*1: Please isolate analog input cables from other power cables.
*2: If current is connected, the connection between V3+ and I3+ need to be a short circuit.
*3: If ripple voltage results in interference with the wiring, please connect a 0.1~0.47
μ
F and 25 V capacitor.
*4: If there is much noise, please connect the terminal FE to the ground terminal.
*5: Please connect the ground terminal on a power supply module and the analog input terminal FE to the
system ground, and then ground the system ground or connect the system ground to a distribution box.
