With transformer
If a transformer is used to convert the 3 x 230 V delta connection to a standard 3 x 400 V star with
neutral, then the charging station’s power supply can be connected as usual. Please refer to the
pictures on previous pages for this. The connection in the distribution cabinet is still a little different,
as shown in the diagram below.
When a transformer is used in combination with a 3 x 230 V delta topology, the purchase
of an additional Smappee Power box is required. This will be placed inside the distribution
panel. In this case, the Power Box inside the EV Wall becomes redundant and both RJ10
cables should be disconnected.
