3.2.1 Wiring precautions
Separate AC and external input signal of A/D module wiring not to be affected by
surge or induced noise in the AC.
External wiring has to be at least AWG32 (0.3mm
2
), and be selected in consideration
of operating ambiance and/or allowable current.
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.
Be careful not to connect external power supply with wrong polarity.
Separate external wiring sufficiently from high voltage and power supply cable not to
cause induced noise or malfunction of module.
