ABB Frequency Converter ACP 601-0070-5

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), use compressed air.

Compressed air used for cleaning?

Prevent fan rotation when using compressed air for heatsink cleaning to prevent bearing wear.

Fan rotation prevented during cleaning?
