WARNING
With alternating load: Use a screw locking device (e.g. LOCTITE no. 242)
to cement the screws into the mating thread to exclude prestressing
loss due to screw slackening.
3. Tighten all screws with the specified tightening torque (Tab. 4.1).
4. For further mounting of the shaft train, there are tapped holes on the rotor.
Again use screws of property class 12.9 and tighten them crosswise with
the prescribed tightening torque, as specified in Tab. 4.1.
CAUTION
With alternating loads, use a screw locking device to cement the con
necting screws into place. Guard against contamination from varnish
fragments.
