Cautions on Wiring
• Make sure to shut down the power supplies of all phases on the outside before starting
installation or wiring.
If the power supplies are not shut down, you may get electrical shock or the unit may be
damaged.
• As to loads which are dangerous when turning on at the same time, make sure to inter-
lock them outside the PLC and the FX
gram in the PLC.
• Correctly connect the power cable of the FX
manual.
If the AC power supply is connected to a DC I/O terminal or DC power terminal, the PLC
may be burnt.
• Never perform external wiring to unused terminals
Such wiring may damage the units.
• Perform Class 3 grounding with an electric wire of 2 mm
