Safety Precautions Safety Precautions Be sure to read carefully this safety precaution given in data sheet and user’s manual before operating the module and follow them. The precautions explained here only apply to the G3F-AD3A, G4F-AD3A, and G6F-AD2A. For safety precautions on the PLC sys tem, please see the MASTER-K 200S/300S/1000S User’s manual and the GLOFA GM3/4/6 User’s manual.
Safety Precautions 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 module. Fasten the terminal screws firmly to the defined torque.
