Sealing
The meter has metrological seal positions on the electronics cover, display cover, terminal
compartment covers and the transducer cover caps.
Sealing can be done with adhesive labels. Alternatively the terminal compartment covers
can be sealed with wire seals.
Sealing of the parameter locking switch
The parameter locking switch and the battery of the real-time clock are protected
mechanically by a mutual joint cover. The fixing screw of this cover must be secured by a
label positioned approximately equal on the cover and cover plate.

Sealing on the Signal Processing Unit
Metrological sealing of the terminal compartment must be carried out during commission
-
ing according to national regulations.
The protection of the terminal compartment active in use must be carried out according to
the chosen explosion-proof model of the interface electronics of the Signal Processing Unit.
The following Figures show examples for protection types Ex-d “Flameproof Enclosure”, Ex-e
“Increased Safety” and Ex-i “Intrinsically Safe”.
If the manufacturer's adhesive label has been broken, sealing can also be carried out using
screws with cross or longitudinal holes and wire seals.
