1.8.3 Humidity

1.8.3.1 Relative Humidity
Operating 5% to 90% noncondensing (30% per hour max)
Nonoperating 5% to 90% noncondensing (30% per hour max)
1.8.3.2 Wet bulb temperature
Operating 29.4°C (84°F) max
Nonoperating 40.0°C (104°F) max

1.8.4 Altitude

Operating –61 m to 3,048 m (–200 ft to 10,000+ ft)
Nonoperating –61 m to 12,192 m (–200 ft to 40,000+ ft)

1.8.5 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.
1.8.5.1 Operating shock
These drives comply with the performance levels specified in this docu-
ment when subjected to a maximum operating shock of 5.0 Gs (based
on half-sine shock pulses of 11 msec. Shocks should not be repeated
more than two times per second.
1.8.5.2 Nonoperating shock
The nonoperating shock level that the drive can experience without
incurring physical damage or degradation in performance when subse-
quently put into operation is 75 Gs (based on nonrepetitive half-sine
shock pulses of 11 msec duration) or 200 Gs (based on nonrepetitive
half-sine shock pulses of 2 msec duration).

1.8.6 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.
