9 zusage cautionsx q Do not use the inverter except for the EL supply. w Please avoid to use transformers that were added excessive shocks. e Please take pick out one by one and avoid the load in bulk. r Please handle output terminals (pin) of the inverter very carefully, because it outputs a very high voltage during operation and may damage human bodies. t Please do not place electronic circuit which may have magnetic influence, because the leakage magnetic flux is generated at a circumference of inverter. y Do not operate under no-load conditions or when shorted. t may be damaged as for to specific circuit. u Please handle output terminals of the inverter very carefully when operate under no-load condition, because it outputs a very high voltage and frequency by unusual generation and may damage human bodies. Also, please confirm influence to other circuit and products. i n case of operation under short conditions, do not touch inverter/transformer becouse it has a fever by high input current. 9

No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its Electronic Conponents, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC Electronic Conponents, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: Standard, Special, and Specific. The Specific quality grade applies only to devices developed based on a customer designated quality assurance program for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafis, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is Standard unless otherwise specified in NEC's Data Sheets or Data ooks. f customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
