The front face of the ST unit, installed in a solid panel, has been tested using
conditions equivalent to the standards shown in the specification. Even though the ST unit’s
level of resistance is equivalent to these standards, oils that should have no effect on the ST
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 ST’s front face protection sheet becomes peeled off, these conditions can lead to the
ingress of oil into the ST 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 ST be sure to confirm the type of
conditions that will be present in the ST’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
maintain the original protection level, be sure to replace the installation gasket
regularly.
