Guidelines for planning the electrical installation 65
Alternative power cable types
The recommended and not allowed power cable types to be used with the drive are
presented below.
Recommended power cable types
Power cable types for restricted use
Not allowed power cable types
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. The shield must agree with the requirements of
IEC 61439-1. 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
agree with the requirements of IEC 61439-1.
Symmetrical shielded cable with three phase conductors and symmetrically
constructed PE conductor, and a shield. The PE conductor must agree with 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.
