Supply power wire A:
Multipolar electric wire; the size of the suggested electric wire is shown on table. 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; the size of the suggested electric wire is shown on table. The wires have not to
be lighter than Mod. H05VVC4V5-K (according to CEI 20-20 CENELEC HD21).
Connecting wire C / D:
Multipolar electric wire; the size of the suggested electric wire is shown on table. The wires have not to be
lighter than Mod. H07RN-F (wire C) / H05RN-F (wire D), according to CEI 20-19 CENELEC HD22).
