 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 operating mode.

•Raymarine specified cables are used. Cutting and rejoining these cables can compromise EMC performance and must 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 needs to be removed during installation it must be reassembled in the same position.

ST290 Instrument System Owner’s Handbook

Chapter 1: Preparing for Installation	6-1-7

Suppression Ferrites

The following illustration shows typical cable suppression ferrites used with Raymarine equipment. Always use the ferrites supplied by Raymarine.

D3548-2

Connections to Other Equipment

If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be attached to the cable near to the Raymarine unit.

Chapter 1: Preparing for Installation	6-1-9

Instruments & keypads

Templates to facilitate instrument and keypad installation are provided in Section 11 of this handbook.

The necessary mounting surface thickness for the different instrument and keypad types, are summarized in Table 1-1 .

Table 1-1: Mounting surface thickness

		Mounting surface
Product	Minimum thickness		Maximum thickness
Digital instruments	1/8	inch (3 mm)	1 inch (25 mm)
Analog instruments	1/8	inch (3 mm)	3/4	inch (20 mm)
Keypads	1/8	inch (3 mm)	3/4	inch (20 mm)

The maximum thicknesses given in Table 1-1 apply when using the standard fixing studs supplied with your ST290 product. If you want to install an ST290 product in a mounting surface thicker than the maximum quoted thickness, use an M4 stud x 0.7 mm pitch, of the appropriate length.

•Wind: 164 ft (50 m)

•Depth/Speed: 45 ft (13.7 m)

Wind

The Wind transducer is supplied with a junction box and a set of spade terminals. The intended location for the wind transducer must:

•Be as high as possible and away from any equipment which may shield the transducer or otherwise disturb the air flow.

•Allow reasonable access for installation and servicing.

•Provide a horizontal mounting surface. If a surface (e.g. mast top) is otherwise suitable but not horizontal, make up a suitable wedged packing piece to provide the necessary horizontal surface.

Each transducer should also:

•Be ahead of the propellers by at least 10% of the water line length.

•Be at least 6 in (150 mm) away from the keel (ideally ahead of the keel if a sailing yacht).

•Be as near as possible to the centre line of the vessel.

•Be clear of other through-hull fittings or projections.

•Have sufficient clearance inside the hull to enable the nut to be fitted.

•Have 4 in (100 mm) of space above it, to allow for withdrawal.

In addition to the above requirements, the depth transducer must be mounted within 10° of the vertical, forward, aft and athwart ships.

Further information

For advice or further information regarding the installation of any ST290 product, please contact the Raymarine Product Support Department or your local Raymarine dealer. Technical Support information in given in Section 5 of this handbook.

1.3 SeaTALK2 requirements

Each SeaTALK2 product is labelled with a Load Equivalency Number (LEN), to indicate how much power it consumes (see Table 1-3 ).

Table 1-3: Load Equivalence Numbers

Product	LEN
Digital instrument	6
DPU	5
Transducer Pods	1

In order to achieve optimum performance, always observe the following guidelines when installing SeaTALK2 cables:

•A terminator plug is required AT EACH END of the main SeaTALK2 cable run (see Figure 1-10 ).

Figure 1-10: SeaTALK2 dimensions

ST290 Instrument System Owner’s Handbook

Chapter 1: Preparing for Installation	6-1-15

•The total length of the SeaTALK2 main cable run must be no more than 655 ft (200 m). The main cable run is defined as the total length of cable between the two terminators. For example, in Figure 1-10 , the length of the main cable run is the sum of distances A+B+C+D+E.

•Where it is impractical to connect a product in a daisy-chained manner, a connector block and spur cable can be used. Where this method is used, the length of the spur cable must not exceed 3 ft (1 m).

•The sum of the LENs of all individual products in a SeaTALK2 system must not exceed 100. If this value exceeds 100 in the system you are planning, contact the Raymarine Technical Support Department or your local Raymarine Dealer for advice.

1.4System structures

Preliminary information

Before running cables, refer to Table 1-4 , to determine which bus type (SeaTalk or SeaTALK2) is required for each product you intend installing. A summary of the various ST290 components and their associated bus connections is shown in Table 1-4 .

Table 1-4: Bus allocations

Component	Bus connections
DPU	SeaTALK2 and SeaTalk. NMEA 2000, NMEA 0183
	and USB ports are also available.
Digital instruments (Graphic & Data)	SeaTALK2
Transducer Pods (all types)	SeaTALK2
Analog instruments (all types)	SeaTalk
Keypads (all types)	SeaTalk

Spend some time determining the best positions for the instruments and transducers, such that the conditions described under Planning the installation are satisfied. If you are planning to utilize the NMEA0183, NMEA2000 or USB interfaces, for other products (e.g. GPS), you must also take this into account when positioning your ST290 products.

In an ST290 system the Data Processing Unit (DPU) controls the operation of the system, and connects to the other system components via SeaTalk and SeaTALK2 buses. The Digital instruments and the
