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.
Internal Switches
To operate the internal switches, uninstall the control box and the front module.
• Make sure to turn off the power supply before using the switches. Adjusting the
switches while power is supplied may cause errors.
