2.7. Installation of external protection devices
The product is only equipped with a 6 mA DC direct current detection device. Consequently, in
accordance with the IEC 61851-1 standard, the device must be protected upstream by externally
installing a Miniature Circuit Breaker (MCB) and a Residual current device (RCD).
eProfessional is not fitted with a PEN fault detection system.
MCB:
Recommended C curve, 5kA rated short-circuit capacity. Rated current according to
power supply and charger setting, but no more than 32 A. In the event of a short circuit, the
value of I2t at the vehicle connector of the charging station should not exceed 75000 A2s.
The overcurrent protection devices should comply with IEC 60947-2, IEC 60947-6-2, IEC 61009-1
or the relevant parts of IEC 60898 series or IEC 60269 series.
RCD:
According to local regulations, Type A or Type B. Manual reset type only. The RCD should
have a rated residual operating current not exceeding 30 mA and should comply with one of
the following standards: IEC 61008-1, IEC 61009-1, IEC 60947-2 and IEC 62423. The RCD should
disconnect all live conductors.
SPD:
To prevent potential damage to the electric vehicle caused by overvoltage, we strongly
recommend protecting the power supply circuit of the connection point with an SPD.
IMD:
If installed in IT-type systems, an insulation monitoring device (IMD) compliant with CEI
EN 61557-8 must be fitted.
If installed in TN-type systems, there may be additional specific local regulations
regarding system safety and protection against faults that the installer must
understand and implement. A circuit powering a connection point must not be
included in a PEN conductor in a TN system.
