dust and water into the housing is possible.This is prevented effectively by inserting
the double sealed intermediate frame [2] between the plug/socket connector [1] and
the housing of the device.The enclosure protection of the device (IP 68) will not be
affected, even if the electrical connection [1] is removed.
