PL-DU6900/PL-DU7900 User Manual
*1 The front face of the DU unit, installed in a solid panel, has been tested using conditions
equivalent to the standards shown in the specification . Even though the DU unit’s level of
resistance is equivalent to these standards, oils that should have no effect on the DU can
possibly 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 DU’s front face protection sheet becomes peeled off, these conditions can lead to the
ingress of oil into the DU 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. Therefore, prior to installing the DU be sure to confirm the type of conditions that
will be present in the DU’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, you need to replace the installation gasket regularly.
*2 Be sure to use your country's applicable standard.
When using the DU with an optional unit, be sure to also confirm the
option unit’s specifications.
