Heatsink; Fans - ABB ACS880-07 Hardware Manual

Heatsink

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! Obey the instructions in chapter
ignore them, injury or death, or damage to the equipment can occur.
WARNING! Use a vacuum cleaner with antistatic hose and nozzle. Using a
normal vacuum cleaner creates static discharges which can damage circuit
boards.
1. Stop the drive and do the steps in section
16 before you start the work.
2. Remove the drive module from the cabinet.
3. Remove the module cooling fan(s). See section
4. Blow dry clean compressed air (not humid) from bottom to top and simultaneously use
a vacuum cleaner at the air outlet to trap the dust. Note: If there is a risk of dust
entering adjoining equipment, perform the cleaning in another room
5. Refit the cooling fan.

Fans

The lifespan of the cooling fan of the drive depends on the running time of the fan, ambient
temperature and dust concentration. See the firmware manual for the actual signal which
indicates the running time of the cooling fan. Reset the running time signal after a fan
replacement.
Replacement fans are available from ABB. Do not use other than ABB specified spare
parts.
