2.10Environmental specifications

2.10.1Ambient temperature

Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature, measured on baseplate, should not exceed 90°C (194°F) within the operating ambient conditions.

Operating	Extreme: -30° to 85°C (-86° to 185°F)
	Rugged: -20° to 75°C (-68° to 167°F)
Nonoperating	–40° to 95°C (–140° to 203°F)

2.10.2Temperature gradient

Operating	20°C/hour without condensation
Nonoperating	30°C/hour

2.10.3Humidity

2.10.3.1Relative humidity

Operating	5% to 90% noncondensing (30% per hour max gradient)
Nonoperating	5% to 95% noncondensing (30% per hour max gradient)

2.10.3.2Wet bulb temperature

	Operating	30°C (86°F max)
	Nonoperating	40°C (104°F max)
2.11	Altitude
Operating (Extreme models: -30°C to 85°C)			–304.8 m to 5,500 m (–1000 ft to 18,100 ft)
Operating (Rugged models: -20°C to 75°C)
Nonoperating (below mean sea level, max)			–304.8 m to 12,192 m (–1,000 ft to 40,000 ft)

2.11.1Shock

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.

2.11.1.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 300 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second. For 11 msec shock duration, these drives will withstand operating shock up to 150 Gs.
