G-14 ADAM-5510/P31
Grounding Reference
• Shield connection (2)
Above diagram shows you that the fill soldering just makes a easier
way for the signal.
G.3 Noise Reduction Techniques
• Enclose noise sources in shield enclosures.
• Place sensitive equipment in shielded enclosure and away from
computer equipment.
• Use separate grounds between noise sources and signals.
• Keep ground/signal leads as short as possible.
• Use Twisted and Shielded signal leads.
• Ground shields on one end ONLY while the reference grounds are
not the same.
• It’s almost communication problem while system unstable.
• Add another Grounding Bar if necessary.
• The diameter of power apply cable must be over 2.0 mm2.
• Independent grounding is needed for A/I, A/O, and communication
network while using the jumper box.
• Use noise reduction filters if necessary. (TVS, etc)
• You can also refer to FIPS 94 Standard. FIPS 94 recommends that the
computer system should be placed closer to its power source to
eliminate load-induced common mode noise.
