Installation Recommendation

Basic rules:

The way line/equipment has to be respected
Imperative connection to earth

Earth connection:

The length of the eath network connection conductro must be as short as possible : inf. to 0,5 m
Minimum section of the earth connection cable : 4 mm²
The protection must be connected to the same earth than the protected equipment
The equipotentiality, between the protection and the protected equipment, must be done by the shortest way

Location:
The protection box, in general, installed at the entrance of the installation (connection box to external network), but regarding these following points:

Respect of the "Equipotentiality" rule
Overvoltage trouble can happen inside the installation (coupling with the AC network..) In these case, an installation near the protected equipment is recommended
