3) Description of Connection of control terminals:
A. Analog input terminal:
Since the weak analog voltage signal is easy to suffer external
interferences, it needs to employ shielded cable generally and the length shall
be no longer than 20 meters, as shown in Fig. 3-8. In case the analog signal
is subject to severe interference, and analog signal source side shall be
installed with filter capacitor or ferrite magnetic core, as shown in Fig.3-9.
