ABB recommends the use of conduit for power wiring to the drive and between the
drive and the motor(s). Due to the variety of application needs, metallic and non-
metallic conduit can be used. ABB prefers the use of metallic conduit. Where
permitted, non-metallic conduit may be used.
The following tables show examples of various materials and methods for wiring the
drive in the intended application. See NEC 70 along with state and local codes for the
appropriate materials for your application.
Yes
WARNING! If you
use unshielded
high-power input power
cables in an IT network,
make sure that the non-
conductive outer sheath
(jacket) of the cables have
good contact with a
properly grounded
conductive surface, for
example, install the cables
on a properly grounded
cable tray. Otherwise
voltage may become
present on the non-
conductive outer sheath of
the cables, and there is
even a risk of an electric
shock.
No
A single-core cable system: three
phase conductors and PE conductor
