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