Energy counter - power recovery
The energy fed back to the mains can be detected by weighted pulses at the S0 output. For
this purpose, S0+ must be supplied with an external voltage. S0- serves to trigger a suitable
counter input. A current limitation must be made by an external configuration.
The scaling of the weighted pulses is 1000 pulses/kWh.
