To prevent high potentials from
occurring at the transformer
terminals, all S2 terminals of
the transformers should be
earthed.

outputs
Passive pulse outputs (open
collector), Class A compliant
IEC 62053-31
P1 – programmable
pulse output (function
and number of pulses)
P2 – energy consumption indi-
cation (3200 pulse/kWh)
COM – common ground of P1
and P2 outputs.
Maximum load of a single
output pulse:
voltage ≤30 V current ≤20 mA
