4 PROCEDURES AND SETTINGS BEFORE OPERATION

4.5 Wiring

4.5.1 Precautions for handling the CC-Link dedicated cables

4.5.2 Connection of the CC-Link dedicated cables

CAUTION
Avoid the following extreme handling. Such handling will damage the CC-Link
dedicated cables.
• Compress the cable with a sharp edge.
• Twist the cable extremely.
• Pull the cable extremely hard. (More than permissible tension)
• Step on the cable.
• Put an object on the cable.
• Scratch the cable sheath.
• Before starting installation or wiring work, be sure to shut off all phases of external
power supply used by the system. Failure to shut off all phases could lead to electric
shocks, product damage or malfunctioning.
• Always install the terminal covers enclosed with the product before turning ON the
power or operating the product after installation or wiring work.
Failure to install the terminal cover could lead to electric shocks.
• Before cleaning or tightening the terminal screws, be sure to shut off all phases of
external power supply used by the system. Failure to shut off all phases could lead
to module trouble or malfunctioning. A loose screw could lead to dropping, short-
circuiting or malfunctioning. If the screw is too tight, dropping or short-circuiting
malfunctioning could occur due to screw damage.
• Do not bind the control wire or communication cable with the main circuit or power
wire, or place the control wire near these. Separate by at least 100mm or more.
Failure to observe this could lead to malfunctions caused by noise.
• Always ground the FG terminal with Class D grounding (grounding resistance :
100 or less) or higher dedicated of the programmable controller.
Ω
Failure to do so could lead to electric shock or malfunctioning.
• Always confirm the product's rated voltage and terminal layout before wiring the
module. Connecting with a power supply other than the rated power supply, or
incorrect wiring could lead to fires or trouble.
• Securely mount the connector of each connection cable to the mounting section.
An incomplete connection could lead to malfunctioning causes.
• Be sure to fix the wires or cables by ducts or clamps when connecting them to the
module. Failure to do so may cause damage of the module or the cables due to
accidental pull or unintentional shifting of the cables, or malfunctions due to poor
contact of the cable.
• Do not install the control lines together with the communication cables, or bring them
close to each other. Failure to do so may cause malfunctions due to noise.
• Always connect the master module and CC-Link dedicated cable at the data link
terminal block. If the data link terminal block and general-purpose output terminal
block are incorrectly inserted, module trouble could occur.
