Installation Of The Protection Against Residual Current; Overvoltage Protection; Installation Cables; Supported Power Supply Systems - ETI EV PLUS Serie Manuel D'installation

6.4 Installation of the protection against residual current

In compliancy with the IEC 61851-1 standard, the charger contains an appropriate circuit that
ensures the disconnection of the supply in case of DC fault current above 6mA (DC Leak
protection circuit).
No external installation of any type B RCD is prescribed.
An external type A RCD, with supply disconnection in case of fault current above 30mA
shall be installed in the upstream side.
The protection device selection and installation must be performed by qualified
personnel only.

6.5 Overvoltage protection

The charger is compliant to the Overvoltage Category III

6.6 Installation cables

The cable for connecting the mains supply to the charger must have a section in the following
2
range 6-10 mm
The cable selection must be done by the qualified personnel involved in the installation
process, taking into account the national regulations for the safety and the state of the art of
the electrical installations.

6.7 Supported power supply systems

Both single-phase and three-phase chargers support the following power supply systems.
▪ TN-S
▪ TN-C
▪ TN-C-S
▪ TT
▪ IT (only single-phase products are supported)
For single-phase charger, in a power supply system with a neutral line, the voltage between the
phase line and the neutral line cannot be higher than the rated voltage requirement (240VAC).
In a power supply system without a neutral line, the voltage between the phase line and the
phase line cannot be higher than the constant voltage requirement (240VAC).
For three-phase charger, in a power supply system with a neutral line, the voltage between the
phase line and the neutral line cannot be higher than the rated voltage requirement (240VAC).

6.8 Installation steps
