• Close the CTs coil again. The red wire of this CT must be connected to contact 10 (CTR1) of the DinRail.
WARNING! Make sure the direction of the arrow illustrated at the CT
terminals to the load. Reconnect the current conductor.
• Repeat the process for the other two phases (L2, L3).
Power lines L1 L2 L3 installation
• Power the 2A protective circuit breakers from the main circuit
breakers of the electrical panel
• Connect the output of each of the above circuit breakers with the
terminal 1(L1), terminal 2(L2) and terminal 3(L3) respectively of the
DinRail.
WARNING! Make sure that the sequence of phases 1, 2 and 3 of
the DinRail is strictly L1, L2 and L3, otherwise measurements will be
incorrect.
• Connect the neutral conductor of the electrical panel to contact
4(N) of the DinRail.
• Check the entire procedure again before completing the
installation (sequence of the phases of the inputs of the DinRail,
sequence of the Current Transformers’ connection, direction of the
arrow of each CT).
Upon completion of the electrical installation of DinRail, the electrical
panel should appear as below:
