Planning the electrical installation42Selecting the power cablesGeneral rulesDimension the supply (input power) and motor cables according to localregulations.ï The cable must be able to carry the drive load current. See the chapter Technicaldata for the rated currents.ï The cable must be rated for at least 70 ∞C (US: 75 ∞C [167 ∞F]) maximumpermissible temperature of conductor in continuous use.ï The conductivity of the PE conductor must be equal to that of a phase conductor(ie. same cross-sectional area).ï 600 VAC cable is accepted for up to 500 VAC.ï Refer to the chapter Technical data for EMC requirements.Symmetrical shielded motor cable must be used (see the figure below) to meet theEMC requirements of the CE and C-tick marks.A four-conductor system is allowed for input cabling, but shielded symmetrical cableis recommended. Compared to a four-conductor system, the use of symmetricalshielded cable reduces electromagnetic emission of the whole drive system as wellas motor bearing currents and wear.The motor cable and its PE pigtail (twisted shield) should be kept as short aspossible in order to reduce electromagnetic emission.Alternative power cable typesPower cable types that can be used with the drive are represented below.Symmetrical shielded cable: three phase conductors anda concentric or otherwise symmetrically constructed PEconductor, and a shieldMotor cable(also recommended for supply cabling)PE conductorand shield Shield ShieldNote: A separate PE conductor is required if theconductivity of the cable shield is not sufficient for thepurpose.A four-conductor system: three phase conductors anda protective conductor.ShieldPE PEAllowed for supply cablingPE PE
