Keep your ACH580 cool!

The ABB recommended replacement time for the main cooling fan is every 6 years and every 3 years for the auxiliary cooling fans in the IP55 units. Making sure these fans keep turning is important to ensure the continued functioning of these drives.

This guide will cover how to replace the main and auxiliary fans for the ACH580 frame sizes R1 and R2.

First, stop the drive and disconnect it from the power line. Wait for 5 minutes and then make sure by measuring that there is no voltage.

Then lever the fan assembly off the drive frame with for example a screwdriver (2a) and pull out the fan assembly (2b) until you can unplug the fan power supply wires from the fan assembly (2c).

Install the fan assembly in reverse order

.R1…R2: Put the connector and extra length of wires in the groove so that the wires do not get caught in the revolving fan.

R3: Put the extra length of wires under the fan assembly so that the wires do not get caught in the revolving fan.


Next, we’ll move on to replacing the auxiliary fans inside the IP55 variants of these drives.

Again and most importantly stop the drive and disconnect it from the power line. Wait for 5 minutes and then make sure by measuring that there is no voltage.

Remove the control panel: Press the retaining clip of the IP55 panel cover (2a) and open the cover (2b). Press the retaining clip of the control panel at the top (2c) and pull it forward from the top edge (2d).

Remove the front cover: Loosen the retaining screws with a screwdriver (3a) and lift the cover from the bottom outwards (3b) and then up (3c).

Unplug the fan power supply wires from the drive.

Remove the fingerguard: Insert a screwdriver into the hole of the finger guard (5a), bend the front edge of the finger guard a little away from the drive frame with the screwdriver (5b) and pull the fingerguard out of the groove (5c). 6. Pull off the fan.

Install the new fan assembly in reverse order. Route the wires around the pins. Note: Make sure that the arrow on the fan points to the same direction as the arrow on the drive frame.


There you have it. Your drive should be good to go for another few years.
