• 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 Hard Disk have a fixed lifetime, but that accidents

can always occur. Therefore, be sure to back up your Hard Disk's data regularly, or

prepare another Hard Disk 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

[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.

SEE

Installation/uninstallation of the front module and the control box (page 11)

• Make sure to turn off the power supply before using the switches. Adjusting the

switches while power is supplied may cause errors.
