Maximum cable lengths

The table below provides an overview of the maximum permissible cable lengths for signal
and supply cables, power cables, and DC link cables.
Note
Total cable lengths for Line Modules
For data regarding maximum total cable lengths of Line Modules and general conditions for
maintaining the corresponding radio interference suppression category, see Chapter
Combination options of Line Modules with line reactors and line filters (Page 135).

For longer lengths, users must connect suitable protective circuitry in order to provide surge voltage protection (refer to
1)
Chapter "24 V DC supply/surge voltage protection").
To comply with EMC limit values, shielded cables (preferably MOTION-CONNECT cables) must be used.
