12.3 Shielding for Wiring Within the Control Cabinet
Sources of strong electromagnetic noise located within the control cabinet (drives, Trans-
formers, etc.) can induce interference in a VARAN bus line. Spike voltages are dissipated
over the metallic housing of a RJ45 connector. Noise is conducted through the control cabi-
net housing without further action from the electronic components. To eliminate sources of
noise during data transfer, it is recommended that the shielding for all electronic compo-
nents be connected within the control cabinet.
