Chapter 5 Maintenance

5-5

• The gasket must be inserted correctly into the groove for the LT’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 LT unit.

• The upper surface of the gasket should protrude approximately 2.0 mm out from

the groove. Be sure to check that the gasket is correctly inserted before installing

the LT into a panel.
