2.8.1
Ambient temperature
Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.
Actual drive case temperature should not exceed
Actual drive case temperature should not exceed
70°C (158°F) within the operating ambient conditions. Case
temperature of the drive operating at 60°C ambient may hit a maximum of 70°C at certain parts of the casing.
Above 1,000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet.
