  • Page 2: For Safe Use

    For Safe Use ◆ Introduction This product generates high voltage and energy. In order to use the product safely and prior to using the product, please read the instruction manual to the end before use in order to use the product safely, because there is a danger of death or serious injury due to electric shock.
  • Page 3 WARNING ◆ Understand the risk. Products generate high voltage and energy. An electrician or equivalent knowledge must read the instruction manual to the end and familiarize yourself with the proper use and danger of the product. If you want the product to be handled by another person, limit it to those with knowledge of electricity, and have people who are familiar with correct use and danger of the product conduct education and training before handling it, or handle the product under the supervision of those who are familiar with the proper use and danger of the product.
  • Page 4 WARNING ◆ Designed for indoor use Use the product indoors. Do not use it outdoors or indoors where there is a possibility of water leakage, flooding, or crown. ◆ About operating temperature and humidity Use within the range of operating temperature and humidity stated in the instruction manual. Do not use it in a place where the ambient temperature becomes higher than the operation temperature of the product or in a narrow closed place.
  • Page 5 CAUTION ◆ Install horizontally. Do not install the product in the reverse direction and the lateral direction. Internal heat dissipation becomes insufficient, parts deteriorate, there is a risk of smoke and fire. ◆ Do not install in the place where cool air blows directly. There is a danger of condensation, leakage current and burnout.
