Notes :
• the values transmitted - energy, current, voltage, frequency - are instant values, while power values are the average values within the transmission interval
• “error flag” is a diagnostic variable used to communicate an overflow condition which makes the measured data invalid:

1P system 3P system • N.A. (not available): the bit cannot be set because the relevant
measurement is not defined, bit = 0.
• Frequency out of range is set when occurs an overflow or an under -
flow of the frequency measured by measuring module.
• In system 3P, monitored voltages are the L-N voltages referred to a
virtual neutral.
