• When using any of the PL’s optional devices, be sure to check that device’s
specifications for any special conditions or cautions that may apply to its use.
• As a Hard Disk has a lifetime, it might be broken during operation. To prepare an
expected Hard Disk error, we recommend you take backup the data you need or
keep an alternate Hard Disk to exchange.
• It may cause a fatal error that the Hard Disk is used in a high temperature and
high moisture environment. We recommend that an appropriate environment be
29°C in Wet-bulb temperature (Maximum). This temperature, for example, is
equal to 64%RH (Relative Humidity) at 35°C, or 44%RH at 40°C.

*1 The front face of the PL unit, installed in a solid panel, has been tested using conditions
equivalent to the standards shown in the specification. Even though the PL unit’s level of re-
sistance is equivalent to these standards, oils that should have no effect on the PL can possi-
bly harm the unit. This can occur in areas where either vaporized oils are present, or where
low viscosity cutting oils are allowed to adhere to the unit for long periods of time. If the
PL’s front face protection sheet becomes peeled off, these conditions can lead to the ingress
of oil into the PL and separate protection measures are suggested. Also, if non-approved oils
are present, it may cause deformation or corrosion of the front panel’s plastic cover. There-
fore, prior to installing the PL be sure to confirm the type of conditions that will be present
in the PL’s operating environment.
If the installation gasket is used for a long period of time, or if the unit and its gasket are re-
moved from the panel, the original level of the protection cannot be guaranteed. To maintain
the original protection level, be sure to replace the installation gasket regularly.
