1. For connection of low level analog signals, which are easily
affected by external interference, the wiring length should be
as short as possible (less than 20 m), shielded cables must
be used.
2. Use twin contacts to handle low level signals if contacts are
used in the circuit. In addition, do not ground the GND termi‐
nal.
3. Incorrect operation may occur due to interference on the an‐
alog signal. In such cases, connect a capacitor and ferrite
core at the side of output of the analog signal, as shown be‐
low.
