Environmental Specifications
• When using any of the PL’s optional devices, be sure to check that device’s specifica-
tions for any special conditions or cautions that may apply to its use.
• Be aware that not only does the HDD/SSD have a fixed lifetime, but that accidents
can always occur. Therefore, be sure to back up your HDD/SSD’s data regularly, or
prepare another HDD/SSD unit that can be used for backup.
• The Hard Disk lifetime given here may be reduced due to unforeseen environmental
factors, however, generally speaking, the disk should last for 20,000 hours (of opera-
tion) or approximately 5 years, whichever comes first at an operating temperature of
20°C and 333 hours of operation per month. (HDD access frequency of 20% or less)
• Using the Hard Disk in an environment that is excessively hot and/or humid will
shorten the disk’s usage lifetime. A wet bulb temperature of 29°C or less is recom-
mended. This is equivalent to the following data.
• In order to extend the lifetime of the hard disk, Pro-face recommends you set the
Windows
®
2000’s [Control panel]-[Power Management option]-[Turn off hard disks]
selection or the Windows
®
XP’s [Control panel]-[Performance and Maintenance]-
[Power Management option]-[Turn off hard disks] selection to turn the hard disk off
when the unit is not being operated. A setting of 5 minutes is recommended.
• Do not vibrate the hard disk continuously at the same frequency. Doing so may cause
the hard disk to reduce transfer speeds or stop temporarily.
• Weight increases by about 1.4kg with a battery unit. Please refer to PL3000 Series Hardware
Manual for other specifications.
