*1: Please isolate analog output cables from other power cables.
*2: If the ripple voltage of the input terminal of the load connected is large, and results in interference with the
wiring, please connect a 0.1~0.47
μ
F and 25 V capacitor.
*3: If there is much noise, please connect the terminal FE to the ground terminal.
*4: Please connect the ground terminal on a power supply module and the analog output terminal FE to the
system ground, and then ground the system ground or connect the system ground to a distribution box.
