ABB ABB Frequency Converter ACS 601-0060-3 ACS 601-0060-3

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

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

Fan rotation prevented during cleaning

Sign off on the heatsink cleaning

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 checks indicate fan failure, proceed with the replacement

Fan can be withdrawn by removing the bottom of the frame

Upload a photo of the removed fan

Replacement fans are available from ABB. Do not attempt operation with other than ABB specified spare parts

Warning: This procedure requires trained personnel with PPE!

Enter the current hours of the ACx 600 intermediate circuit

Is the frequency converter loading normal?

Is the ambient temperature within the acceptable range?

If the ambient temperature is high, take measures to lower it.

Is there a mains fuse failure or a Fault trip?

If yes, contact ABB for capacitor failure suspicion.

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).
