58 Guidelines for planning the electrical installation
 Alternative power cable types
The recommended and not allowed power cable types to be used with the drive are
presented below.

Power cable types for restricted use
Not allowed power cable types
 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 on page
55, or IEC 61800-5-1. 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
concentric layer of copper wires with an open helix of copper tape or copper wire. The
better and tighter the shield, the lower the emission level and bearing currents.
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. The shield must meet the requirements of IEC 61800-5-1,
see section Motor cable shield on page 58. 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 61800-5-1, see section Motor cable shield on
page 58.
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 section Motor cable shield on page 58.
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.
