3. Fasten all screws with the specified torque (Tab. 5.1
on page 29).
4. There are six or eight tapped holes on the rotor for
continuing the shaft train mounting. Again use screws
of property class 10.9 or 12.9 and tighten them with
the prescribed torque, as specified in Tab. 5.1.
Important
Use a threadlocker (medium strength, e.g. LOCTITE) to
glue the screws into the counter thread to exclude pre
stressing loss due to screw slackening, in the event of
alternating loads.
Note
Comply with the maximum thread reach as per Tab. 5.1.
Otherwise significant measurement errors may result
from torque shunt, or the transducer may be damaged.
