Important
Dry screw connections can result in different and higher friction factors (see
VDI 2230, for example). This means a change to the required tightening
torques.
The required tightening torques can also change if you use screws with a sur
face or property class other than that specified in Tab. 5.1, as this affects the
coefficient of friction.

Installing the stator
On delivery, the stator has already been installed and is ready for operation.
The upper antenna segment can be separated from the stator, for example, for
maintenance or to facilitate stator installation.
