ABB Frequency Converter ACS 601-0100-5

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

Choose the cleaning method used

If using compressed air, ensure the cleaning is carried out in another room or outdoors.

Was fan rotation prevented during cleaning?

Sign off on the heatsink cleaning

Warning: Only trained personnel should perform this procedure

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

Enter the current hours of the cooling fan

Is there increasing noise from fan bearings?

Is there a gradual rise in the heatsink temperature?

If any of the above symptoms are present, proceed with fan replacement

Fan can be withdrawn by removing the bottom of the frame

Was the fan successfully removed?

Upload a photo of the removed fan

Warning: This procedure requires trained personnel only!

Enter the current hours of the capacitors

Is the ambient temperature lowered?

Check if there is a mains fuse failure or a Fault trip

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

Upload a photo of the suspected faulty capacitor

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