The maximum length of shielded motor cables is 200 m (MR8-MR12).
•
If the cable insulation checks are necessary, see chapter 7.3 Measuring the cable and
motor insulation for instructions.
•
If the motor cables are in parallel with other cables, obey the minimum distances.
•
The distances are also valid between the motor cables and the signal cables of other
systems.
