ABB Enclosed Variable Speed/Frequency Drive ACS880-07-0650A-3

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 if some of the components have already been renewed earlier

If some components have been renewed earlier, their mission time is restarted. However, the remaining mission time of the whole circuit is determined by its oldest component.

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.

Warning: Do not remove or insert the memory unit when the control unit is powered.

Drive stopped and electrical safety precautions followed

Upload a photo of the memory unit before removal

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! Do not use the module extraction/installation ramp with plinth heights that exceed the maximum allowed height.

Attach the module extraction/installation ramp carefully.

Make sure that the module does not fall over when you move it on the floor.

Do not roll the module on its wheels for a longer distance than what is required for inserting or extracting the module.

To prevent the drive module from falling, attach its top lifting lugs with chains to the cabinet before you push the module into the cabinet and pull it from the cabinet.

Push the module into the cabinet and pull it from the cabinet carefully preferably with help from another person.

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

Unplug quick connector(s) at the right top corner of the control unit mounting plate.

Remove the control unit mounting plate.
