ADDITIONAL MATERIAL REQUIRED FOR INSTALLATION (NOT SUPPLIED)
Supply power wire A:
Multipolar electric wire. Size and length of the suggested electric wire are showed on table “electrical data”. The wire
must be Mod. H07RN-F (according to CEI 20-19 CENELEC HD 22). Make sure the length of the conductors between
the fixing point and the terminals allows the straining of the conductors L, N before that of the grounding.
Connecting wire B (SHIELDED):
Bipolar electric shielded wire; size and length of the suggested electric wire are showed on table “electrical data”.
The wires have not to be lighter than Mod. H05VVC4V5-K (according to CEI 20-20 CENELEC HD21).
Connecting wire C (with ground conductor):
Multipolar electric wire; size and length of the suggested electric wire are showed on table “electrical data”. The
wires have not to be lighter than Mod. H07RN-F (according to CEI 20-19 CENELEC HD22).
