Subject to certain conditions, several pulsed resistor modules can be connected
in parallel (refer to Chapter C.1.1, Table 1-4).
The drive bus length may not exceed 11 m.
For more than six modules, control units, round cables must be used (refer to
Chapter 2.1.2).
The equipment bus cable that is looped–through a drive group at an infeed or
monitoring module may not exceed 2.1 m from the supply connection point. For
a two–tier configuration, two equipment bus branches are possible, each with a
maximum length of 2.1 m from the branch point at the supply connection point.
The permitted cable lengths depend on the used line filters, refer to the line fil-
ters in Section 7.4.
