Feeding and fuse protection

Fusing charging station

Maxem is a control system that regulates the load of the charging station. Therefore, it can

be calculated according to the NEN 1010 with a lower equal time factor*. Maxem makes

sure that the charging station is less loaded when there is more charge in the house. The

charging station can therefore be fused to a value higher than normal, but not higher than

the threshold value of the main power supply terminal.

*(NEN 1010:2015 722.311) The equal time factor is the ratio between the maximum simultaneous load of a

group of electrical devices or consumers within a certain period and the sum of their individual maximal loads

within the same period.

230V power supply from Maxem

Maxem measures the power supply as follows:

•

Amperage: divisible current coils measure the current through the phase wires.

•

Voltage: internal voltmeter in Maxem with the voltage from the 230V power supply.

For a correct measurement it is necessary to know from which phase Maxem is fed. In

Maxem it is standardly installed that the supply is on Phase 1 (L1).

Hang Maxem on a clean, moisture-free wall. Use the supplied mounting plate and

screws for this. Take into account sufficient space around the Maxem.
