electrocution.
➢
Do not apply heavy force on the cables or drag or clip the cable too hard to prevent cable from damage
or terminal from loosening while avoiding electrocution.
➢
Confirm that the input voltage is within the rating scope.
➢
Do not attempt to disassemble or modify the module or repair the module privately; otherwise, it may
lead to product failure, fire or personnel injury.
After replacing the CPU module, confirm that all programs and parameters are being created in the
➢
new CPU module and are duly set. Following that, you may start the PLC System to prevent the
controlled component from executing a false action.
Please read the manuals carefully in order to get familiar with the required operation mechanisms
➢
when the PLC is running such as procedure change, forced output and RUN/STOP, etc. The purpose is
to prevent incorrect output or equipment damage as may be caused by inaccurate operations.
Before touching the module, please touch the grounding metal first or wear an anti-static bracelet in
➢
order to discharge the electrostatic from the human body to prevent it from damaging the module.
When using a mobile phone or communication device, please keep appropriate distance to prevent
➢
from interfering with the system as to cause the false action.
Do not install the PLC Control System in an environment exposed to direct sunlight or humidity.
➢
Please confirm that appropriate distance has been maintained between the PLC Control System and
➢
the heat source such as coil, heater and resistor, etc. to prevent the component from being exposed
to higher temperature.
Please install an emergency power shutdown system and an over-current protection device as
➢
required in order to protect the PLC Control System.
During the operations and maintenance process, please check the installation stability in order to
➢
avoid unexpected vibrations as to damage the PLC Control System and the controlled component.
