CAUTION ON USE
• Product individual notes are shown in the instruction manual. If there is any difference with common notes individual
notes shall have priority.
• Before using this product, be sure to read the catalog and instruction manual. There is risk of electric shock or damage
to the product or fire due to improper use.
• Input voltage, Output current, Output power, ambient temperature and ambient humidity should be kept within
specifications, otherwise the product will be damaged, or cause electric shock or fire.
• Insert fuse at the input to prevent smoke, fire during abnormal operation.
• For externally mounted fuse do not use other fuses aside from our specified and recommended fuse.
• This product was made for general purpose electronic equipment use and is not designed for applications requiring
high safety (such as extremely high reliability and safety requirements. Even though high reliability and safety are not
required, this product should not be used directly for applications that have serious risk for life and physical safety.
Take sufficient consideration in failsafe design (such as providing protective circuit or protective device inside the
system, providing redundant circuit to ensure no instability when single device failure occurs).
• When used in environments with strong electromagnetic field, there is possibility of product damage due to malfunction.
• When used in environment with corrosive gas (hydrogen sulfide, sulfur dioxide, etc.) , there is possibility that they might
penetrate the product and lead to failure.
• When used in environments where there is conductive foreign matter or dust, there is possibility of product failure or
malfunction.
• Provide countermeasure for prevention of lightning surge voltage as there is risk of damage due to abnormal voltage.
• Take care not to apply external abnormal voltage to the output. Especially, applying reverse voltage or overvoltage more
than the rated voltage to the output might cause failure, electric shock or fire.
