Should There Be Distance Between Profibus And Power Cables? |
|
Answer» YES, even PROFIBUS can get disturbed by interference caused by parallel high voltage power lines. Always try to have at least 10 cm air space between the cables (depends on the level of the voltage). Most users mix all cables in one cable tray and that OFTEN leads to unreliable behaviour. Cables that CROSS each other will not CAUSE problems. Creating distance is not the only REQUIREMENT. CORRECT shielding is also a must.
