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 mm
2
cross-section.
T av id p ssible side effects, the earth references f the c nnecti n and p wer supply cable f the
indicat r and f the c nnected instrument must be at the same p tential.
GENERAL NOTES:
-Use Earth plate f suitable length, in rder t btain a t tal resistance f earthing plant l wer
than 1 Ω.
-One sh uld check and rem ve, if necessary, the c nnecti n between the earth and the neutral
wire f the electrical installati n.
