2.1.8Environmental specifications

2.1.8.1Case temperature

Actual drive case temperature should not exceed 75°C (167°F). Recommended measurement locations are shown in Figure 3 on page 18.

Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 44°C (112°F) at 10,000 feet (3,048 meters).

2.1.8.2Temperature gradient

Operating	20°C per hour (68°F per hour max), without condensation
Nonoperating	30°C per hour (86°F per hour max)

2.1.8.3Humidity

2.1.8.3.1Relative humidity

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

2.1.8.3.2Wet bulb temperature

Operating	37.7°C	(99.9°F max)
Nonoperating	40.0°C	(104.0°F max)

2.1.8.4Altitude

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.)

2.1.8.5Shock

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.

2.1.8.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 63 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.

2.1.8.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse of 2 msec duration.

2.1.8.6Vibration

All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis.
