adjustable frequency inverter, or solely via cable shield, is not permitted as a
protective conductor connection. The filter must be solidly and permanently
connected with the ground potential so as to preclude the danger of electric shock
upon touching the filter if a fault occurs.
To achieve a protective ground connection for the filter:
• • • • Ground the filter with a conductor of at least 10 mm
• • • • Connect a second grounding conductor, using a separate grounding terminal
parallel to the protective conductor. (The cross section of each single protective
conductor terminal must be sized for the required nominal load.)
