Take into consideration this section before starting
wiring the connections of the Charge Point.
1 — E L E C T R I C A L P R O T E C T I O N S
The Charge Point has internal electrical protections, which are installed in each socket for
the protection of the user against electrical faults in accordance with the international
standard IEC 61851-1:2017. These include a three-phase, 4-pole, 40 A type A residual current
device (RCD) with 30 mA sensitivity and additional DC leakage protection of 6 mA; or three-
phase, 4-pole, 40 A type B with 30 mA sensitivity. And a three-phase, 40 A, 4-pole, three-
phase overcurrent device (MCB). In addition to being curve C and class 3.
The chargers equipped with Type A RCDs require an additional RCD installed upstream in
order to ensure the whole installation is compliant with the standard IEC 60364-7-722. This
RCD shall be of Type B or Type A with additional protection for DC leakage of 6mA (RCD-DD)
according to the IEC 62955.
In order to guarantee the total protection of the users and the installation (power supply line
included) in front of any electrical hazard, it is mandatory to install a main circuit breaker
(MCB) and a residual current device (RCD) upstream of the charger. These electrical
protections and the rest of the installation have to be aligned with the local and national
rules. The selectivity of the protections has to be guaranteed at all times.

The dimensioning of the input power supply line of the Charge Point shall be checked by
a qualified electrician. Note that various factors such as cable length between distribution
board and Charge Point and maximum output current of the Charge Point may have
influence on the selected cable. In such cases, increasing the cable cross-section is
required to adapt the temperature resistance of the power supply line.
3 — M A X I M U M O U T P U T C U R R E N T
Please refer to the TECHNICAL DATA section to consult the default factory settings of
maximum output current of the Charge Point. If the power supply is less than maximum
output current and adjustment to a lower nominal current needs to be performed, please
refer to the USER MANUAL.
Depending on the model this value may vary.
