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 Daikin .

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
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 .
4 . Replace the cooling fan .
5 . Restore power .
NOTE: If there is a risk of the dust entering adjoining
equipment, perform the cleaning in another room .

Drive Module Fan Replacement
The drive module fan cools the heatsink . Fan failure can be
predicted by the increasing noise from fan bearings and the
gradual rise in the heatsink temperature in spite of heatsink
cleaning . If the drive is operated in a critical part of a process,
fan replacement is recommended once these symptoms start
appearing . Replacement fans are available from Daikin . Do not
use other than Daikin specified spare parts.
