Chapter 3 – Electrical Installation3-22 ACA 6xx Sections and ACS/ACC 6x7 (132 to 3000 kW) Frequency ConvertersConductive Sleeves Conductive sleeves are supplied by ABB as an option to provide 360°high-frequency earthing for motor cables. Follow these instructions:• If fire insulation is used, make an opening to the mineral wool sheetaccording to the diameter of the cable.• Pull the cable into the cabinet through the conductive sleeve.• If a rubber grommet is used, slide it onto the cable.• Connect phase conductors to terminals.• Twist the shield wires of the cable together and connect them to earthterminal or PE busbar.• Peel off 3 to 5 cm of the outer insulation of the cable above the entryplate for the 360° high-frequency earthing.• Fasten the conductive sleeve to the cable shield with a cable tie.• Seal the slot between the cable and mineral wool sheet (if used) withsealing compound (e.g. CSD-F, ABB brand name DXXT-11, code35080082).• Tie up the unused conductive sleeves with cable ties.Cable Entry Cable entry from below for power cables of ACx 600 (IP 21 and IP 22)is shown below. Tighten the EMC sleeve on the stripped part of thecable with cable ties. For IP 54 units, add a rubber grommet on the cable under the lead-through plate.EMC sleeveLead-throughplateStrip this part ofthe cableCable shieldBase platePE terminalStrain relief
