*1. The life of the smoothing capacitor depends on ambient temperatures.
Refer to "Appendix-2 Product Life Curve" for the replacement reference.
*2. The life of the cooling fan varies depending on the environmental conditions, such as ambient temperature
and/or dust. Check the operation through daily inspections.
*3. The replacement reference (year/cycle) or "
Appendix-2 Product Life Curve
" is based on the expected design
life, which is not guaranteed.
