ABB Enclosed Variable Speed/Frequency Drive ACS880-07-0880A-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 the renewed components are functioning properly

Sign off on the safety component replacement

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.

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! Obey the safety instructions of the drive. If you ignore them, injury or death, or damage to the equipment can occur. If you are not a qualified electrical professional, do not do installation, commissioning or maintenance work.

Drive stopped and electrical safety precautions followed

Drive module removed from the cabinet

Support legs of the pedestal opened

Two screws that fasten the fan assembly plate undone

Power supply wires of the fans disconnected

Fan assembly removed from the drive module

Fastening screws of the fan(s) undone and fan(s) removed from the assembly plate

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.

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.
