The U389 energy meter acquires active energy in 4-wire 3-phase systems.
Import energy is transmitted to the logging system via a pulse output (S0) and
can be read directly from a 7-digit drum-type counter mechanism. Current
transformers connected with reversed polarity and direct connection are
recognized and displayed as errors.
