[DESIGN PRECAUTIONS]
Do not write data into the "system area" of the buffer memory of intelligent
function modules. Also, do not use any "prohibited to use" signals as an
output signal to an intelligent function module from the programmable
controller CPU.
Writing data into the "system area" or outputting a signal for "prohibited to
use" may cause a programmable controller system malfunction.
Do not bunch the control wires or communication cables with the main circuit
or power wires, or install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
[INSTALLATION PRECAUTIONS]
Use the programmable controller in the environment conditions given in the
general specifications in the User's Manual for the CPU module. Failure to do
so may cause an electric shock, fire, malfunction, or damage to or
deterioration of the product.
While pressing the installation lever located at the bottom of the module,
insert the module fixing projection into the fixing hole in the base unit, and
mount the module with using the hole as a supporting point. Incorrect module
mounting may cause a malfunction, failure, or drop of the module. After
mounting the module to the base unit securely hold the module with module
fixing bracket.
The screws must be tightened within the specified torque range. If the screw
is too loose, it may cause a drop or malfunction. Excessive tightening may
damage the screw and/or the module, resulting in a drop or malfunction.
Be sure to shut off all phases of the external power supply used by the
system before mounting or removing the module. Failure to do so may cause
damage to the product.
Do not directly touch any conductive part or electronic part of the module.
Doing so may cause a malfunction or failure of the module.
