This section provides the temperature, humidity, shock, and vibration specifications. Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Above 1000ft. (305 meters), the maximum temperature is derated linearly by 1°C every 1000 ft.

2.9.1Drive case temperature

Drive case temperature should be measured at the location indicated in Figure 3 on page 23.

Operating (drive case temperature)	0° to 75°C (32° to 167°F)
Non-operating (ambient *)	–40° to 70°C (–40° to 158°F)

* Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.
