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. The external wiring precautions are shown below: 1.
