- Page 2 Be sure to read carefully the safety precautions given in data sheet and user’s manual before operating the module and follow them. The precautions explained here only apply to the G3F-AD4A , G3F-AD4B and G4F-AD2A. For safety precautions on the PLC system, see the GLOFA GM3/4 CPU User’s Manuals and MASTER- K200S/300S/1000S CPU User’s Manuals.
- Page 3 Wiring Precautions CAUTION ▶ When grounding a FG terminal, be sure to provide class 3 grounding which is dedicated to the PLC. ▶ Before the PLC wiring, be sure to check the rated voltage and terminal arrangement for the module and observe them correctly. If a different power, not of the rated voltage, is applied or wrong wiring is provided, it can cause a fire or disorder of the nodule.
