Maintenance
Cooling fan
The life span of the cooling fan depends on the drive usage and ambient
temperature.
Fan failure can be predicted by the increasing noise from the fan bearings. If the
drive is operated in a critical part of a process, fan replacement is recommended
once these symptoms start appearing. Replacement fans are available from ABB.
Do not use other than ABB specified spare parts.
Fan replacement (R1 and R2)
Only frame sizes R1 and R2 include a fan; frame size R0 has natural cooling.
WARNING!

. Ignoring the instructions can cause physical injury or

hinged fan holder slightly upward from its front edge.
