and non-transferable. Nameplate for meters with non-transferable cover is marked on the non-
transparent part of main cover by means of laser marking technology during the meter
manufacturing process. This ensures that all marks and inscription are clear, non-erasable and
non-transferable.
The nameplate bears all the necessary information according to EN 50470-1 and Directive
2004/22/EC, as well as identification of main data, displayed on LCD. Example of nameplate is
provided in Figure 5-3. Meter serial number is displayed as barcode (by default, barcode type
Interleaved 2/5). Additional QR (DataMatrix) code which contains the meter technical information is
printed on the nameplate.

5.3 Terminal block
The terminal block with all meter connections is situated behind the terminal cover. Terminal block
made from highly mechanically resistant and fire retardant insulation material and conform to the
requirements of standard DIN 43857. One utility seal in the fixing screw of the terminal cover
prevent unauthorized access to the phase connections and therefore also prevent unrecorded
energy consumption.
Current and voltage terminals can be made of zinc-plated iron or nickel-plated brass (copper) and
it provides the ability to add copper or aluminium wires without oxidation process. Terminal
assures the same quality of the contact irrespective of the shape of the connection conductor (a
compact wire, a stranded wire, greater or smaller cross-sections).
