Structure

*1. 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.
