The air-flow pattern with which the temperature guidelines above were
generated is shown in Figure 6 (opposite direction). Local average air
velocity was 0.61 msec (120 lfpm) and inlet air temperature to the drive was
30°C (86°F), plus a 5°C temperature rise in the test enclosure (35°C ambient
local to the drive).
The maximum allowable HDA case temperature is 60°C (see Figure 13).
