IEC 60950 (UL 1950) or equivalent, able to guarantee a common mode current or leakage current (see IEC 478/1, CEI 22/3) of no more
than 3.5mA, IEC 60364-41 and CEI 64-8.
U) The shield of the connection cable must be earthed on the circuit-breaker side only. The connection must be made with shielded two-wire
cable (the BELDEN 3105A type) no more than 15 meters in length.
Z) Short-circuit T5 and T6 if the outside neutral current sensor (UI/N) is not connected.
