CAUTION
The following conditions must be met before using or commissioning the
components described in this manual:
−
Changes to the automation system may only be made when the power
supply is disconnected!
−
Installation and hardware modifications only by properly trained per-
sonnel.
−
The national rules and regulations of the respective country must be satis-
fied (installation, safety, EMC ...)
If you keep the prescribed environmental conditions the CPU is maintenance-free.

Please only use original spare parts of Yaskawa.
WARNING
Incorrect or faulty spare parts can cause damage, malfunction or failure as
well as affect security.
For shipping always use the original packaging.
National rules and regulations apply to the disposal of the device!
WARNING
The CPU iC921xM-x was developed as an assembly for functional safety in
accordance with the procedure described in the relevant standards. The nec-
essary risk reduction was implemented in the design and the corresponding
warnings and requirements for the user are described in this manual. Please
note that even with these measures, there is still a small residual risk to life
and health of persons and take this into account as part of the risk evaluation
for the plant/machine in which the CPU iC921xM-x is used.
The modules make use of highly integrated components in MOS-Technology. These
components are extremely sensitive to over-voltages that can occur during electrostatic
discharges. The following symbol is attached to modules that can be destroyed by elec-
trostatic discharges.
The Symbol is located on the module, the module rack or on packing material and it
indicates the presence of electrostatic sensitive equipment. It is possible that electrostatic
sensitive equipment is destroyed by energies and voltages that are far less than the
human threshold of perception. These voltages can occur where persons do not dis-
charge themselves before handling electrostatic sensitive modules and they can damage
components thereby, causing the module to become inoperable or unusable. Modules
that have been damaged by electrostatic discharges can fail after a temperature change,
mechanical shock or changes in the electrical load. Only the consequent implementation
of protection devices and meticulous attention to the applicable rules and regulations for
handling the respective equipment can prevent failures of electrostatic sensitive modules.
