8. Connection Current Transformers and Sensorbox
In order to measure the current, Current Transformers are used (type
SCT013-00, one for each phase). Clip them around the L1, L2 and L3
wires and plug the other end into the Sensorbox.
The Current Transformers should be placed where the Mains connection
enters the building. This way it will be possible to measure the total
current per phase and send this information through the Sensorbox to the
Smart Box (see picture page 25)
The data cable on the Sensorbox should be connected to terminals A
(white), B (yellow), +12V (brown) and GND (green).

NOTE:
The date cable between Sensorbox and Smart Box is not
supplied. You can use a standard UTP cable or 4 x 0,25 mm
data cable.
Connect the data cable in the charging station with the supplied 4 pole
connector. Master/Slave configuration: Connect the A, B and GND
connection from the Master to the Slave(s). So A connects to A, B goes to B
etc. Make sure that the +12V wire coming from the Sensorbox is connected
to the Master Smart Box only.
