WABCO TAILGUARD - Electrostatic Discharge (ESD) and Cable Safety

7
Safety information
Avoid electrostatic charge and uncontrolled discharging (ESD):
Noteduringconstructionandbuildingthevehicle:
 Preventpotentialdifferencesbetweencomponents(e.g.axles)andthe
vehicleframe(chassis).
 Makesurethattheresistancebetweenmetallicpartsofthe
componentsandthevehicleframeislessthan10ohms.
 Establishanelectricallyconductiveconnectionbetweenmovingor
insulatedvehicleparts,suchasaxles,andtheframe.
 Preventpotentialdifferencesbetweenthetowingvehicleandthetrailer.
 Makesurethatanelectricallyconductiveconnectionismadebetween
metalpartsinthetowingvehicleandthecoupledtrailerviathecoupling
(kingpin,fthwheel,clawswithpins),evenwithoutacablebeing
connected.
 Useelectricallyconductiveboltedconnectionswhenfasteningthe
ECUstothevehicleframe.
 Runthecablewithinmetalliccasingswherepossible(e.g.insidethe
U-beam)orbehindmetalandgroundedprotectiveplatingtominimise
theinuenceofelectro-magneticelds.
 Avoidtheuseofplasticmaterialsiftheycancauseelectrostatic
charging.
Whilecarryingoutrepairorweldingworkonthevehicle,observethe
following:
 Disconnectthebattery(ifinstalledinthevehicle).
 Disconnectcableconnectionstodevicesandcomponentsandprotect
connectorsandportsagainstcontamination.
 Alwaysconnectthegroundingelectrodedirectlywiththemetalnextto
theweldingpointwhenweldingtopreventmagneticeldsandcurrent
owviathecableorcomponents.
 Makesurethatcurrentiswellconductedbyremovingpaintorrust.
 Preventheatinuencesondevicesandcablingwhenwelding.
