Planning the electrical installation 37
Selecting the power cables
 General rules
Dimension the input power and motor cables according to local regulations.
• The input power and the motor cables must be able to carry the corresponding
load currents. See section Ratings on page 384 or in section Definitions on page
385 for the rated currents.
• The cable must be rated for at least 70 °C maximum permissible temperature of
the conductor in continuous use. For US, see section Additional North American
requirements on page 39.
• The conductivity of the PE conductor must be equal to that of the phase
conductor (same cross-sectional area).
• 600 V AC cable is accepted for up to 500 V AC.
• Refer to chapter Technical data on page 383 for the EMC requirements.
A symmetrical shielded motor cable (see the figure below) must be used to meet the
EMC requirements of the CE and C-Tick marks.
A four-conductor system is allowed for input cabling, but a shielded symmetrical
cable is recommended.
Compared to a four-conductor system, the use of a symmetrical shielded cable
reduces electromagnetic emission of the whole drive system as well as motor bearing
currents and wear.
