5.3 connection of the shield connection
• Cable shields must not be used for power supply.
• A cable shield must not simultaneously assume the function of a N- or PE conductor.
• Always ground the cable shields by means of large surface.
• Do not make extensions 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 control cabinet to
an earthing bar.
5.4 connection of the protective earth
• The drive converter or the control cabinet wherein the drive converter is installed
must be connected to the protective earth at destination.
• Use a protective earth conductor which corresponds at least to the half cross-sec-
tion of the cables for the supply of the power terminals.
• An earthing stud is available at the drive converter for the connection of the motor
protective earth.
•
The resistance of the protective earth should be 0.1 Ω or less.
• The minimum cross section of the protective earth conductor must comply with the
local safety regulations concerning protective earth conductor for high leakage cur-
rent equipment in accordance with EN 61800-5-1.
