Medalist 4342, 3232, 2122, 1722 and 1012 Product Manual 13 1.8.3.2 Wet bulb temperature Operating 28.9°C (84°F) max Nonoperating 28.9°C (84°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 document when subjected to a maximum operating shock of 5.0 Gs (based on half-sine shock pulses of 11 msec, as specified in MIL-STD-202F). Shocks are not to 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 subsequently put into operation is 75 Gs (based on nonrepetitive half-sine shock pulses of 11 msec duration, as defined in MIL-STD-202F). 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. 1.8.6.1 Operating vibration The following lists the maximum vibration levels that the drive may experience while meeting the performance standards specified in this document. 5-22 Hz 22-350 Hz 0.02-inch displacement to 5.0 Gs 0.50 Gs acceleration (zero to peak)
