1.2 Planning the installation
EMC Installation Guidelines
All Raymarineequipment and accessories are designed to the best
industry standards foruse in the recreational marineenvironment.
Their design and manufacture conforms to the appropriate
Electromagnetic Compatibility (EMC) standards,but correctinstallation
is required to ensure that performance is not compromised. Although
every effort has beentaken to ensure that they will performunder all
conditions, it isimportant to understand what factors could affect the
operation of theproduct.
The guidelines given here describe the conditions foroptimum EMC
performance, but it isrecognized that itmay notbe possible to meet allof
these conditions in allsituations. To ensure the bestpossible conditions
for EMC performance within the constraints imposed by any location,
always ensure themaximum separationpossible betweendifferent items
of electricalequipment.
For optimumEMC performance, it isrecommended that wherever
possible:
• Raymarine equipment and cablesconnected 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 ofSSB radios, the distance should be increased to 7 ft (2 m).
• More than 7ft (2 m)from the path ofa radar beam.A radar beam
can normally beassumed to spread 20degrees above and below
the radiating element.
• The equipment is supplied from a separate battery from that used for
engine start. Voltage drops below10 V, and startermotor transients,
can causethe equipmentto reset. This willnot damage the equipment,but maycause theloss ofsomeinformationand may changethe
operating mode.
• Raymarine specified cables are used.Cutting and rejoining these
cables cancompromise EMC performance and must be avoided
unless doing sois detailed in the installation manual.
• If a suppression ferrite isattached to a cable, thisferrite shouldnot be
removed. Ifthe ferriteneeds tobe removed duringinstallation 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 typicalcable suppressionferrites used
with Raymarine equipment. Always usethe ferrites supplied by
Raymarine.
D3548-2
Connections to Other Equipment
Ifyour Raymarineequipmentis tobeconnected tootherequipment using
a cablenot suppliedby Raymarine, a suppressionferrite MUSTalways
be attachedto the cable near tothe Raymarine unit.

Each ST290instrument and keypad canbe fitted either above or below
deck, provided:
• The rearof each product isprotected from water.
• Instruments are easilyread by the helmsman.
• Keypads are easily operable.
• Each product isprotected against physical damage.
• Each product isat least 9 in (230 mm)from a compass.

• There isreasonable rear access for installation and servicing.
Wind, Speed & Depth transducers
Cable lengths
The Wind, Speed and Depth transducer types connect toSeaTALK2via
an associatedPod. The transducers are suppliedwith fittedcables, as
follows:
• Wind:164 ft (50 m)
• Depth/Speed: 45 ft (13.7 m)
Wind
The Wind transducer is suppliedwith a junction boxand a set ofspade
terminals. The intendedlocation for the windtransducer must:
• Be as high as possible and awayfrom any equipment whichmay
shield the transduceror otherwise disturb theair flow.
• Allow reasonableaccess for installationand servicing.
• Provide a horizontalmounting surface. If a surface (e.g. masttop) is
otherwise suitable butnot horizontal,make up a suitablewedged
packing pieceto provide the necessary horizontal surface.

Each transducershould also:
• Be ahead of the propellersby at least 10% of thewater line length.
• Be at least 6 in (150 mm)away from thekeel (ideally aheadof the
keel if asailing yacht).
• Be as near as possibleto the centreline of thevessel.
• Be clear of other through-hull fittings or projections.
• Have sufficient clearance inside the hull toenable the nut tobe fitted.
• Have 4 in (100 mm) of space aboveit, to allow forwithdrawal.
In additionto the above requirements, the depth transducer must be
mounted within 10° of the vertical, forward,aft and athwart ships.

• The total length of the SeaTALK2main cable run must be no more
than 655 ft(200 m). The main cable run isdefined as thetotal length
of cablebetween the twoterminators. For example,in Figure 1-10 ,
thelength ofthe main cable run isthe sum of distances A+B+C+D+E.
• Where itis impractical to connect a productin a daisy-chained manner,a connectorblock and spur cable can beused. Where thismethod
is used, thelength of the spurcable must not exceed 3 ft (1 m).
• The sum ofthe LENs of allindividual products in a SeaTALK
2
system must notexceed 100. If this value exceeds100 in the system you
are planning, contact the Raymarine Technical Support Department
or your local Raymarine Dealer foradvice.

transducers, such that theconditions describedunder Plannin g the
installation are satisfied. If youare planning toutilize the NMEA0183,
NMEA2000 or USBinterfaces, for other products (e.g. GPS), youmust
also take this into account whenpositioning your ST290 products.
