Power supply connection
a.
Cut both the power supply cables to adequate length and add the ferrules to each conductor.
b.
Measure the resistance of the grounding circuit and make sure that it is within acceptable limits.
If necessary, install a grounding point closer to the charging station.
c.
Connect each supply cable to the correct terminal block indicated with L1, L2, L3, N and PE.
Phase rotation
To avoid overloading the first phase with one-phase electric vehicles, phase rotation is
recommended. We recommend rotating the phases as shown in the table below.
