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

Suppression Ferrites
The following illustration shows typicalcable suppressionferrites used
with Raymarine equipment. Always usethe ferrites supplied by
Raymarine.

Power supply
The power supplyinstallation informationin thishandbook is valid for a
typical ST290 system witha total LEN ofup to 100 (seeSeaTalk
requirementson page 6-1-14).Larger systemsneed additional power
supplies.If the system you areintending toinstall willhave atotal LEN of
more than 100, please contact the Raymarine Technical Support
Department,or yourlocal Raymarine Dealer,for adviceon power supply
connection.
An ST290 system requires a 12 V dcsupply,connected in one of the
following ways:
• With the supply (normally a battery) connected to theDPU.
• From a RaymarineCourse Computer, via SeaTalk.
Note: If a battery is used as a power source, it is recommended that in order to avoid sudden voltage d rops, the battery used for engine starting is
NOT used to power ST290.
Refer to Section 6, Chapter 2 for power connection details.

Cable routing practices
When running cable,always observe the followingguidelines:
• If acable has to befed through the deck,always use a goodquality
deck gland.
• Where cables arefed through holes, alwaysuse grommets to prevent
chafing.

Securing cables and replacing cover
When theDPU cables have all been connected, secureeach cable tothe
loops onthe DPU, using the cable ties provided.
When all cables aresecure, replace theDPU cover.
Donotuse theDPUwiththe coverremoved,as this could degrade the
EMC performance.
2.5 Fitting Speed, Depth & Wind transducers
Each transducerconnects to SeaTALK2via a dedicatedPod, supplied
with thetransducer.These instructionsdescribehow tofit thetransducers
and runthe transducercables to the intendedlocations forthe Pods. At
each Podlocation, leave atleast 2 ft (600 mm) of transducer cable, to
facilitate future connection.
Speed & Depth
Instructions for installing and maintaining the Speed and Depth
transducers arepacked with the transducers. Install these transducer
types in accordance with theseenclosed instructions.
Running transducer cable
Speed andDepth transducers eachhave a 45 ft(13.7 m) cable, which
connects to therelevant Pod. Observingtheguidelines givenunder Cabl e
routing guidelinesnear the startof this chapter,run the cable to the
intended location forthe Pod.
ST290 Instrument System Owner’s Handbook
6-2-12 Section 6: Installation
Important point: DoNOT shorten the cablefrom the Depth transducer
as thiswill seriously degradetransducer performance. If theDepth
transducer cableis too long, coil the spare cablein an appropriate, safe
position.
Wind transducer
The Wind transducer is fitted with a 164 ft(50 m) cable, terminated with
spadeconnectors for connection tothe Windtransducer Pod.The manner
in which the cableis fitted will dependon the locations ofthe transducer
and Pod. The following guidelines areprovided:
• If the transducer is mounted ona masthead or otherstructure likelyto
be removed for maintenance or storage purposes, always incorporate
a disconnectionpoint as nearas possible tothe cable entry point into
the vessel. Thiscan beachieved eitherby positioning the Wind Pod at
an appropriate point, orif this is notpossible, by connecting thejunction boxsupplied, between the Wind transducer and Pod, nearthe
cable entry point.
• It maybe necessary to remove the spadeconnectors to facilitate
installation, e.g. ifyou want incorporate the junctionbox in the cable
run or if the cablehas to be routedthrough narrow apertures.
Assembling Wind Vane
Referring to Figure 2-1 1 ,assemble the wind vane, transducer body and
anemometer asfollows:
1. Insert the upperspindle of the transducer body intothe vane and
secure withthe grub screw.
2. Insert the lowerspindle of the transducer body into theanemometer
and securewith the grubscrew.

Running transducer cable
If theWind transducer isfitted ona masthead, remove the spade
connectors from thefree end ofthe cable, then feedthe free end ofthe
cable down insidethe mast.
• If the mastis a through-deck mast, feed the cable out through a suitable below-decks aperture.
• If themast is deck stepped,feed the cable throughthe deck, using a
proprietary deckgland.
If the Wind Pod issituated near to thecable entrypoint, crimp new spade
connectors onto the wires, as described under Cable preparationon page
6-2-5, then connect the cableto theWind Pod, asdescribed underFitting
transducer Pods. If theWind Podis not situatednear to the cable entry
point, fit thejunction box (see Figure 2-13 )inside the vessel, close to the
cable entrypoint, then:
1. Run the cableto the junction box, thenallowing sufficientcable to
connectinside thejunctionbox, cutthecable andconnecteachwire at
the free end of thecable from the transducer, to aseparate connector
inside the junction box.
2. Connect eachwire at one end of the remainingcable to thesame-colored wire insidethe junction box.
3. Run the cablefrom the junction box tothe intended location for the
Wind Pod.
4. Crimp new spadeconnectors onto the wires atthe Wind Pod endof
the cable, asdescribed above,and connect the cable tothe Wind Pod,

Requirements
CAUTION:
Incorrectly connected power supplies could cause damage to the
system. Ensure youdo NOT deviate from the procedures in this
handbook, when connectingpower.
The ST290system requires a 12 V dcsupply. Power canbe supplied
either from a separate 12 V dc source (preferably from a 12 V battery) or,
from SeaTalk.In either case,thepower sourcefor the ST290 system must
be protected bya 5 A fuse orcircuit breaker.
If your vessel onlyhas a 24 V supply, asuitable down-convertermust be
used toprovide 12 V.
Power for the system is connected to the DPU then distributed from there
to therest of thesystem via the SeaTalk and SeaTALK
Power supply capacity
The power supply information given here is valid for a typical ST290
system wherethe total of theLENs for all productson SeaTALK
or less(see Section 6, Chapter 1). If you are installing a large system
where thetotal of theLENs is in excessof 100, pleasecontact the
Raymarine Technical Support Department, or yourlocal Raymarine
Dealer foradvice on power supply connection.
Grounding the system
In orderto meet the systemEMC specification:
