5.1 Module Installation
5.1.1 Instructions for Handling
(1) Use C70 in an environment that meets the general specifications contained in this manual. Using C70 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.
(2) While pressing the installation lever located at the bottom of module, insert the module fixing projection
into the fixing hole in the base unit until it stops. Then, securely install the module with the fixing hole as
a supporting point. Incorrect installation of the module can cause an operation failure, damage or drop.
(3) While pressing the installation lever located at the bottom of module, insert the module fixing projection
into the fixing hole in the base unit until it stops. Then, securely install the module with the fixing hole as
a supporting point. Incorrect installation of the module can cause an operation failure, damage or drop.
(4) All screws for the module must be tightened to avoid drop.
Module fixation screws (M3 x 12) must be prepared by the user. Use provided module fixation screws
(M3 x 13) for CNC CPU module.
(5) Tighten the screw in the specified torque range. Loose screw 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.
(6) Be sure to connect the extension cable to connectors of the basic base unit correctly. After connecting,
check them for looseness. Poor connections could cause an input or output failure.
(7) Completely turn off the externally supplied power used in the system before installation or removing the
module. Not doing so could result in electric shock or damage to the product.
(8) Do not install/remove the module onto/from base unit or terminal block more than 50 times, after the first
use of the product. Failure to do so may cause the module to malfunction due to poor contact of
connector.
(9) Do not directly touch the module's conductive parts and electronic components. Doing so may cause an
operation failure or give damage to the module.
(10) Do not touch the heat radiating fins of controller or servo amplifier's, regenerative resistor and
servomotor, etc. while the power is ON and for a short time after the power is turned OFF. In this timing,
these parts become very hot and may lead to burns. Remove the modules while paying attention.
(11) Always remove the module by removing the module fixing screw and then taking the module fixing
projection off the module fixing hole of the base unit. Attempting to remove the module by force may
damage the module fixing projection.
