ABB Frequency Converter ACC 601-0100-5

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?

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Fan can be withdrawn by removing the bottom of the frame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: Only trained personnel should perform this procedure.

Enter the current hours of the capacitors

Is the frequency converter loading normal?

Is the ambient temperature within the acceptable range?

Report any suspected capacitor failure

Contact ABB if capacitor failure is suspected. Do not attempt operation with other than ABB specified spare parts.

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

Warning: This procedure requires trained personnel with PPE!

If heatsink fins have dust, proceed with the cleaning procedure

If using compressed air, ensure the cleaning is carried out in another room or outdoors and prevent fan rotation to avoid bearing wear
