- Set the available current on the mains connection under Current limit of the mains connection (L1/L2/L3) [A].
- Set the safety distance to the maximum value under Safety margin for external load (L1/L2/L3) [A].
- Set the assumed load in case of failure under Fallback value of the external load (L1/L2/L3) [A]. If the value 9999 is input, all charging points will be switched off in case of failure.
- Set the type of dynamic load management under Topology of the external meter.
- Under Meter configuration (external meter), select the meter for the external measurement.
