This section describes the mechanical construction of the ZxD400xT meter
and shows the most common connection diagrams.
The internal construction of the meters is not described here, since they are
protected following calibration and official certification on delivery by a
manufacturer and certification seal. It is not permitted to open the meters
after delivery. The front door is only secured with a utility seal and can be
opened to operate the reset button, to change the battery, to exchange the
tariff faceplate with connection diagram or to fit or remove a communication
unit (see figure 22 and separate user manuals for the communication units
available).
The following drawing shows the meter components visible from outside.
