 Precautions on Wiring
• Use double-core twisted-pair shielded wires. It is recommended to ground the shielding.
However, depending on the conditions of the external noise, it may be better not to ground
the shielding.
• Do not have the analog input wiring close to AC wires, power wires, or load wires.
• Do not have the analog output wiring close to AC wires, power wires, or load wires.
