• The gasket must be inserted correctly into the groove for the ST’s moisture
resistance to be equivalent to IP65f.
• Since the gasket is flexible but not elastic, be careful not to stretch it
unnecessarily, as doing so could tear the gasket.
• Be sure the gasket’s seam is not inserted into any of the unit’s corners, only in
the straight sections of the groove. Inserting it into a corner may lead to its
eventually tearing.
• To ensure stable resistance against dust and moisture, insert the gasket so that
the seam is at the bottom of the ST unit.
• The upper surface of the gasket should protrude approximately 2.0mm[0.08in]
out from the groove. Be sure to check that the gasket is correctly inserted before
installing the ST into a panel.
