48 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, permanent magnet motor or synchronous
reluctance motor (SynRM) with the drive. Several induction motors can be connected
to the drive at a time.
Make sure that the motor and the drive are compatible according to the rating table in
section
Ratings on page 88 . The table lists the typical motor power for each drive
type.
Selecting the power cables
Select the input power and motor cables according to the local regulations:
• The input power and the motor cables must be able to carry the corresponding
load currents. Refer to Ratings on page 88 .
• The cable must be rated for at least 70
°
C maximum permissible temperature of
conductor in continuous use. For the US, refer to Additional US requirements on
page 52 .
• The conductivity of the PE conductor must be sufficient, refer to page 49 .
• A 600 V AC cable is accepted for up to 500 V AC.
To comply with the EMC requirements of the CE mark, use an approved cable type.
Refer to
Recommended power cable types on page 51 .
Use a symmetrical shielded cable to decrease:
• The electromagnetic emissions of the drive system.
• The stress on the motor insulation.
• The bearing currents.
The protective conductor must always have an adequate conductivity.
Unless local wiring regulations state otherwise, the cross-sectional area of the
protective conductor must agree with the conditions that require automatic
disconnection of the supply required in 411.3.2. of IEC 60364-4-41:2005 and be
capable of withstanding the prospective fault current during the disconnection time of
the protective device.
The cross-sectional area of the protective conductor can either be selected from the
table below or calculated according to 543.1 of IEC 60364-5-54.
This table shows the minimum cross-sectional area related to the phase conductor
size according to IEC 61800-5-1 when the phase conductor and the protective
conductor are made of the same metal. If this is not so, the cross-sectional area of
