Alternative power cable types
The recommended power cable types and the not allowed power cable types to be
used with the drive are presented below.
Recommended power cable types
Power cable types for limited use
Not allowed power cable types
Symmetrical shielded cable with three phase conductors and a
concentric PE conductor as the shield. The shield must meet the
requirements of IEC 61439-1, see page
49 . Check with
local/state/country electrical codes for allowance.
Symmetrical shielded cable with three phase conductors and a
concentric PE conductor as the shield. A separate PE conductor is
required if the shield does not meet the requirements of IEC 61439-1,
see page
49 .
Symmetrical shielded cable with three phase conductors and
symmetrically constructed PE conductor, and a shield. The PE conductor
must meet the requirements of IEC 61439-1, see page
49 .
A four-conductor system (three phase conductors and a protective
conductor on a cable tray) is
not allowed for motor cabling (it is
allowed for input cabling).
A four-conductor system (three phase conductors and a PE conductor in
a PVC conduit) is
allowed for input cabling with phase conductor
cross-section less than 10 mm
2
(8 AWG) or motors < 30 kW (40 hp) .
Not allowed in the USA.
Corrugated or EMT cable with three phase conductors and a protective
conductor is allowed for motor cabling with phase conductor cross
section less than 10 mm
2
(8 AWG) or motors < 30 kW (40 hp).
Symmetrical shielded cable with individual shields for each phase
conductor is not allowed on any cable size for input or motor cabling.
