Selecting the power cables
General rules
Dimension the supply (input power) and motor cables
according to local
regulations
.
• The cable must be able to carry the drive load current. See the chapter
for the rated currents.
• The cable must be rated for at least 70
°
C (US: 75 °C [167 °F]) maximum
permissible temperature of conductor in continuous use.
• The conductivity of the PE conductor must be equal to that of a phase conductor
(ie. same cross-sectional area).
• 600 VAC cable is accepted for up to 500 VAC.
• Refer to the chapter
for EMC requirements.
Symmetrical shielded motor cable must be used (see the figure below) to meet the
EMC requirements of the CE and C-tick marks.
A four-conductor system is allowed for input cabling, but shielded symmetrical cable
is recommended. Compared to a four-conductor system, the use of symmetrical
shielded cable reduces electromagnetic emission of the whole drive system as well
as motor bearing currents and wear.
The motor cable and its PE pigtail (twisted shield) should be kept as short as
possible in order to reduce electromagnetic emission.
Alternative power cable types
Power cable types that can be used with the drive are represented below.
Symmetrical shielded cable: three phase conductors and
a concentric or otherwise symmetrically constructed PE
conductor, and a shield
Motor cable

Note:
A separate PE conductor is required if the
conductivity of the cable shield is not sufficient for the
purpose.
A four-conductor system: three phase conductors and
a protective conductor.
