3.2.1 Wiring precautions

① Separate AC and external input signal of A/D module wiring not to be affected by

surge or induced noise in the AC.

② External wiring has to be at least AWG32 (0.3mm

), and be selected in consideration

of operating ambiance and/or allowable current.

③ Separate wiring from device and/or substances generating intense heat, and oil not to

make short-circuit which leads to damage and/or mis -operation.

④ Be careful not to connect external power supply with wrong polarity.

⑤ Separate external wiring sufficiently from high voltage and power supply cable not to

cause induced noise or malfunction of module.
