Is the ambient temperature lowered to prolong capacitor life?

If capacitor failure is suspected, contact ABB. Do not attempt operation with non-ABB specified spare parts.

Upload a photo of the suspected failed capacitor

Reform (re-age) spare part capacitors once a year according to ACS 600 Capacitor Reforming Guide (code: 64059629).

Warning: The heatsink should be checked and cleaned annually to prevent overtemperature warnings and faults.

If cleaning is carried out in the same room where the unit is normally operated, use a soft brush.

Dust removed gently with a soft brush

If the installation can be taken apart and the cleaning is carried out in another room (or outdoors), compressed air can be used.

Compressed air used for cleaning

Prevent fan rotation when using compressed air for heatsink cleaning to prevent bearing wear.

Is there increasing noise from fan bearings?

Is there a gradual rise in the heatsink temperature despite cleaning?

Is the frequency converter operated in a critical part of a process?

If the above checks indicate fan failure, proceed with the replacement

Fan can be withdrawn by removing the bottom of the frame
