58 Planning the electrical installation

Other regions
The disconnecting device must conform to the applicable local safety regulations.
Checking the compatibility of the motor and drive
Use an asynchronous AC induction motor or a 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 on page 134 . 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 134 ) 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 Additional US requirements, page 61 .
• The conductivity of the PE conductor must be sufficient, see the table on page 58 .
• 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 on page 60 .
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.
Note: See the IEC/EN 61800-5-1 requirement on grounding in the Note on page 18 .
