Heatsinks; Capacitors; Capacitor Replacement; Other Maintenance Actions - ABB ACS800 Series Hardware Manual

Heatsinks

The heatsink fins of the power modules pick up dust from the cooling air. The module
runs into overtemperature warnings and faults if the heatsinks are not clean. In a
"normal" environment (not especially dusty nor clean) the heatsinks should be
checked annually, in a dusty environment more often.
Whenever necessary, clean the heatsinks as follows:
1. Remove the cooling fan (see section
2. Blow dry clean compressed air from bottom to top and simultaneously use a
vacuum cleaner at the air outlet to trap the dust. Note: Prevent the dust from
entering adjoining equipment.
3. Refit the cooling fan.

Capacitors

The lifespan depends on the operating time of the converter, loading and ambient
temperature. Capacitor life can be prolonged by lowering the ambient temperature.
It is not possible to predict capacitor failure. Capacitor failure is usually followed by
damage to the unit and an input cable fuse failure, or a fault trip. Contact ABB if
capacitor failure is suspected.

Capacitor replacement

Contact an ABB service representative.

Other maintenance actions

Power module replacement

To replace converter modules, follow the instructions on module removal and
refitting given in section
