￭ Other regions
The disconnecting device must conform to the applicable local safety regulations.
Checking the compatibility of the motor and drive
Use an AC induction motor or permanent magnet motor with the drive. Several induction
motors can be connected to the drive at a time but only one permanent magnet motor can
be connected to the drive at a time. Check that the motor and the drive are compatible
according to the rating table in section
Ratings (page 111) . The table lists the typical motor
power for each drive type.
Selecting the power cables
￭ General rules
Select 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 (page 111) for the rated currents.
• The cable must be rated for at least 70 °C maximum permissible temperature of
conductor in continuous use. For US, see
Conduit (page 55) .
• The conductivity of the PE conductor must be sufficient, see the table below.
• 600 V AC cable is accepted for up to 500 V AC.
To comply with the EMC requirements of the CE mark, use one of the approved cable types
in section
Recommended power cable types (page 54) .
Symmetrical shielded cable reduces electromagnetic emission of the whole drive system
as well as the stress on motor insulation, bearing currents and wear.
The protective conductor must always have an adequate conductivity. The table below
shows the minimum cross-sectional area related to the phase conductor size according to
IEC 61439-1 when the phase conductor and the protective conductor are made of the same
metal.

See the IEC/EN 61800-5-1 requirement on grounding in the Note on section Grounding .
￭ Typical power cable sizes
The table below gives copper cable types with concentric copper shield for the drives with
nominal current. The value separated by the plus sign means the diameter of the PE
conductor.
