3.2.2 Differingrequirementsforcompliancewith"Z.E.Ready®"(Renault)
● Forthecasewheretheinternalswitchingelement(contactor)isnolongerabletoopen,anadditional
switchoffcapabilitymustberealized.ThiscanberealizedwiththeswitchcontactoutputX2(fordetails,
seeChapter"4.5.4Switchcontactoutput[X2](excludingeseries)").
● No13Achargingcablesmaybeused.
● For3phaseconnectionoftheKeContactP20,atleastafaultcurrentcircuitbreaker(FI)typeAwithDC
faultcurrentdetection(>6mA)orafaultcurrentcircuitbreaker(FI)typeBmustbeused.
● Renaultrecommendsselectingthefaultcurrentcircuitbreakeraccordingtothefollowingtable:

Thenominalcurrentoftheselectedcircuitlinebreakermayneverexceedthespecificationsonthe
typeplate.Ifthecurrentspecificationandnominalcurrentofthecircuitlinebreakerareequal,the
temperatureintheswitchcabinetmustbespecificallyobserved(thermalderatingofthecircuitline

Mainssupplyrequirements
● InTTandTNnetworks,thegroundingresistanceofthesystemmustbelessthan150Ohm.
● InITorTTnetworkswithagroundingresistancegreaterthan150Ohm,anisolatingtransformermust
beinstalledbeforetheEVSE(ElectricVehicleSupplyEquipment)installation.Theisolatingtransformer
mustthenbeintegratedintoaTNgroundingsystem,applicablefortheabovestatedcriteria.
● PowersupplieswithITgroundingsystemsareforbidden.
● InTTandTNnetworks,thevoltageattheNlinetoPEmaynotbehigherthan10V.
● Anexcessivefractionofharmonicwavescancauseterminationofthechargingprocedure.Thepublic
mainspowersupplyshouldfulfillthestandardsIEC6100021,IEC6100022,EN50160§4.2.4and§
4.2.5topreventthisproblem.Themaximumpermittedlimitofharmonicwavescanvaryindependence
onthemainsnetworkimpedance.
