WARNING
●
To prevent an accident or equipment damage, you must configure an emergency stop circuit external to
this product.
●
Overcurrent or overvoltage might damage components, resulting in an accident, fire, or damage to
equipment. Do not exceed the rated maximum input or output current or input voltage values of the
PI/O modules.
●
Removing or installing modules with the power supply module turned on might cause electric shock or
accident. Turn off the power supply module before performing these tasks.
●
Check the wiring carefully before turning on the system. Improper wiring can result in electric shock or
fire.
●
Incorrect use of the system can lead to accidents and equipment damage. Check the safety of peripheral
equipment before modifying a running program or performing RUN or STOP operations.
CAUTION
●
Do not insert a finger or foreign object into the gap between a connector and the mount base. Doing so
might lead to injury or cause the system to malfunction.
●
To avoid fire, use an external power supply with an overvoltage and overcurrent protection function.
●
To avoid fire, if you see smoke or smell an unusual odor, turn off the power immediately and
investigate the source.
●
Do not obstruct the ventilation slots at the top and bottom of the modules. Doing so might cause smoke
or fire, or lead to module failure or malfunction.
●
The modules have open ventilation slots at the top and bottom. To avoid smoke, fire, and module failure
or malfunction, take the necessary measures to prevent objects from falling into the slots.
Notice
●
The cabinet in which the CPU and PI/O modules of the S10VE are mounted must have ventilation holes
in the door and top panel, or have a fan installed in the door. To improve airflow within the cabinet,
make sure that there are gaps at the top, bottom, and sides of each mount base. Failing to provide these
gaps might lead to module failure or malfunction.
●
To avoid failure and malfunction, consider the following measures during installation design to ensure
that the intake air temperature at the center of the base of the power supply module and CPU modules
does not exceed 55°C:
- Make sure there is plenty of space between a unit and those above and below it
-
Use a fan to perform forced air cooling
-
Install a waste heat duct
-
Install a cooler for the control panel
●
To prevent equipment damage during transport, protect the equipment with cushioning material and
transport it as you would a precision instrument.
