The front face of the PL unit, installed in a solid panel, has been tested using conditions
equivalent to the standard shown in the specification . Even though the PL unit’s level of
resistance is equivalent to the standard, oils that should have no effect on the PL 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 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. Therefore,
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
removed from the panel, the original level of the protection cannot be guaranteed. To main-
tain the original protection level, you need to replace the installation gasket regularly.
