Maintenance 123
Heatsink
The 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!
Follow the safety instructions, page
. Ignoring the instructions
can cause physical injury or death, or damage to the equipment.
WARNING!
Use a vacuum cleaner with antistatic hose and nozzle. Using a
normal vacuum cleaner creates static discharges which can damage circuit
boards.
1. Disconnect the drive from the power line. Lock the main disconnecting device and
ensure by measuring that there is no voltage.
2. Remove the cooling fan(s). See section
below.
3. Blow 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.
4. Refit the cooling fan.
Fans
The lifespan of the cooling fans of the drive depend 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.
