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 Daikin.

Heatsink

Sinceadustyheatsinkislessefcient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 Figure 12 and Figure 13).
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

Frame Sizes R1—R4
To replace the fan:
1. Remove power from drive.
2. Remove drive cover.
3. For Frame Size:
— R1, R2: Press together the retaining clips on the fan
cover sides, and lift.
— R3, R4: Press in on the lever located on the left side
of the fan mount, and rotate the fan up and out.
4. Disconnect the fan cable.
5. Install the fan in reverse order.
