4.2.4 Wiring
 Before installing or wiring a module, you must verify that the external power supply is
turned off. Otherwise, you may get an electric shock, or the product may be damaged.
 After you complete installing or wiring the module, make sure that a terminal block cover is
installed on the module before turning on the power supply or operating the module. If the
terminal block cover is not installed properly, you may get an electric shock, or the module
may not operate normally.
 Be sure the protective ground connection (PE) and functional ground (FE) FE are
with protective grounding conductors. Otherwise, you may get an electric shock, or the
module may not operate normally.
 To ensure that a PLC is wired correctly, you must check the rated voltage of the product
and the arrangement of the terminals. If the PLC is connected to a power supply that does
not conform to the rated voltage, or the product is not wired correctly, a fire may occur, or
the product may be damaged.
 The external connections should be crimped, press-welded by specific tools, or soldered
correctly. Improper connections may result in a short circuit, fire, or malfunction.
 Tighten the terminal screws to the specified torque. If the terminal screws are loose, a
short circuit, fire, or faulty operation may occur. Tightening the terminal screws too far may
cause damage to the terminal screws or the module, resulting in a short circuit or
malfunction.
 Make sure there are no foreign substances such as iron filings or wiring debris inside the
module. Foreign substances may result in a fire, damage, or malfunction.
 Things to note while wiring an I/O module
(1) Terminal definitions
◆ Two-/three-wire (passive sensor): the sensor and the system share the same power circuit.
◆ Four-wire (active sensor): the sensor uses an independent power supply and should not share the
same power circuit with the system.
(2) Terminals with insulation sleeves cannot be used as a terminal block. It is recommended that the
terminals be covered with insulation tubes.
(3) For wiring, use single-wire cables or two-wire cables with a diameter of 24 AWG to 16 AWG and use
it with a less than 2 mm needle type terminal (with the insulated coating crimp sleeve). Only use
copper conducting wires with a temperature rating of 60/75°C. The tightening torque of the PLC
terminal screw is 2.0 kgf-cm (1.77 lbf-in).
