The open terminal compartment can be closed using a protective cover (not

5.3.4 Double sealed intermediate frame
When removing the electrical connection or due to leaky cable glands, ingress of
dust and water into the housing may occur. 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.
