Ground Connection
There are threaded holes for the ground connection on the faces of the
stator. Use a ring terminal to fasten the ground wire one of the threaded
holes.
You can find further details on the exact position of the threaded hole
and their threads in chapter 5, “Dimension sheets” of the particular
motor. The minimum cross-section depends on the particular motor type.
The corresponding data are given in Fig. 8-2.
Note: The indicated minimum cross-section for the power wires is
also valid for the ground wire and must be observed.

Proceed as follows:
1. Clean the contact surface for the bolt head. The surface has to be
metallic bright that the spindle housing and the stator are grounded.
2. Attach the ring terminal of the ground conductor with a brass screw
(M6 or M8, depending on the stator type) to the face of the stator.
3. Grease the connection with Vaseline to protect it from corrosion.
