before performing any maintenance on the
equipment. Ignoring the safety instructions can 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 accumulate dust from the cooling air. Since a dusty heatsink is less
efficient at cooling the drive, overtemperature faults become more likely. In a
“normal” environment (not dusty, not clean) check the heatsink annually, in a dusty
environment check more often.
Clean the heatsink as follows (when necessary):
1. Remove power from drive.
2. Remove the cooling fan (see section
Drive module fan replacement
on
page
1-290
).
