Mount this product properly in accordance with the instruction manual, mounting direction and shall be properly ventilated.
Please turn off the input power when doing wiring to connect to the input/output of the product.
When installing in environment where conductive foreign, dust and liquid may be present, please consider penetration and take actions to prevent the above
foreign material from entering the buffer module by installing filter. In order to prevent trouble or malfunction.
CAUTION ON USE
Product individual notes are shown in the instruction manual. If there is any difference with common notes, individual notes shall have priority.
Before using this product, be sure to read the catalog and instruction manual. There is risk of electric shock or damage to the product or fire due to improper
use.
Input voltage, Buffer current, Buffer power, ambient temperature and ambient humidity should be kept within specifications, otherwise the product will be
damaged, or cause electric shock or fire.
If the built-in fuse is blown, do not use the product even after replacing the fuse, as there is risk of abnormality inside. Kindly request repair to our company.
This product with built-in protection circuit, depending on usage conditions, built-in protection circuit may not work. It is recommended to provide a separate
protection circuit (element, fuse, etc.), insert fuse at the input to prevent smoke, fire during abnormal operation.
This product is made for general purpose electronic equipment use and is not designed for applications requiring high safety (such as extremely high reliability
and safety requirements. Even though high reliability and safety are not required, this product should not be used directly for applications that have serious risk
for life and physical safety). Take sufficient consideration in fail-safe design (such as providing protective circuit or protective device inside the system).
When used in environments with strong electromagnetic field, there is possibility of product malfunction.
