cause injury or death.

Maintenance intervals

If installed in an appropriate environment, the drive requires very little maintenance.
This table lists the routine maintenance intervals recommended by ABB.

Heatsink

The heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean. In a normal
environment, the heatsink should be checked annually, in a dusty environment more
often.
Clean the heatsink as follows (when necessary):
1. Remove the cooling fan (see section
2. 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
the dust entering adjoining equipment, perform the cleaning in another room.
3. Replace the cooling fan.
