There is a hexagon bolt with a flat washer and a spring washer on the stator frame at the
designated connection point for the grounding conductor. The grounding conductor can be
connected as follows:
● With stranded cables with cable lugs
● With flat cables with cable end designed accordingly
As an alternative, you can connect the grounding conductor without cable lugs using a
clamping plate at the marked connection point.
Connecting the grounding conductor
● Use the connecting terminals designated for the grounding conductor in the terminal box.
● Ensure that the connecting surface is bare and is protected against corrosion using a
suitable substance, e.g. acid-free Vaseline.
● Arrange the flat washer and spring washer under the screw head.
● Check that the maximum permissible clamping thickness of 10 mm for the cable lug or strap
is not exceeded.
● Fasten the clamping screw according to the following table. Screw-in depth and tightening
torque are different depending on whether cable lugs or ground terminals are used.
