ABB Frequency Converter ACP 601-0070-3

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.

– The cooling fan lifespan of ACx 601 units is about 60 000 hours. The actual lifespan depends on the frequency converter usage and ambient temperature.

– Fan failure can be predicted by the increasing noise from fan bearings and the gradual rise in the heatsink temperature in spite of heatsink cleaning.; – If the frequency converter is operated in a critical part of a process, fan replacement is recommended once these symptoms start appearing. The fan can be withdrawn by removing the bottom of the frame.

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