Grounding method: connect the B end of the grounding cable to the grounding terminal block (see Fig. 2-7. For
grounding terminal blocks of other accessory cards and options, refer to the corresponding sections of 2.1), and you can
check the grounding cable diameter and torque by referring to Table 2-1; then connect the A end of the grounding cable
to the grounding rack PE (the mark for grounding, circled in Fig. 2-6) of the drive (taking enclosure B as an example), and
you can check the grounding screw specifications and torque by referring to Table 2-2.
