3. EARTHING MODULE
For the right earthing and the optimal functioning of the module, connect itself to the earth through copper
cables having at least a 16 mm2 cross-section.
To avoid possible side effects, the earth references of the connection and power supply cable of the
indicator and of the connected instrument must be at the same potential.
GENERAL NOTES:
- Use Earth plate of suitable length, in order to obtain a total resistance of earthing plant lower
than 1 Ω.
- One should check and remove, if necessary, the connection between the earth and the neutral
wire of the electrical installation.
