6.4.3. Grounding the drive and the motor (multi-point bonding)

Multi-point bonding is the preferred method for voltage source converter applications.
NOTE – Multi-point bonding is not allowed for high-speed applications; use single-point
bonding instead (see Section 6.4.4, "Grounding the drive and the motor (single-point bonding)",
page 89).
For more information, see "Power cables engineering guideline", 3BHS542290 E01.
Fig. 53 shows the multi-point connections for grounding a drive and a motor in the
COU compartment.
