    Use the product with the rated voltage described in the specification. If the voltage exceeds the maximum rating, overheating or fire
    may occur.

                                                                      Caution
    Do not store the product in the area where temperature exceeds the maximum rating, where there is too much moisture or damp-
    ness, where there is acid gas or corrosive gas, or other extreme conditions. Otherwise, failure, overheating or fire may occur.
