Siemens SINAMICS V90 Operating Instructions Manual page 83

Death or severe personal injury from electrical shock
The earth leakage current for the drive can be greater than AC 3.5 mA, which may cause
death or severe personal injury due to electrical shock.
A fixed earth connection is required to eliminate the dangerous leakage current. In addition,
the minimum size of the protective earth conductor shall comply with the local safety
regulations for high leakage current equipment.
Adjusting cable orientations from the motor side
For the low inertia motors with shaft-height of 50 mm and high inertia motors, you can adjust
the orientation of the power cable, encoder cable, and brake cable from motor side to
facilitate cable connection.
Note
Rotating the connectors
All the three motor-side connectors can be rotated only within 360°.
