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 a place with dust, soot, conductive dust, corrosive gas or combustible
gas, place exposed to high temperature, condensation, wind or rain or place with vibration or
impact.
Using the module outside the range of the general specification may result in electrical shock,
fire, malfunctions, or may damage the PLC.
• When drilling screw holes or performing wiring, make sure that cutting chips, wire chips or
other foreign matter does not enter the ventilation window 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
window of the PLC.
If the sheet remains attached, it may cause fire, failure or malfunction.
• Securely connect extension cables to 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 down from the outside.
Incomplete shutdown of the power supply phases may cause electrical shock or damage in the
module.
• Following an 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.
Non-attachment of 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
specification 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 the duct or clamping them.
Cables not placed in duct or not clamped may hang or shift, allowing them to be accidentally
pulled, 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 connector, hold the connector attached to the module.
For a cable connected to a terminal block, loosen screws of the terminal block, then disconnect
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
• Grounding resistor 100Ω or less with a wire of 2 mm
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.
2.1 Installation
Install the FX -16CCL-M on the right side of an FX
2N
another extension block. (For the FX
The FX -16CCL-M can be installed using a DIN rail (DIN 46277, width: 35 mm (1.38 in.)) or directly with
2N
M4 (0.16 in.) screws.
In the case of direct installation, provide space of 1 to 2 mm (0.04 to 0.08 in.) between units.
2.2 Dedicated CC-Link Cable
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.
