3)
In the USA, aluminum cables must not be used.
4)
The cable sizing is based on NEC Table 310-16 for copper wires, 75 °C (167 °F) wire insulation at 40 °C
(104 °F) ambient temperature. Not more than three current-carrying conductors in raceway or cable or
earth (directly buried). For other conditions, size the cables according to local safety regulations,
appropriate input voltage and the load current of the drive. See also page
of the drive.
Note: For ambient temperatures above +40 °C (+104 °F), the power cables must be
rated for 90 °C (194 °F) minimum.

Alternative power cable types

The recommended and the not allowed power cable types to be used with the drive
are presented below.

Power cable types for limited use

PE
PVC
Symmetrical shielded cable with three phase conductors and a
concentric PE conductor as the shield. The shield must meet the
requirements of IEC 61800-5-1, see page 61. 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 61800-5-1,
see page 61.
Symmetrical shielded cable with three phase conductors and
symmetrically constructed PE conductor, and a shield. The PE conductor
must meet the requirements of IEC 61800-5-1, see page 61.
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).
WARNING! Do not use unshielded single core cables for drives
on IT (ungrounded) networks. A dangerous voltage can become
present on the nonconductive outer sheath of the cable. This can cause
injury or death.
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
Not allowed in the USA.
