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.
 For products with no cover, do not touch them as there are high-voltage and high temperature parts inside. Touching them might
cause injury such as electric shock or burn.
 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, when 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.
 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.
