Separating the device in an uninstalled state
As an alternative, dismount the device completely and separate the control unit and
computer unit from one another in an uninstalled state. So that the processing unit, which is
swung away from the control unit, does not bend the lugs (4), place a surface under the
processing unit.

Remount the device

Installing the device
To reinstall the device, follow the reverse procedure.
Caution
When you swing the control unit and processing unit together, make sure that the flatband
cables are correctly folded together and do not get squished.
In order to do this, fold the flatband cables gently with specific spacing, as shown. The
spacing is shown in the following table. The USB cable does not have to be folded because
it stored as a loop in the processing unit.
