4.2 LIMITATION OF THE INDUCED INTERFERENCES ON THE CIRCUIT

• Weave and screen the signal conductors
• Put on the ground to just a one extremity the weak signal conductors screen to a low frequency
• When the weak signal conductors and the noises conductors are in the same connectors, separate them interposing between them the earth connectors.
• Take the signal conductors screen across the connectors on the separated pin.
• Avoid the common earth conductors between the equipments to high level and those a low level
• Keep separated the electrics circuits earth from the metallics structures earth
• Keep the earth conductors as shorter as possible
• Maintain the source and the cargo balanced towards the earth
• Enclose all the sensibles circuits in the screening zones.
• Filtrate or decouple the conductors that entry in the screened bin
• Maintain as shorter as possible the termination conductors of the cables screens
• Avoid the grounding' mash reducing the area to the minimum.
