• The environment specifications given here are for a unit installed
in a PL, that is built into a solid panel.
• Pro-face does not guarantee the preservation of any data stored
on the HDD unit if the HDD unit has an accident, malfunctions or
is damaged in any way. Therefore, the regular backing up of im-
portant HDD unit data to either a floppy disk, or other type of suit-
able magnetic media is strongly recommended.
• This HDD unit has a finite usage lifetime. The lifetime figure given
in this document’s Features is for reference, and the regular ex-
changing of the current HDD unit for a new HDD unit is strongly
advised.
• Using the HDD unit in an environment that is excessively hot and/
or humid will shorten the disk’s usage lifetime. A wet bulb tem-
perature of 29
o
C or less is recommended. This is equivalent to
the following data.
•
In order to extend the lifetime of the hard disk, Pro-face recom-
mends you set the Windows [Control panel]-[Power Manage-
ment 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.
