[INSTALLATION PRECAUTIONS]
• Use the PLC in an environment that meets the general specifications contained in the CPU
User's manual to use.
Using this PLC in an environment outside the range of the general specifications may cause
electric shock, fire, malfunction, and damage to or deterioration of the product.
• When installing the module, securely insert the module fixing tabs into the mounting holes of the
base module while pressing the installation lever located at the bottom of the module downward.
Improper installation may result in malfunction, breakdown or dropping out of the module.
Securely fix the module with screws if it is subject to vibration during use.
• Tighten the screws within the range of specified torque.
If the screws are loose, it may cause fallout, short circuits, or malfunction.
If the screws are tightened too much, it may cause damage to the screw and /or the module,
resulting in fallout, short circuits or malfunction.
• Switch all phases of the external power supply off when mounting or removing the module.
Not doing so may cause electric shock or damage to the module.
• Do not directly touch the conductive area or electric components of the module.
Doing so may cause malfunction or failure in the module.
[WIRING PRECAUTIONS]
• Make sure to shut off all the phases of the external power supply before starting installation or
wiring. Otherwise, the personnel may be subjected to an electric shock or the product to a
damage.
• Be careful not to let foreign matters such as sawdust or wire chips get inside the module.
These may cause fires, failure or malfunction.
• The top surface of the module is covered with protective film to prevent foreign objects such as
cable offcuts from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate heat ventilation.
• Be sure to fix cables leading from the module by placing them in the duct or clamping them.
Unless the cables are placed with a duct or clamped, the module or cables could be broken by
swinging or moving of the cables or unintentional pulling to cause an operation error resulting
from a contact error.
• Do not pull cables by holding them with a hand for removing the cables that are connected to the
module. To remove a cable having a connector, hold the connector connected to the module
with a hand. To remove a cable not having a connector, loosen the screws fastening to connect
the module. The cables being pulled while they are still connected to the module could break the
module or cables, or cause an operation error resulting from a contact error.
