Note 1. "Ambient temperature" refers to the temperature measured at a distance of approximately 5 cm from the
bottom center of the inverter (atmospheric temperature).
It refers to an interior temperature if the inverter is stored in a cabinet.
2. The smoothing capacitor has a limited life because it is subjected to chemical reaction inside the part
and, as a guide, needs to be replaced once a decade approximately. (This period is an expected design
life, and not the guaranteed value.)
However, if the inverter is used at a high ambient temperature or in a heavy loaded environment, such
as at the over-rated current, its life will be significantly shortened.
