5.2 Electrical installation
5.2.1 Wiring according to EMC guidelines
In typical systems, standard shielding is sufficient for Ethernet cables.
However, in environments with a very high level of interference, EMC resistance can be improved
by additionally earthing the cable shield on both sides.
For this observe the following notes:
1. The distance between the additional earthing and the Ethernet plug 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 cable 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.
