Safety Precautions (Read these precautions before using.) 2. INSTALLATION PRECAUTIONS • Make sure to shut down all phases of the power supply externally before installing. Failure to do so may cause electric shock or damage to the product. • Use the product within the generic environment specifications described in PLC main unit manual (Hardware Edition).
Safety Precautions (Read these precautions before using.) • Connect the AC power supply to the dedicated terminals specified in this manual. If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, the PLC will burn out. • Do not wire vacant terminals externally. Doing so may damage the product. • Use class D grounding (grounding resistance of 100Ω or less) with a wire of 2mm2 or thicker on the grounding terminal of the PLC.
Safety Precautions (Read these precautions before using.) 5. DISPOSAL PRECAUTION • Please contact a certified electronic waste disposal company for the environmentally safe recycling and disposal of your device. 6. TRANSPORTATION PRECAUTION • The PLC is a precision instrument. During transportation, avoid impacts larger than those specified in the general specifications of the PLC main unit manual. Failure to do so may cause failures in the PLC. After transportation, verify the operations of the PLC.
