ELECTRICAL INSTALLATION

Grid Connection

Observations

• The short-circuit current at the connection point cannot exceed 10 kA.

• The impedance of the loop with respect to ground must not exceed 80 Ω.

• This connection must be protected, in a previous phase (main electrical panel where the

supply comes from), by a four-pole magnetothermic switch (moulded case), minimum of

100 A; type curve D, by a differential switch capable of withstanding at least the maximum

current of the previously mentioned switch, with a sensitivity of 300 mA; type A.

• The overvoltage protection of 20% Vn (Nominal Voltage) will be necessary.

• The dimensions of the wiring must comply with the regulations

and standards in force in the country of installation.

• To calculate the minimum section, remember that the fast

charger has a maximum primary winding current of 130 A.
