• Be sure to confirm the installation condition of the gasket when you install the unit in
the panel. The gasket must be inserted correctly into the groove for the PS-A unit’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 PS-A unit.
