  This section provides general precautions for using the Programmable Controller (PC) and related devices. The information contained in this section is important for the safe and reliable application of the Programmable Con- troller. You must read this section and understand the information contained before attempting to set up or operate a PC system.

• Page 15: Intended Audience

  WARNING It is extremely important that a PC and all PC Units be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PC System to the above-mentioned applications.

• Page 16: Operating Environment Precautions

  When connecting a personal computer or other peripheral device to the CPM1A, either ground the 0 V side of the CPM1A or do not ground at all. Depending on the method of grounding, the 24-V power supply may short-circuit; do not ground the 24-V side as shown in the following diagram.

• Page 17: Application Precautions

  Always heed these precautions. Failure to abide by the following precautions could lead to serious or possibly fatal injury. • Always connect to a ground of 100 Ω or less when installing the Units. Not con- necting to a ground of 100 Ω or less may result in electric shock.
