2-core shielded twisted pair cable for the analog input lines, and
arate the analog input lines from other power lines or inductive lines.
grounding resistance should be 100Ω or less.
Grounding
Grounding should be performed as stated below.
• The grounding resistance should be 100Ω or less.
• Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared
grounding" of the following figure.
