Warning: Only trained personnel should perform this procedure

Enter the current usage hours of the ACx 601 unit

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 symptoms are present, fan replacement is recommended

Upload a photo of the fan before removal

Remove the bottom of the frame to withdraw the fan

Upload a photo of the fan after removal

Warning: This procedure requires trained personnel with PPE!

Is the ambient temperature lowered?

If capacitor failure is suspected, contact ABB immediately.

Check if mains fuse failure or a Fault trip has occurred

Enter the ABB specified spare part number for replacement

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

Sign off on the capacitor replacement

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.
