Also pay careful attention to safety and handle the module properly. These precautions apply only to Mitsubishi equipment. Refer to the CPU module user's manual for a description of the PLC system safety precautions. -
Page 3: Wiring Precautions
[WIRING PRECAUTIONS] CAUTION If there are high levels of noise, ground the AG terminal and FG terminal with Class D grounding (Class 3 grounding) or higher dedicated for the PLC. Failure to observe this could lead to malfunctioning. When wiring in the PLC, be sure that it is done correctly by checking the product's rated voltage and the terminal layout. - Page 4 About the Manuals The following manuals are related to this product.

- Page 11 4. Handling 4.1 Precautions for handling (1) The main body case and terminal block are made of resin, so do not drop them or apply strong impacts. (2) Do not remove the module PCB from the case. Doing so could lead to faults. (3) Make sure that foreign matter, such as wire scraps, does not enter from the top of the module during wiring.
- Page 12 A1S64AD functions to the fullest and creating a highly reliable system. The precautions for external wiring are given below. (1) Use separate cables for the alternating current and A1S64AD external input signals to eliminate the effect of surge or inductance on the alternating current side.
- Page 13 ANALOG *1: Use a 2-core twisted shield wire. *2: Indicates the A1S64AD input resistance. *3: For the current input, always connect with the (V+) and (I+) terminals. *4: If noise or ripple is generated in the external wiring, connect a. 0.1 to 0.47μF capacitor (approximate 25V or more withstand voltage) between the terminal V and COM.
