Two protective earth (ground) conductors. Drive safety standard IEC/EN/UL 61800-
5-1 requires two PE conductors if the cross-sectional area of the PE conductor is less
than 10 mm

Cu or 16 mm

Al. For example, you can use the cable shield in addition to
the fourth conductor.
1
Use a separate grounding cable or a cable with a separate PE conductor for the line
side if the conductivity of the fourth conductor or shield does not meet the requirements
for the PE conductor.
2
Use a separate grounding cable for the motor side if the conductivity of the shield is
not sufficient, or if there is no symmetrically constructed PE conductor in the cable.
3
360-degree grounding of the cable shield is required for the motor cable and brake
resistor cable (if used). It is also recommended for the input power cable.

If necessary, install an external filter (d

, common mode, or sine filter). Filters are
available from ABB.

For IP66 (UL Type 4X) drive with optional disconnect, wire to terminals 2T1, 4T2 and
6T3. External disconnect is not needed but external fuses are still required.
