Use a separate grounding PE cable (2a) or a cable with a separate PE conductor (2b)
if the conductivity of the shield does not meet the requirements for the PE conductor

Note: If there is a symmetrically constructed grounding conductor on the motor cable in
addition to the conductive shield, connect the grounding conductor to the grounding ter-
