 Ensure that the voltage class of the VFD is consistent with that of the grid.
D.5 Cable
D.5.1 Powe cable
The sizes of the input power cables and motor cables must comply with local regulations.
 The input power cables and motor cables must be able to carry the corresponding load currents.
 The maximum temperature margin of the motor cables in continuous operation cannot be lower
than 70° C.
 The conductivity of the PE grounding conductor is the same as that of the phase conductor, that
is, the cross-sectional areas are the same. For VFD models of higher than 30kW, the cross
sectional area of the PE grounding conductor can be slightly less than the recommended area.
 For details about the EMC requirements, see Appendix B Technical data.
To meet the EMC requirements stipulated in the CE standards, you must use symmetrical shielded
cables as motor cables (as shown in the following figure).
Four-core cables can be used as input cables, but symmetrical shielded cables are recommended.
Compared with four-core cables, symmetrical shielded cables can reduce electromagnetic radiation
as well as the current and loss of the motor cables.
Note: If the conductivity of the shield layer of the motor cables cannot meet the requirements,
separate PE conductors must be used.
To protect the conductors, the cross-sectional area of the shielded cables must be the same as that of
the phase conductors if the cable and conductor are made of materials of the same type. This
reduces grounding resistance, and thus improves impedance continuity.
