2.9.1 Overvoltage protection for large distances or external lines
 When laying lines outside buildings or across large distances, suitable overvolt-
age measures must be implemented. These measures are especially crucial for
bus lines.
 Lines laid outdoors must have shielding with an appropriate power line capacity
and must be earthed at both ends.
 The overvoltage conductor should be installed at the control cabinet entry point.
