(1) The basic instrument is powered from L1, L2, L3 and N (4-wire version) or L1, L2, L3 (3-wire version). The presence of only one of the three phases (4-wire version) or two phases (3-wire version) ensures the normal counting and displaying operations.
(2) The serial port is powered from L1 and N (4-wire version) or L1 and L2 (3-wire version). The communication function is ensured only if the L1 phase (or L1 and L2 for 3-wire) is present and within the specified range.
