The meter can be used with single-phase or 3-phase line (3 or 4 wires);
please scrupulously respect the wiring diagram. The input configuration
must be completed with the keyboard programming of the chosen con-
nection type as well as of any external CT or VT ratios.

OUTPUTS
In the wiring diagrams always appear the configuration with pulse output
and RS485 or M-bus communication.
For the versions that are not designed for RS485 or M-Bus communication
and pulse output, you do not have to take into consideration the relevant
connections
.
