5.1.1 Precautions for Handling

CAUTION
Use C80 in an environment that meets the general specifications contained in this manual.
Using C80 in an environment outside the range of the general specifications could result in electric shock, fire,
operation failure, and damage to or deterioration of the product.
When mounting the module, be sure to insert the module fixing hook on the module's bottom into the module
fixing hole on the base unit. Incorrect mounting could cause an operation failure or a damage/drop of the unit.
Hold down the module loading lever at the module bottom and securely insert the fixing hook into the fixing
hole in the base unit. Install the module with the module fixing hole as a supporting point. Incorrect mounting
could cause an operation failure or a damage/drop of the unit.
Be sure to fix all the modules with screws to prevent them from dropping.
The fixing screws (M3 x 12) are to be prepared by user.
Tighten the screw in the specified torque range. Under tightening may cause a drop, short circuit or operation
failure. Over tightening may cause a drop, short circuit or operation failure due to damage to the screw or
module.
Be sure to install the extension cable to connectors of the basic base unit correctly. After installation, check
them for looseness. Poor connections could cause an input or output failure.
Completely turn off all lines of external power supply used in the system before loading or unloading the
module. Not doing so could result in electric shock or damage to the product.
Do not mount/dismount the modules or base over 50 times. Mounting/dismounting over 50 times may cause
an operation failure.
Do not directly touch the module's conductive parts or electronic parts. Touching these parts could cause an
operation failure or give damage to the module.
Do not touch the radiating fin of the CNC CPU module while an electric current is supplied or in a short while
after the power OFF. Touching the fin may cause burns. Take care when removing the unit.
When removing the unit, always remove the fixing screws and then take the fixing hook out from the fixing
hole. Incorrect removal will damage the module fixing hook.
