ACS/ACC/ACP 604/607 DrivesACx=ACS/ACC/ACPC-3Appendix C – IEC InstallationIEC Installations This appendix is a supplement to Chapter C – Electrical Installation. Itcontains additional information to be used in IEC installations. Forinstallations requiring CE compliance, refer also to the section entitledCE Marking in Appendix A.Power Cables Symmetrical shielded motor cable must be used (figure below).Four-conductor system is allowed for mains cabling, but shieldedsymmetrical cable is recommended. To operate as a protectiveconductor, the shield conductivity must be at least 50 % of theconductivity of the phase lead.Compared to a four-conductor system, the use of symmetrical shieldedcable reduces electromagnetic emission of the whole drive system aswell as motor bearing currents and wear.Compared to a four-conductor system, the use of symmetrical shieldedcable reduces electromagnetic emission of the whole drive system aswell as motor bearing currents and wear.The motor cable and its PE pigtail should be kept as short as possiblein order to reduce electromagnetic emission as well as capacitivecurrent.Alternative Power CableTypesPower cable types that can be used with ACx 600 are representedbelow.Symmetrical shielded cable: three phase conductorsand a concentric or otherwise symmetricallyconstructed PE conductor, and a shieldRecommendedPE conductorand shield Shield ShieldA separate PE conductor is required if the conductivityof the cable shield is < 50 % of the conductivity of thephase conductor.A four-conductor system:three phase conductorsand a protectiveconductor.ShieldPEPEPENot allowed for motor cables larger than10 mm 2 (motors > 30 kW).Not allowed for motor cables
