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.

NOTE

•  Take note that traces of sheet metal processing be left in our power supplies.
•  When disposing product, follow disposal laws of each municipality.
•  When exporting our products, apply for necessary permissions as required by rules and regulations of Foreign Exchange 

and Foreign Trade Control Act.

•  Catalogue,  contents of the instruction manual may be changed without a prior notice. Refer to latest catalogue or 

instruction manual.

•  Reproduction or reprinting the instruction manual or its portion is forbidden without our permission.
