PROPER INSTALLATION COMBINED WITH OPERATOR
TRAINING IN THE PROPER USE OF EMERGENCY WARNING
DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF
EMERGENCY PERSONNEL AND THE PUBLIC.
INSTALLATION AND MOUNTING
GENERAL
Alldevicesshouldbemountedinaccordancewiththemanufacturer’sin-
structionsandsecurelyfastenedtovehicleelementsofsufcientstrength
towithstandtheforcesappliedtothedevice.
WIRING
Donotuseinsulationdisplacementconnectors(e.g.3MScotchlocktype
connectors).  Route wiring using grommets and sealant when passing
throughcompartmentwalls.Highambienttemperatures(e.g.under-hood)
willsignicantlyreducethecurrentcarryingcapacityofwires,fuses,and
circuitbreakers.Use“SXL”typewireinenginecompartment.Minimize
thenumberofsplicestoreducevoltagedrop.Allwiringshouldconformto
the minimum wire size and other recommendations of the manufacturer
andbeprotectedfrommovingpartsandhotsurfaces.Looms,grommets,
cableties,andsimilarinstallationhardwareshouldbeusedtoanchorand
protectallwiring.
Particularattentionshouldbepaidtothelocationandmethodofmaking
electricalconnectionsandsplicestoprotectthesepointsfromcorrosionand
lossofconductivity.Groundterminationsshouldonlybemadetosubstantial
chassiscomponents,preferablydirectlytothevehiclebattery.
Theusershouldinstallafusesizedtoapproximately125%ofthemaximum
ampcapacityinthesupplylineandeachswitchedcircuittoprotectagainst
shortcircuits.Forexample,a5ampfuseshouldcarryamaximumof4
amps.Circuitbreakersareverysensitivetohightemperaturesandwill“false
trip”whenmountedinhotenvironmentsoroperatedclosetotheircapacity.
Fusesshouldbelocatedasclose to the vehiclepower takeoffpointsas
possibleandproperlysizedtoprotectthewiringdevices.
