Please be sure to request delivery specifications that provide further details on the features and specifications of the products for proper and safe use.
Please note that the contents may change without any prior notice due to reasons such as upgrading.
Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.).
Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal
design.
Fully caution, if metal piece contacted with top of coil surface then it could be danger of generated heat.
Do not use for a purpose outside of the contents regulated in the delivery specifications.
