*1. Please use a shielded cable as an analog input cable, and isolate the shielded cable from other power
cables.
*2. If current is connected, the connection between Vn+ and In+ needs to be a short circuit. (n is in the range of
0 to 7.)
*3. If ripple voltage results in interference with the wiring, please connect a 0.1~0.47 μF and 25 V capacitor.
*4. Please connect the ground in the shielded cable to the terminal SG.
*5. Once AH04AD-5A/AH08AD-5A is installed on a backplane, the connection between the terminal SG on
AH04AD-5A/AH08AD-5A and the terminal
terminal on the backplane to the ground terminal
