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 60°C (140°F) within the operating ambient conditions.
Above 1000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet 
(3,048 meters). 
2.9.2
Temperature gradient
Operating:
20°C per hour (68°F per hour max), without condensation
Nonoperating:
20°C per hour (86°F per hour max)
2.9.3
Humidity
2.9.3.1
Relative humidity
Operating:
5% to 95% noncondensing (20% per hour max)
Nonoperating:
5% to 95% noncondensing (20% per hour max)
2.9.3.2
Wet bulb temperature
Operating:
37.7°C (99.9°F max)
Nonoperating:
40.0°C (104.0°F max)
2.9.4
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.)
** Applies to atmospheric pressure only.
2.9.5
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.
2.9.5.1
Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum 
operating shock of 1500 Gs based on half-sine shock pulses of 0.5ms. This specification does not cover con-
nection issues that may result from testing at this level.
2.9.5.2
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 1500 Gs based on a half-sine shock pulse of 0.5ms 
duration.
Operating:
5° to 60°C (41° to 140°F)
Nonoperating:
–40° to 70°C (–40° to 158°F)
