For CE compliant installations and installations where EMC emissions must be
minimized, see "Effective Motor Cable Screens" below.
Drive's Motor Connection Terminals
The drive's motor and input power terminals have the same specifications. See
"Drive's Power Connection Terminals" above.
Motor Cable Requirements for CE Compliance
The requirements in this section apply for CE compliance.
Minimum Requirement (CE )
The motor cable must be a symmetrical three conductor cable with a concentric PE
conductor or a four conductor cable with a concentric shield, however, a symmetrical
constructed PE conductor is always recommended. The following figure shows the
minimum requirement for the motor cable screen (for example, MCMK, NK Cables).

Recommendation for Conductor Layout
The following figure compares conductor layout features in motor cables.
Symmetrical shielded cable: three phase
conductors and a concentric or otherwise
symmetrically constructed PE conductor, and a
shield
Not allowed for motor cables (CE )
A four-conductor system: three phase
conductors and a protective conductor, without a
shield.
Effective Motor Cable Screens
The general rule for cable screen effectiveness is: the better and tighter the cable's
screen, the lower the radiated emission level. The following figure shows an
