2. Installation and wiring
INSTALLATION PRECAUTIONS
•
Use the module in the environment described in the USER'S MANUAL General Specification.
Do not use the PLC in places with dust, soot, conductive dust, corrosive gas or combustible
gas, places exposed to high temperature, condensation, wind or rain or places that experience
vibration or impact.
Using the module outside the range of the general specification may result in electrical shock,
fire, malfunctions, or damage to the PLC.
•
When drilling screw holes or performing wiring, make sure that cutting and wiring debris or
other foreign matter do not enter the ventilation slits of the module.
Such matter may cause fire, failure or malfunction.
•
When the installation work is completed, remove the dust protection sheet from the ventilation
slits of the PLC.
If the sheet remains attached, it may cause fire, failure or malfunction.
•
Securely connect extension cables to their specified connectors.
Poor contact may cause malfunction.
WIRING PRECAUTIONS
•
Before beginning any installation or wiring work, make sure all phases of the power supply
have been shut off.
Failing to shut off the power supply may cause electrical shock or damage to the module.
•
Following installation or wiring work, when turning on the power supply and operating the PLC,
make sure that the terminal cover provided as an accessory has been attached to the module.
Failing to attach the cover may cause electrical shock.
•
For the CC-Link system, use dedicated cables specified by the manufacturer.
The performance of the CC-Link system cannot be guaranteed with any cable other than
dedicated ones specified by the manufacturer.
For the maximum total extension length and the cable length between stations, observe the
specifications described in USER'S MANUAL.
With wiring outside the specification range, normal data transfer cannot be guaranteed.
•
Make sure to fix communication cables and power cables connected to the module by placing
them in a duct or clamping them.
Cables not placed in a duct or left unclamped may hang or shift, allowing them to be pulled
accidentally, which may result in malfunction or damage to the module and the cables.
•
When disconnecting a communication/power cable connected to the module, do not hold the
cable area.
For a cable with a connector, hold the connector attached to the cable.
For a cable connected to a terminal block, loosen screws of the terminal block before
disconnecting the cable.
If a cable is pulled while it is connected to a module, the module may malfunction or the
module and the cable may be damaged.
WIRING PRECAUTIONS
•
Use a grounding resistor of 100Ω or less with a wire of 2 mm
terminal in the PLC main units. However, never perform common grounding with a high voltage
system.

•
Do not bundle control cables and communication cables with the main circuit and power
cables. Keep control cables and communication cables at least 100 mm away from the main
circuit and power cables.
Otherwise, electric noise may cause a malfunction.

The FX

2N
M4 (0.16 in.) screws.
In the case of direct installation, provide a space of 1 to 2 mm (0.04 to 0.08 in.) between the units.
2.2 Dedicated CC-Link Cables
Use dedicated CC-Link cables in the CC-Link system.
If any other cable is used, the performance of the CC-Link system cannot be guaranteed.
2.3 Module Wiring with Dedicated CC-Link Cables
This section describes the connection method of dedicated CC-Link cables.
•
The cables can be connected regardless of the station number.
•
Make sure to connect a terminal resistor (offered as an accessory to the module) between the
terminals DA and DB in the modules at both ends of the CC-Link system.
•
In the CC-Link system, the terminal resistor required varies depending on the cable used.
When a dedicated CC-Link cable is used: 110 Ω, 1/2 W (brown, brown and brown)
-
When a dedicated high-performance CC-Link cable is used: 130 Ω, 1/2 W (brown, orange and
-
brown)
•
The master module can be connected at either and of the system.
•
Star configuration is not allowed.
•
The figure below shows the connection method.
Important
Make sure to use only one type of cable (dedicated CC-Link cables OR dedicated CC-Link high-
performance cables).
If both types of cables are used together, normal data transmission cannot be guaranteed.
Point
The shielded dedicated CC-Link cable should go through the terminals SLD and FG in each
module, and both ends should be grounded (Class D = solid grounding).
The terminals SLD and FG are connected to each other inside the module.
