Wiring Built-in I/O
Wiring Precautions
Double-checking I/O
Specifications
Double-check the specifications for the I/O Units. In particular, do not apply a
voltage that exceeds the input voltage for Input Units or the maximum switch-
ing capacity for Output Units. Doing so may result in breakdown, damage, or
fire.
When the power supply has positive and negative terminals, always wire them
correctly.
Electric Wires
• AWG22 to AWG18 (0.32 to 0.82 mm
2
) power lines are recommended.
Use cable with a maximum diameter of 1.61 mm including the insulation
covering.
• The current capacity of electric wire depends on factors such as the ambi-
ent temperature and insulation thickness, as well as the gauge of the con-
ductor.
• M3 self-rising screws are used for all screw terminals including terminal
screws for crimp terminal power supply wiring.
• Use crimp terminals or solid wire for wiring.
• Do not connect bare stranded wires directly to terminals.
• Tighten the terminal block screws to the torque of 0.5 N·m.
• Use crimp terminals (M3) having the dimensions shown below.
Wiring
• Wire the Units so that they can be easily replaced.
• Make sure that the I/O indicators are not covered by the wiring.
• Do not place the I/O wiring in the same conduits or ducts as high-voltage
or power lines. Inductive noise can cause errors or damage.
• Tighten the terminal screws to the torque of 0.5 N·m.
