5. Wiring
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 receive an electrical shock or the unit may be
damaged.
•
As to loads, such as a connector for normal rotation and a connector for reverse rotation,
which are dangerous when turning on at the same time, make sure to interlock them outside
the PLC in addition to interlocking of them in a program in the PLC.
•
Correctly connect the power cable of the FX
2N
-2LC and the PLC as described in this manual.
If the AC power supply is connected to a DC I/O terminal or DC power terminal, the PLC may
be damaged.
•
Perform Class D grounding with an electric wire of 2 mm
2
or more to the grounding terminal in the
FX
2N
-2LC and the PLC. However, never perform common grounding with a strong power system.

•
Use the compensating cable
when you use the thermo couple.
•
The temperature sensor must use
three line type.
The resistance of the lead wire is a
little, and use the wire rod without
the resistance difference between
three lines.
