12． Precautions

To ensure user's safety, check product specifications before using the product and always observe the

following precautions when using it.

 When using the product, do not allow metal and other foreign objects to get caught between power

transmitting and receiving transformer. It may cause heating or loss of efficiency.

 When installing the product, place it so that fixing metal parts and electronic components do not

protrude in the direction of the power feeding surface (black resin plate) of the power transmitting and

receiving transformers.

 During power transmission the magnetic flux density in the range of up to 60 mm from power

transmitting and receiving transformers is 27μT or more. When installing the product, ensure that heads,

pacemakers and precision equipment can not be brought close to this range.

 The product contains circuits operating at high voltage. Touching boards during power transmission

may cause electric shock.

 Even if the power transmitting transformer is within the power feeding range, increasing gap or

displacement will cause heating of the aluminum housing. When installing the product, consider the

heat resistant temperature of the housing. *Reference temperature rise value 50°C (for Gap12mm)

 The aluminum plate of the power receiving module (BWS 50 - 28S1R5R) may become hot. When

installing the product, consider the heat resistant temperature of the housing. *Reference temperature

rise value 30°C

 When using this product to charge batteries, confirming that the charging specification of batteries is

compatible with the specification of this product before using it.

 The product is intended for use in general electronics equipment (office equipment, communication

equipment, measurement equipment). Do not use the product in medical equipment, nuclear

equipment, trains, and other areas, where human life or property may be directly affected by damaged

product. For any use other than in general electronics equipment please consult the manufacturer.

 The product is not suitable for parallel operation.

 Minor changes and component changes that do not significantly affect specifications can be made

due to improvement of product characteristics and other reasons without prior notice.

 The product may be damaged if used under nonstandard electrical or environmental conditions

including temperature, etc. The product must be always used within specifications.

 Avoid storing or using the product in places where corrosive gas or dust are generated.

 The product may be damaged by static electricity. Take measures against static electricity in the

working environment, such as using grounding straps to discharge the static charge on workers, etc.

 The product does not contain build-in overvoltage protection.

 The product does not come with a test report.
