• While this product is operating, keep your hands and face away from it as you may be injured by an
unexpected situation.

• There are cases where high voltage charge remains inside the product. Therefore, do not touch even if they are
not in oepration as you might get injured due to high votlage and high temperature.
You might also get electric shock or burn.

• Do not make unauthorized changes to this product nor remove the cover as you might get an electric shock or
might damage the product. We will not be held responsible after the product has been modified, changed or
disassembled.

• Do not use this product under unusual condition such as emission of smoke or abnormal smell and sound etc.
Please stop using it immediately and shut off the product.
It might lead to fire and electric shock. In such cases, please contact us. Do not attempt repair by yourself, as it
is dangerous for the user.

• Do not operate and store these products in environments where condensation occurs due to moisture and
humidity. It might lead fire and electric shock.

• Do not drop or apply shock to this product. It might cause failure. Do not operate these products mechanical
stress is applied.

CAUTION on MOUNTING

• Confirm connections to input/output terminals are correct as indicated in the instruction manual before
switching on.

• Input/output line, please use the wires as short and thick as possible.

• Do not use this product in special environment with strong electromagnetic field, corrosive gas or conductive
substances and direct sunlight, or places where product is exposed to water or rain.

INSTRUCTION MANUAL

CAUTION on USE

• Product individual notes are shown in the instruction manual. If there is any differnce 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.

• 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 possiblity 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 ground is not connected together, there is risk of electric shock.

• Parts with lifetime specifications (builtin fan, 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 have a builtin fan for aircooling. Do not block the air intake and exhaust as this might lead to
fire.

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

Note

• Consider storage of the product at normal temperature and humidity avoiding direct exposure to sunlight at

environment with minimal temperature and humidity changes. Storage of product at high temperature, high
humidity and environments with severe changes in temperature and humidity might cause deterioration, and
occurrence of condensation in the product.

• When disposing product, follow disposal laws of each municipality.

• Published EMI (CE, RE) or immunity is the result when measured in our standard measurement conditions and

might not satisfy specification when mounted and wired inside enduser equipment.
Use the product after sufficiently evaluating at actual enduser equipment.

• CE Marking

CE Marking, when applied to a product covered by this handbook, indicates compliance with the low voltage
directive.

3. Connecting method

Pay attention to the input wiring. If it is connected to wrong terminal, the power supply will be damaged.

• Input must be off when making connections.

• Connect terminal to earth (frame ground of the equipment etc.) by thick wire for safety and improvement

of Noise sensitivity.

Standard

• Basic connection (Local sensing)
Connect "+S" terminal (Pin No.2) to "+Vm" terminal (Pin No.1), and "S" terminal (Pin No.10) to "Vm"
terminal (Pin No.9) with the attached short pieces. (Short pieces are mounted at time of shipment.)
