Note 1:
The life of a capacitor is affected by the ambient temperature. See page 6–21.
Note 2:
Designed life of a cooling fan is.10 years. However, it is affected by the ambient
temperature and other environmental conditions.
Note 3:
The inverter must be cleaned periodically. If dust accumulates on the fan and
heat sink, it can cause overheating of the inverter.
