The bus cable must not be
½ twisted
½ stretched or
½ compressed
during installation. Supplementary constraints as regards electromagnetic
compatibility must also be observed.
Further relevant information can be found, for example, in Chapter 3 of the
Compendium (6SE7080-0QX50 Edition AE, MASTERDRIVES Docu).
