*1. The capacitor service life is influenced by the ambient temperature.
For the replacement guideline, refer to A-2 Smoothing Capacitor Life Curve on page A-8.
*2. The life of the cooling fan depends on environmental conditions, such as the ambient temperature and/or dust.
Check the operating conditions in daily inspection.
*3. The replacement interval (in years or cycles) and the smoothing capacitor life curve are based on the expected
design life and not guaranteed data.
