On the three-phase meter with APS (Auxillary Power Supply) the S0-output is not available. S0 output can then
only be achieved as a module interface.

Auxillary Power Supply
The meter can optional be configured with an Auxillary Power Supply (APS) functionality. The function allows to
supply the meter with 230VAC on a separate input as shown in Figure 12. The functionality is usefull when a
external breaker is installed before the meter in an installation.

Figure 12: APS functionality.
When the meter is configured for APS functionality it doesn’t have a S0 output, as the connector is used for the
230 V APS input.
