4.4 Special attention should be paid to the ground cable
The ground impedance must be lower than 20 ohms in dry weather to ensure
proper system operation. An earthing greater than 20 ohms load can cause
unwanted stops.
There should be an equipotential bond between the terminal and ground of the
electricity supplier.
There should also be an equipotential with any metal object located near the
charger.
4.5 Special attention to the need for a surge arrester
The presence of a surge arrester to protect the charger power line is the responsibility of the installer.
Indeed, the presence and selection of the material must be adapted and in compliance with the
regulations and standards in force in the countries where the charger is installed.
