[INSTALLATION PRECAUTIONS] 
!
 CAUTION 
 Use the PLC in an environment that meets the general specifications contained in this manual. 
Using this PLC in an environment outside the range of the general specifications could result in 
electric shock, fire, erroneous operation, and damage to or deterioration of the product. 
 
 Hold down the module loading lever at the module bottom, and securely insert the module 
fixing latch into the fixing hole in the base unit. 
Incorrect loading of the module can cause a malfunction, failure or drop. 
When using the PLC in the environment of much vibration, tighten the module with a screw. 
Tighten the screw in the specified torque range. Undertightening can cause a drop, short circuit 
or malfunction. Overtightening can cause a drop, short circuit or malfunction due to damage to 
the screw or module. 
 
 When installing extension cables, be sure that the connectors of base unit are installed 
correctly. After installation, check them for looseness. Poor connections could cause an input or 
output failure. 
 
 Securely load the memory card into the memory card loading connector. After loading, check 
for lifting. Lifting can cause a malfunction due to a contact fault. 
 
 Completely turn off the external power supply before loading or unloading the module. Not 
doing so could result in electric shock or damage to the product. 
 
 Do not directly touch the module's conductive parts or electronic components. Touching the 
conductive parts could cause an operation failure or give damage to the module. 
 
[WIRING PRECAUTIONS] 
!
 DANGER 
 Completely turn off the external power supply when installing or placing wiring. Not completely 
turning off all power could result in electric shock or damage to the product. 
 
 When turning on the power supply or operating the module after installation or wiring work, be 
sure that the module's terminal covers are correctly attached. Not attaching the terminal cover 
could result in electric shock.
