Voltage connection
Use cables with max cross-section of 2,5 mm
Current connection
It is necessary to use external CTs with a primary rating adequate to the load to be metered and with a 5A or 1A secondary rating. The number of CTs to be used (1, 2 or 3)
depends upon the type of network. Connect the CT output(s) to the terminals marked I1, I2, I3 (current input) of the instrument according to the applicable diagrams that follow.
Use cables with cross-section adequate to the VA rating of the CT and to the distance to be covered. The max cross-section for the terminals is 4 mm
N.B. The CT secondary must always be in short circuit when not connected to the instrument in order to avoid damages and risks for the operator.
Warning: The phase relationship among voltage and current signals, the P1-P2 orientation and the S1-S2 connection of the CT(s) must be carefully respected.
All disregard of this rule or of the wiring diagram leads to severe measurement errors.
