Structure

*1. The front face of the OT unit, installed in a solid panel, has been tested using conditions

equivalent to the standards shown in the specification. Even though the OT unit’s level of

resistance is equivalent to these standards, oils that should have no effect on the OT 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 OT’s front face protection sheet is peeled off, these conditions can lead to the ingress of

oil into the OT and separate protection measures are suggested.

Also, if non-approved oils are present, they may cause deformation or corrosion of the front

panel’s plastic cover. Therefore, prior to installing the OT be sure to confirm the type of

conditions that will be present in the OT’s operating environment.

If the installation gasket is used for a long period of time, or if the unit and gasket are

removed from the panel, the original level of the protection can be compromised. To

maintain the original protection level, be sure to replace the installation gasket regularly.
