### The manufacturer shall furnish fan replacement instructions and the expected fan service life at the ambient temperature indicated in the datasheet.
### Cooling fans are the shortest-lived component in the drive and the most common cause of an overtemperature shutdown after a fouled intake. Both failures are correctable the same day when the replacement is already on site. {note}
