If a shielded cable is used (not required but recommended) and the conductivity of the shield is < 50%
of the conductivity of the phase conductor, use a separate PE cable (2a) or a cable with a grounding
conductor (2b).

ABB recommends 360-degree grounding at the cabinet entry if a shielded cable is used. Ground the
other end of the input cable shield or PE conductor at the distribution board.
