6 Technical data
6.1 Generalities
The stated technical data only refer to the measuring value display unit EA16
and never take into account the properties of the connected measuring trans-
ducer.
The EA16 is designed as a component for panel installation and is only supplied
fully assembled and wired. Please see the supplied electro-technology docu-
ments of the respective panel for information about the electrical connection.
