1.8.4 Relative humidity
Operating 8% to 80% noncondensing
Maximum wet bulb 29.4°C (84.9°F)
Operating gradient, max 10% per hour
Nonoperating 5% to 95% noncondensing
Maximum wet bulb 35°C (95.0°F)
1.9 Shock and vibration
All shock and vibration specifications assume that the inputs are measured
at the drive mounting screws. Shock measurements are based on an
11-msec, half sine wave shock pulse, not to be repeated more than twice
per second.
During normal operating shock and vibration, there is no physical dam-
age to the drive or performance degradation.
During abnormal operating shock and vibration, there is no physical
damage to the drive, although performance may be degraded during the
shock or vibration episode. When normal operating shock levels resume,
the drive meets its performance specifications.
During nonoperating shock and vibration, the read/write heads are
positioned in the shipping zone.
