INSTRUCTION MANUAL

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.

• If the builtin fuse is blown, do not use the product even after replacing the fuse as there is risk of abnormality

inside. Be sure to request repair to our company.

• For products without builtin protection circuit (element, fuse, etc.), insert fuse at the input to prevent smoke,

fire during abnormal operation.
As for products with builtin protection circuit, depending on usage conditions, builtin protection circuit might
not work. It is recommended to provide separate proper protection circuit.

• 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 failsafe 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.

• Connect together the frame ground terminal of the product and the ground terminal of the equipment for safety
and noise reduction. If these grounds are not connected together, there is risk of electric shock.

• Parts with lifetime specifications (builtin electrolytic capacitor) are required to be replaced periodically.
Set the overhaul period depending on the environment of usage and perform maintenance.
Also, note that there are cases when EOL products cannot be overhauled.

• 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.

• This product has possibility that hazardous voltage might occur in output terminal depending on failure mode.
The output of these products must be protected in the end use equipment to maintain SELV.

• The output of these product is considered to be a hazardous energy level (The voltage is 2V or more and the power
is 240VA or more). It must not be made accessible to users.

• Protection must be provided for Service Engineers against indirect contact with the output terminals and/or to
prevent tools being dropped across them.

• While working on this product, the AC input power must be switched off and the input and output voltage
should be zero.
