Inspection and
maintenance of
consumable parts
When conducting inspection or maintenance, treat the cooling fan and electrolytic
capacitor as consumable parts as they have a given electrical and mechanical life
respectively.
For example, when they are used under the rated specifications, the life of the cooling
fan is about 10,000 hours, and that of the electrolytic capacitor is about 8,000 hours.
Their actual duration depends on how those items are used by customers.
