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. Voltage spikes are dissipated
over the metallic housing of a RJ45 connector. Noise is conducted over the control cabinet
without additional measures needed on the circuit board of electronic components. To
avoid error sources with data exchange, it is recommended that shielding be placed before
any electronic components in the control cabinet.
