Fan Replacement
Contact with hazardous voltage could result in death or serious injury.

Do not attempt to replace fans until power has been removed and 5 minutes have passed to allow
internal voltage to discharge.
In the event that the cooling fans fail and results in a frequent occurrence of Fault 7: Overheated Drive faults,
the fans are replaceable. Refer to
Replacement kits.
