Inappropriate use may result in electric shock, injury or fire. Warning ● This product is subject to high voltage. Do not touch it while the power is on. Failing to do so may result in electric shock. Caution ● This product is designed for the lighting of a Cold Cathode Fluorescent Lamp. Do not use it with any other load. ● Store this product under the conditions defined in the specification document. ● Do not store this product in an environment where dust, dirt or corrosive gas(salt,acid,base, etc.) is present. ● This product is subject to high voltage. If there is a possibility that the user may touch the product, provide a proper indication in order to draw the user's attention. ● This product is designed for use with general electronic equipment. If it is to be used with medical equipment that directly affects human life or for the control of transportation equipment to which passengers entrust their lives, provide thorough fail-safe measures. ● Avoid using this product under high temperatures or high humidity or in an environment in which dust, dirt or any corrosive gas (salt,acid,base, etc.) is present. Also,be careful not to allow the formation of dew condensation. It may result in damage or electric shock. ● If the product does not have a built-in protective circuit (circuit breaker, fuse, etc.), it is recommended that a fuse be used at the input stage to prevent the generation of smoke or fire in the event of a malfunction. Even when the product has a built-in protective circuit (circuit breaker, fuse, etc.), the circuit may not function properly due to inappropriate operating conditions or power-supply capacity. It is recommended that an appropriate protective circuit (circuit breaker, fuse, etc.) be provided separately from the built-in circuit. ● Use the product only within the specified input voltage, output power, output voltage and operating temperature ranges. Exceeding these values may result in damage, etc. ● Provide a measure for the prevention of surge voltage due to lightning, etc. Abnormal voltage may result in damage, etc. ● To prevent problems arising from short-circuiting of the high-voltage section, provide appropriate measures to prevent the entry of foreign substances following installation. ● This product is not designed to provide resistance to radiation. ● Ripples could be superimposed on the voltage and the current in the input source connected to the inverter , depending on the impedance in the input source, wiring, etc. When you select an input source, please check waveforms, etc on the final set. Handling Precautions ● This product uses thin wires. Observe the following precautions and handle it with care so as not to cause wire breakage. Broken wire may result in damage, etc. ・Do not stack multiple products on top of one another. ・Do not allow the product to come in contact with tools, etc. ● Do not apply excessive stress during installation. It may cause chipping and cracking,resulting in damage, etc. ● Provide clearance between the high-voltage section of this product and the frame body on which the product is installed and also the conductor section as per listed on page 2 , [1] ”Outline” . ● Please do not use the product, when dropping it, since there is a possibility of the parts damage. Please confirm abnormality is not found in the product enough when using it by any chance.
