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.
