Wiring according to EMC guidelines
In typical systems, standard shielding is sufficient for the INTERBUS cable.
In environments with very strong interferences, the EMC compatibility can be improved by an
additional earthing of the cable shield.
For this observe the following notes:
1. The distance of the additional earthing of the INTERBUS plug (Sub-D, 9-pole) depends on the
module slot and is as follows ...
• approx 10 cm for the upper slot (MXI1);
• approx. 20 cm for the lower slot (MXI2).
2. Measure the appropriate distance along the cables and, starting from this point, remove 2 cm
of the cable's plastic sheath.
3. Connect the cable shield to the shield sheet of the Servo Drive 9400.
