  • Page 2 SAFETY PRECAUTIONS 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 high-speed counting module. For safety precautions on the PLC system, see the GLOFA PLC GM3/4/6 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.
