Wire Sizes

This section describes wiring methods for the G9SP-series Controller and
CP-series Expansion I/O Units.
Use the following wires to wire the power supply and external I/O devices to
the G9SP-series Controller.
Solid wire
0.32 to 0.82 mm
0.32 to 0.5 mm
Stranded wire
0.5 to 1.3 mm
0.5 to 0.82 mm
* When wiring two wires to one terminal, use two wires of the same type and
thickness.
• M3 self-rising terminals are used on the screw terminals. Tighten the ter-
minal block screws to the torque of 0.5 N·m.
• Use crimp terminals (M3) having the dimensions shown below.
6.2 mm max.
Precautions for Safe Use
• Disconnect the G9SP-series Controller from the power supply before start-
ing wiring. Devices connected to the Controller may operate unexpectedly.
• Properly apply the specified voltage to the G9SP-series Controller power
supply and input terminals. Applying an inappropriate DC voltage or any AC
voltage may result in failure of specified functions, reduced safety functions,
damage to the product, and burning.
• Never apply a voltage that exceeds the input voltage for Input Units or the
maximum switching capacity for Output Units.
• When the power supply has positive and negative terminals, always wire
them correctly.
• Be sure to separate the communications cables and I/O cables from high-
voltage/high-current lines.
• Do not bend a cable past its natural bending radius or pull in it with exces-
sive force. Doing so will damage the cable.
• Be careful not to get your fingers caught when attaching terminal blocks to
the G9SP-series Controller.
• Incorrect wiring may lead to loss of safety functions. Wire conductors cor-
rectly and verify the operation of the G9SP-series Controller before using
the system in which the Controller is incorporated.
