Technical Data
3.2.6.3 S0 interface
The S0 interface transmits pulses between a pulsing counter and a tariff metering unit. It is a galvanically isolated
transistor output. It is designed according to DIN EN 62053-31:1999-04 (pulse output devices for electromechanical
and electronic meters).
NOTE
The S0 interface pulse rate can be chosen in three unit intervals (500, 1,000 and 2,000 pulses/kWh) for
Powador 7700 to 9600 inverters.
3.2.6.4
Digital input
If Powador protect is installed as a central grid and system protection, the fail-safe disconnection of suitable Pow-
ador inverters from the public grid can be initiated by a digital signal instead of tie circuit-breakers. This requires the
inverters in the photovoltaic system to be connected to the Powador protect. For information on the installation
and use see this manual, the Powador protect manual and the instructions for use of the Powador protect on the
web site.
