(2) Supply all power to the power supply terminals from the same source.

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.
Note
(1) Never apply a voltage that exceeds the input voltage for Input Units or the
maximum switching capacity for Output Units.
(2) When the power supply has positive and negative terminals, always wire
them correctly.
(3) When required by EC Low Voltage Directive, use reinforced insulation or
double insulation on the DC power supply connected to DC-power-supply
CPU Units and I/O.
For the DC power supply connected to a DC-power-supply CPU Unit, use
a power supply with a minimum output holding time of 10 ms.
(4) Do not pull on the cables or bend the cables beyond their natural limit. Do-
ing either of these may break the cables.
