ABB Enclosed Variable Speed/Frequency Drive ACS880-07-0430A-3

Check the dustiness of the air inlet meshes

If the dust cannot be removed by vacuum cleaning from outside through the grating holes with a small nozzle, proceed as follows:

Stop the drive and do the steps in section Electrical safety precautions before you start the work

Remove the fasteners at the top of the grating

Lift the grating and pull it away from the door

Place the new filter mat in the grating the metal wire side facing the door

Reinstall the grating in reverse order

Sign off on the filter replacement

Performance quality of supply voltage

Performance DC circuit capacitors reforming, spare modules and spare capacitors

Inspect IP22 and IP42 air inlet and outlet meshes

Inspect dustiness, corrosion and temperature

ABB-SACE Air circuit breaker maintenance

Sign off on the yearly drive maintenance

WARNING! Use the required personal protective equipment. Wear protective gloves and long sleeves. Some parts have sharp edges.

WARNING! Use a vacuum cleaner with antistatic hose and nozzle, and wear a grounding wristband. Using a normal vacuum cleaner creates static discharges which can damage circuit boards.

Drive stopped and electrical safety precautions followed

Drive module removed from the cabinet

Heatsink cleaned with dry, clean and oil-free compressed air from bottom to top

Vacuum cleaner used at the air outlet to trap the dust

Sign off on the heatsink cleaning

Warning: This procedure requires trained personnel with PPE!

Check if the mission time of functional safety components is expired

If the mission time is expired, proceed with the following steps

Note: Renewal of the components in the safety function circuit is economical only with larger drives that have replaceable circuit boards and other components such as relays.

Check all the components that have been renewed

The remaining mission time of the whole circuit is determined by its oldest component.
