Design recommendations aa the charging unit is pluged into an If existing socket, protected with a Type A RCCB, additional protection against smooth DC residual currents above 6 mA must be provided (IEC 60364-7-722). EFI-P Type A I∆n= 30 mA

aa the charging unit has a fixed If connection, EFI eV will provide complete protection against residual currents.

aa these systems, switch-off times must In comply to stricter rules so even the charging units with fixed connection require a Type A RCCB, which needs to be additionally protected against smooth DC residual currents above 6 mA by EFI eV. EFI-P Type A I∆n= 30 mA

aa more charging units are in use, the first If RCCB must be a Type B device to protect from the sum of all smooth DC residual currents. Each charging plug socket must also be protected with EFI eV.
