[Wiring Precautions]
WARNING
●
Make sure to cut off all phases of a power supply externally before attempting installation or wiring
work. Failure to do so may cause electric shock or damage to the product.
●
Make sure to attach the terminal cover, provided as an accessory, before turning on the power or
initiating operation after installation or wiring work. Failure to do so may cause electric shock.
●
The temperature rating of the cable should be 80
or more.
●
Make sure to properly wire to the spring clamp terminal block in accordance with the following
precautions. Failure to do so may cause electric shock, equipment failures, a short-circuit, wire
breakage, malfunctions, or damage to the product.
(1) The termination size of the cable end should follow the dimensions described in the manual.
(2) Twist the ends of stranded wires and make sure that there are no loose wires.
(3) Do not solder-plate the electric wire ends.
(4) Do not connect more than the specified number of wires or electric wires of unspecified size.
(5) Affix the electric wires so that neither the terminal block nor the connected parts are directly
stressed.
CAUTION
●
Perform class D grounding (grounding resistance: 100
Ω
or less) of the grounding terminal on the
CPU module and extension modules with a wire 2 mm
2
or thicker.
●
Connect power supply wiring to the dedicated terminals described in this manual. If an AC power
supply is connected to a DC input/output terminal or DC power supply terminal, the programmable
controller will burn out.
●
Do not wire vacant terminals externally. Doing so may damage the product.
●
Install modules so that excessive force will not be applied to terminal blocks, power connectors, I/O
connectors, communication connectors, or communication cables. Failure to do so may result in wire
damage/breakage or programmable controller failure.
●
If abnormal data is written to a programmable controller due to the effect of noise, malfunction of the
programmable controller may occur which may damage machines or cause accidents. To prevent
this, observe the following precautions:
(1) Do not bundle a power line, control line, and communication cables together with or lay them
close to the main circuit, a high-voltage line, load line, or power line. As a guideline, lay the power
line, control line, and connection cables at least 100 mm away from the main circuit, high-voltage
line, load line or power line.
(2) Ground the shield of an analog input/output cable at one point on the signal receiving side.
However, do not use common grounding with heavy electrical systems.
●
Check the interface type and correctly connect a cable. Incorrect wiring or connecting a cable to an
incorrect interface may cause failure of the module and external device.
