80 Guidelines for planning the electrical installation
on top of the other, ambient temperature 30 °C, PVC insulation, surface temperature 70 °C (EN 60204-1
and IEC 60364-5-52/2001). For other conditions, size the cables according to local safety regulations,
appropriate input voltage and the load current of the drive.
2. 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.

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

Motor cable shield
If the motor cable shield is used as the sole protective earth conductor of the motor, make
sure that the conductivity of the shield is sufficient. See subsection
General rules above, or
IEC 61439-1. To effectively suppress radiated and conducted radio-frequency emissions,
the cable shield conductivity must be at least 1/10 of the phase conductor conductivity.
The requirements are easily met with a copper or aluminum shield. The minimum
requirement of the motor cable shield of the drive is shown below. It consists of a
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. The shield must meet the requirements of IEC 61439-1,
see page
76 . Check with local / state / country electrical codes for allowance.
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. A separate PE conductor is required if the shield does not
meet the requirements of IEC 61439-1, see page
76 .
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.
A four-conductor system (three phase conductors and a protective conductor on
a cable tray) is
not allowed for motor cabling (allowed for input cabling).
Symmetrical shielded cable with individual shields for each phase conductor is
not allowed on any cable size for input and motor cabling.
