*1. Use shielded cables to isolate the analog input signal cable from other power cables.
*2. If the module is connected to a current signal, the terminals Vn and In+ (n=1–4) must be short-circuited.
*3. If variability in the input voltage results in interference within the wiring, connect the module to a capacitor
with a capacitance between 0.1–0.47 μF and a working voltage of 25 V.
*4. Connect the shielded cable to the terminal FE.
*5. Connect the terminal
*6. Every channel can operate with the wiring presented above.
