Table 3: PCB and HDA temperatures
Note.
[1] The air-flow pattern with which the temperature guidelines in Column 2 were generated is shown in
Figure 11. Local average air velocities were 200 lfpm and inlet air temperature to the drive was 86°F
(30°C), plus a 9°F (5°C) temperature rise in the test enclosure (86°F/30°C ambient local to the drive).
[2] The temperatures in Column 1 are calculated and may not reflect actual operating values. Sufficient
cooling air may be required to ensure that these values are not exceeded.
[3] Measure HDA temperature at point labeled “HDA Temp. Checkpoint” on Figure 4.
