Environmental specifications
3.9.1
Ambient temperature
Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. 
Actual drive case temperature should not exceed 60°C (140°F) within the operating ambient conditions.
Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet 
(3,048 meters). 
3.9.2
Temperature gradient
Operating:
20°C per hour (68°F per hour max), without condensation
Nonoperating:
20°C per hour (86°F per hour max)
3.9.3
Humidity
3.9.3.1
Relative humidity
Operating:
5% to 95% noncondensing (20% per hour max)
Nonoperating:
5% to 95% noncondensing (20% per hour max)
3.9.3.2
Wet bulb temperature
Operating:
37.7°C (99.9°F max)
Nonoperating:
40.0°C (104.0°F max)
3.9.4
Altitude
Operating:
–60.96 m to 3,048 m (–200 ft. to 10,000+ ft.)
Nonoperating:
–60.96 m to 12,192 m (–200 ft. to 40,000+ ft.)
3.9.5
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.
3.9.5.1
Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum 
operating shock of 70 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more 
than once every 2 seconds.
3.9.5.2
Nonoperating shock
The nonoperating shock level that the drive can experience without incurring physical damage or degradation 
in performance when subsequently put into operation is 400 Gs based on a nonrepetitive half-sine shock pulse 
of 2 msec duration.
Operating:
5° to 55°C (41° to 131°F)
Nonoperating:
–40° to 70°C (–40° to 158°F)
