ABB Motor Control Drive ACS380-040S-04A0-4

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 or maintenance work.

Drive stopped and electrical safety precautions followed

Fan cover opened using a suitable flat screwdriver

Fan cover carefully lifted out of the drive

Fan power cable removed from the cable slot in the drive

Fan clips freed and fan removed from the fan cover

New fan installed into the fan cover ensuring correct air flow direction

The drive module heatsink fins pick up dust from the cooling air. The drive runs into overtemperature warnings and faults if the heatsink is not clean. When necessary, clean the heatsink as follows.

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.

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

2. Remove the module cooling fan(s). See the separate instructions.

3. Blow dry, clean and oil-free compressed air from bottom to top and simultaneously use a vacuum cleaner at the air outlet to trap the dust. If there is a risk of dust entering adjoining equipment, do the cleaning in another room.

4. Reinstall the cooling fan.;
