SAFETY PRECAUTIONS (Read these precautions before using.) When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in this manual. 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 PC system safety precautions.
[DESIGN PRECAUTIONS] DANGER l Configure a safety circuit external to the PC, so that the entire system operates safely even if there is an external power error or if the PC is malfunctioning. (1) The external output are as shown below, depending on the output status setting in the external-output control setting mode: Please be careful when performing the setting.
[INSTALLATION PRECAUTIONS] CAUTION l Use the PC in the environment given in the general specifications of this manual. Using the PC outside the range of the general specifications may result in electric shock, fire or malfunction, or may damage or degrade the module. l Insert the tabs at the bottom of the module into the mounting holes in the base module before installing the module.
[STARTING AND MAINTENANCE PRECAUTIONS] DANGER l Do not touch the terminal before all phases of the power supply have been obstructed from the outside. It may cause erroneous operation. l Make sure all phases of the power supply have been obstructed from the outside before cleaning the module or retightening the screws.

4. Handling Precaution when handling (1) The module case is made of plastic. Be sure not to drop it or subject it to strong vibration. (2) Do not remove the module printed circuit boards from the case. It may cause trouble. (3) When connecting the wiring, do not allow wire cuttings or other foreign matter to enter from the top of the module.
5. Wiring The precaution when wiring and the module connection example are shown below. Precaution when wiring In order to have the best result from the A1S64TC functions and to make the system highly reliable, an external cabling with low noise effects are necessary.
