Planning the electrical installation
Checking the compatibility of the motor and drive
Check that the 3-phase AC induction motor and the drive are compatible according
to the rating table in section
Ratings on page 137 . The table lists the typical motor
power for each drive type.
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 137 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 US requirements
on page 32 .
• 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 137 for the EMC requirements.
A symmetrical shielded motor cable (see the following figure) 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.
