To ensure everything works correctly, chargers must be configured after being added to a location. This ensures the charger is ready for any load management and billing purposes later on.

First, make sure your charger is added to a location and that the location itself is correctly configured.

If you're an installer, you can save time by preparing the location and its chargers beforehand. Read our guide on this for more details.

Things can get a bit technical, so here's an explanation of all the questions we ask during configuration.

This means the grid type the charger is connected to.

TN (Star Y, PE conductor)

Common in urban areas in western Europe. Neutral (N) and earth (PE) come from the grid. PE is bonded to the transformer.

TT (STar Y, Earth Rod)

Common in rural areas. N comes from the grid, but PE is local. The building has its own earth rod.

IT (Delta Δ, No Neutral)

Common in the nordics and Belgium. The grid has no N, phases are isolated and the building has its own earth rod.

This refers to the charger's physical circuit breaker and its rating.

This refers to the electronically set current limit of the charger. We advise 80% of the circuit breaker rating.

This means which phases of the charger are connected to which phases of the building.

For instance, if phase 1 of the building is highly occupied, you may want to connect phase 1 of the charger to a different phase of the building.

Here's a table to explain phase rotations and which charger phase is connected to which phase of the building.
