12 Medalist 8641, 6531, 4321, 3221 and 2110, Rev. B 1.8 Environmental tolerances 1.8.1 Ambient temperature Operating 5° to 55°C (41° to 131°F) Nonoperating -40° to 70°C (-40° to 158°F) Note. Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters). Operating ambient temperature is defined as the temperature of the environment immediately surrounding the drive. 1.8.2 Temperature gradient Operating 20°C/hr (68°F/hr) max, without condensation Nonoperating 20°C/hr (68°F/hr) max, without condensation 1.8.3 Humidity 1.8.3.1 Relative Humidity Operating 8% to 90% noncondensing (10% per hour max) Nonoperating 5% to 95% noncondensing (10% per hour max) 1.8.3.2 Wet bulb temperature Operating 29.4°C (84°F) max Nonoperating 29.4°C (84°F) max 1.8.4 Altitude Operating -122 m to 3,048 m (-400 ft to +10,000 ft) Nonoperating -122 m to 12,192 m (-400 ft to +40,000 ft) 1.8.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis.
