Installing The Device In Hazardous Locations - Siemens RUGGEDCOM RX1400 Installation Manual

Chapter 2
Installing the Device
Follow these recommendations for copper data cabling in high electrical noise environments:
• Data cable lengths should be as short as possible, preferably 3 m (10 ft) in length. Copper data cables should
not be used for inter-building communications.
• 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.
