By installing angle 1 in different holes on the mounting surface, it is possible to turn the PROFIBUS ILM through the vertical axis, however the adjustment is not continuous.

By loosening the M6 securing bolts, the PROFIBUS ILM can be adjusted continuously to align it to the partner station in the horizontal axis. To add greater stability, it is advisable to use toothed washers with the bolts.

It is also advisable to install the module at the edge of the mounting surface so that the cables lead to and from the module unhindered and to make sure that there is no reflection of the sender to its own receiver caused by the installation site itself.
