Follow these recommendations for copper data cabling in high electrical noise environments:
•Data cable lengths should be as short as possible - ideally limited to 3m (10') in length. Copper data cables should not be used for
•Power and data cables should not be run in parallel for long distances, and should be installed in separate conduits. Power and data cables should intersect at 90° angles when necessary to reduce inductive coupling.
