Note: UL (NEC) installation can include separate insulated conductors inside a conduit,
shielded VFD cable in conduit, or shielded VFD cable without conduit. The normal dashed
symbol (3) in this diagram represents the shield of shielded VFD cable. The same solid
symbol (2) represents conduit.
1 Insulated ground conductor in a conduit: Ground to drive's PE terminal and to the
distribution panel ground bus. For a VFD cable installation, see 4.
Note: If the cross-section of the Cu PE conductor is less than 8 AWG, install a second
Cu PE conductor of the same cross-sectional area as the original PE conductor. Altern-
atively, you can use a Cu PE conductor with at least 10 mm 2 cross-section. See page
26.
2 Conduit ground: Bond the conduit to the drive's conduit box and to the distribution
panel enclosure. For a VFD cable installation, see 3.
3 Shield of a VFD shielded cable: Ground the shield 360° under drive's grounding clamp,
then twist with the ground conductors and connect under the drive's ground terminal.
Ground the shield also 360° at the motor end, then twist and connect under the motor's
ground terminal. For a conduit installation see 2.
4 Symmetrically constructed grounding conductors inside a VFD shielded cable: Twist
together, combine with the shield and connect under the drive's ground terminal and
under the motor's ground terminal. For a conduit installation, see 1.
