Each DISTRIBUTION BOX and controller must be grounded. On the US market, a 5.26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used.
Repeated grounding can be grounded directly from the neutral line or from the housing of the zeroing device. It looks like two lines, and in fact they are
In general, communications cable shields are grounded at one end to prevent ground loop potentials and the associated noise. In cases where equipment designs require grounds at both ends,
