[Installation Precautions]
• Use the programmable controller system in the operating environment that meets the general
specifications of this manual.
Using in any other environment may cause electric shocks, fires, malfunctions, or damage or
deterioration of the product.
• While pressing the installation lever located at the bottom of module, insert the module fixing tab
into the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing
hole as a supporting point.
Incorrect installation may cause malfunctions, fault or drop of the module.
When using the module in an environment where constant vibrations may occur, secure it with
screws. Tighten the screws within the specified torque range.
Loose tightening may cause a drop of the module, a short circuit or malfunctions.
Excessive tightening may cause the same as the above due to damage to the screws or the
module.
• Be sure to shut off all phases of the external power supply used by the system before mounting
or dismounting the module.
Failure to do so may damage the product.
• Do not directly touch the conducting parts and electronic parts of the module.
Doing so may cause a malfunction or a fault of the module.
[Wiring Precautions]
• Carefully prevent foreign matter such as chaff and wire chips from entering the inside of the
module.
They may cause a fire, fault or malfunction.
• The module has an ingress prevention label on its top to prevent foreign matter, such as wire
offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat dissipation.
• For the CC-Link/LT, use the cables specified by the CC-Link Partner Association.
The performance of the CC-Link/LT cannot be assured if any other cables than the specified are
used.
Also, observe the network wiring specifications given in Chapter 3.
Normal data communication is not guaranteed if the wiring is not conducted according to the
specifications.
• Place the communication cables or power cables for the module in a duct or to fasten them with
clamps.
If not, the dangling condition, shift or inadvertent pulling of the cables may lead to damage to the
module or cables, or a malfunction due to faulty cable connection.
