Environmental specifications
2.9.1
Ambient temperature
Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.
Actual drive case temperature should not exceed
69°C (156°F) within the operating ambient conditions. Rec-
ommended measurement locations are shown in See Figure 6 on page 27.
Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet
(3,048 meters).
