3.9.2

Humidity

3.9.2.1 Relative humidity
Operating: 5% to 90% noncondensing (30% per hour max)
Nonoperating: 5% to 95% noncondensing (30% per hour max)
3.9.3

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.)
3.9.4

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.
3.9.4.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum
operating shock of 70 Gs (read) and 40 Gs (write) based on half-sine shock pulses of 2ms. Shocks should not
be repeated more than two times per second.
3.9.4.2 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 300 Gs based on a nonrepetitive half-sine shock pulse
of 2ms duration.
3.9.5

Vibration

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.
3.9.5.1 Operating vibration
The maximum vibration levels that the drive may experience while meeting the performance standards speci-
fied in this document are specified below.
5–22 Hz 0.25 Gs
22–350 Hz 0.50 Gs
350–500 Hz 0.25 Gs
20 - 1500Hz
