Cap. 2 - Instalation
2.1
Safety rules
As the working voltage and current inside the system is very high, the following rules must be taken into account
to ensure your personal safety:
1 – Only qualified tchnicians who have EV charging training can install the system. During the installation always
observe the safety precautions mentioned in this document and all National Safety Standards.

Then check the equipment serial number, packaging, quantity, acessory types to sure they are compliance.
•
Cable preparation.
Cable selection must be in accordance with national regulations. We recommend using RVVZ type cables as AC
cables with the rated voltage of 550 / 750 Vac or higher and a minimum temperature of 70ºC. Technicians / users
determine a sectional area of the charger input and output cables according to table 2-1

.
The ground cable cross-section should be consistent with the most power distribution cables, but not less than
35mm

. The screw on the ground bus is the M8.
Note:
It is not usual to use a separate ground wire. Normally 5W standard cables (3Ph + N + PE) are used as
show in picture 2.3. the diagram on page 25 should be updated to be in line with the arrangement of the AC input
