Minimum clearances and cooling provisions, page 82
Secure the generator with at least four mounting
screws (minimum M12 or comparable, bolt grade
min. 8.8). The attachment must be permanent
and resistant to shock and vibrations. Use
suitable means to prevent the screws from
coming undone by themselves, e.g. via a tension
ring according to DIN 128.

Tightening torque for mounting screws: M =
87 Nm
