BEFORE USING THE POWER SUPPLY

Be sure to read this instruction manual thoroughly before using this product. Pay attention to all cautions and warnings before 
using this product. Incorrect usage could lead to an electrical shock, damage to the power supply or a fire hazard.

DANGER

Never use this product in locations where flammable gas or ignitable substances are present.

INSTALLATION WARNING

When installing, ensure that work is done in accordance with the instruction manual. When installation is improper, there is

risk of electric shock and fire.

Installation shall be done by Service personnel with necessary and appropriate technical training and experience. There is a 

risk of electric shock and fire.

Do not cover the product with cloth or paper etc. Do not place anything flammable around. This might cause damage, electric 

shock or fire.

WARNING on USE

Do not touch this product or its internal components while circuit in operation, or shortly after shutdown. You may receive a 

burn.

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 operation 

as you might get injured due to high voltage 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 disassembled.

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 terminals, output terminals and signal terminals are correct as indicated in the instruction manual 

before switching on.

Input voltage, Output current, Output power, ambient temperature and ambient humidity should be kept within specifications, 

otherwise the product will be damaged or malfunction.

Input line and 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.

Mount this product properly in accordance with the instruction manual, mounting direction and shall be properly be ventilated.
Please shut down the input when connecting input and output of the product.
When installing  in environment where conductive foreign, dust and liquid may be present, please consider penetration of 

above foreign material in the power supply by installing filter, to prevent trouble or malfunction.
