Table 1-1on page4 for alist ofthe differentsensor,material and

mountingtypes available.

General

Raymarinefishfindersrequire a transducer, eitherthru-hull, in-hull,

ortransom-mount.

Transducerscan measure water depth, temperature, distance

traveled,and/or speed.It is importantto position yourtransducer

correctly, as described inSection 1.4, SelectingtheEquipment

Location.

Note:Ifspeed andtemperatureare beinginput viaSeaTalk, these

valuesaredisplayed insteadof thespeedand temperature inputs

from the transducer.

EMC Installation Guidelines

All Raymarineequipmentand accessoriesare designed to thebest

industry standardsfor use inthe leisuremarineenvironment.

Theirdesign andmanufactureconformstothe appropriate

Electromagnetic Compatibility (EMC) standards, but correct

installation isrequired to ensure thatperformance isnot

compromised.Although every efforthas beentakento ensure that

theywillperform under allconditions,it is important tounderstand

whatfactorscould affectthe operationoftheproduct.

TheguidelinesgivenheredescribetheconditionsforoptimumEMC

performance,but itis recognized thatitmay not bepossibleto meet

allofthese conditionsin allsituations.To ensurethe bestpossible

conditionsforEMCperformance withinthe constraints imposedby

any location,always ensurethe maximum separationpossible

betweendifferent itemsof electrical equipment.

For optimumEMC performance, it isrecommended that wherever

possible:

• Raymarineequipment and cables connected toit are:

• At least 1m (3ft) fromany equipmenttransmitting or cables

carrying radio signals,e.g.,VHF radios,cablesandantennas.

In the caseof SSBradios, the distanceshould be increased to

2 m(7 ft).

• More than2 m(7 ft) from the path ofa radarbeam. Aradar

beamcan normallybe assumedtospread 20degrees above

andbelowtheradiating element.

• The equipmentis supplied from a separatebattery fromthat used

forenginestart.Voltagedrops below 10 V (20 Vfor 10 kW open

arrayscanners)in the power supplyto our products,and starter

motortransients,can cause the equipmentto reset. Thiswillnot

damagetheequipment,butmay causethe lossofsome informa-

tionand may changethe operating mode.

• Raymarinespecified cablesare usedat alltimes. Cuttingand

rejoiningthesecablescancompromiseEMCperformanceandso

mustbe avoidedunlessdoingsois detailedinthe documentation.

• Ifasuppressionferriteisattachedtoacable,thisferriteshouldnot

1.5 Cable Runs

Consider the following before installing the system cables:

• You needto attachthe power cable andthe transducer cable.

Additionalcables will be requiredifyou are installing aninte-

grated system.

• Allcablesshouldbe adequatelysecured,protected fromphysical

damageand protectedfrom exposure to heat.Avoidrunning

cablesthroughbilgesordoorways,or close to movingor hot

objects.

• Acute bendsmustbe avoided

• Where acablepassesthrough anexposedbulkheadordeckhead,

awatertightfeed-through should beused.

• Secure cablesin placeusing tie-wraps or lacingtwine. Coil any

extra cable and tie it out of the way.

thecable, ensurethat anyholes youdrillarelargeenough toaccept

theconnector, withthenut removed.

Afterthecablehas beenrunthroughthe holes, thisnut must be

attached beforethe cablecan beconnected, asdescribed in

TransducerCable Connections onpage 39.

CAUTION:

Donot cutthe transducer cableor removetheconnector.Donot

trytoshortenorsplice thecable. Ifthe cableis cut,it cannotbe

repaired.Cuttingthecablewillalso voidthewarranty.

• ForaTransommountinstallation–routethecableupandoverthe

top edgeof the transom as shown inFigure1-5 . Secure the cable

usingcableclamps (availablefromyour local marineequipment

supplier).
