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 with the drive. Several induction motors 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
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
• The cable must be rated for at least 70 °C maximum permissible temperature of
conductor in continuous use. For US, see
• 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
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.
