PL-5910 Series User Manual
2.1.2 Environmental
• When using any of the PL unit’s optional devices, be sure to
check that device’s specifications for any special conditions or
cautions that may apply to its use.
• Since the PL unit’s hard disk drive (HDD) is a consumable item,
i.e. it has a limited lifetime, be sure to back up its data regularly
and prepare a spare HDD unit.
• The Hard Disk lifetime given here may be reduced due to un-
foreseen environmental factors, however, generally speaking,
at an operating temperature of 20
o
C and assuming 333 hours of
operation (HDD motor is ON) per month (an access time of 20%
or less), the HDD unit should last for 20,000 hours (power is
ON) or approximately 5 years, whichever comes first.
• 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
o
C or less is recommended. This is equivalent
to the following data.
