Maintenance
Warning! Read Safety on page 1-3 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
JCI
.
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 1-292 ).
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.
