6.3 Shield connection
•
Cable shields must not be used for current flow.
• A cable shield may not simultaneously assume the function of an N or PE conductor.
• Attach the cable shields always in a large surface.
• Do not create lengthening of the cable shield by unshielded wire connections to the
grounding point. This reduces the shielding effect by up to 90%.
• Connect the cable shield directly after the entry of the cable in the cabinet system
to an earthing bar.

6.4 connection protective earth
• The cabinet system must be connected to the protective earth at destination.
• Use a protective earth conductor which corresponds at least the half cross-section
of the cables for the supply of the power terminals.
• A marked earthing bar is available in the cabinet system for the connection of the
protective earth conductor.
• Another marked earthing bar is available for the connection of the motor protective
earth.
•
The resistance of the protective earth should be 0.1 Ω or less.
• In accordance with EN 61800-5-1, the minimum cross-section of the protective
earth conductor must comply with the local safety regulations concerning protec-
tive earth conductor with high leakage current.
