Measures to ensure EMC-compliant wiring of the Control Unit:
● Use the shield connection kit of the Control Unit to connect the shield and provide strain
relief for cables/conductors.
Shield connection kit 1 for the CU230P-2 Control Units with all fieldbus
interfaces except for PROFINET.

Shield connection kit 3 for the CU230P-2 and CU240E-2 Control Units
with PROFINET interface.
6SL3264-1EA00-0HB0
● If you use shielded cables, then you must connect the shield to the mounting plate of the
control cabinet or with the shield support of the inverter through a good electrical
connection and a large surface area.
