1 Scope
This part of lEC 61851， together with part 1, gives the requirements for a.c. electric vehiclecharging stations for conductive connection to an electric vehicle，with a.c. supply voltagesaccording to lEC 60038 up to 69o v.
This standard does not cover all safety aspects related to maintenance.
The scope of this part of lEC 61851 does not cover box type assemblies with socket-outlets,installed for the purpose of delivering energy to the vehicle，which have no charging controlfunctions.
