Maintenance

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
Cooling fans
).
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 inverter modules employ several electrolytic capacitors. Their lifespan is at least
90 000 hours depending on the operating time of the drive, 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.
Reforming
Reform (re-age) spare part capacitors once a year according to
ACS 600/800
Capacitor Reforming Guide
(code: 64059629 [English], available through your local
ABB representative.
Capacitor replacement
Contact an ABB service representative.
Other maintenance actions
Power module replacement
To replace power modules (i.e. supply and inverter modules), follow the instructions
on module removal and refitting given in the chapter
Electrical installation
