CONNECTION OF THE VOLTAGE AND CURRENT MEASURES
The instrument is auto-fed by V1 and V2 mains voltages. Use cables with a max. section of 2.5
mm
2
and connect them to the terminals identified with VOLTS INPUT, according to the wiring
diagram shown in the figure. WARNING: threshold: 60-500VAC phase-phase. You need to use
3 CTs with a 5A secondary. Connect the amperometric signal from the CTs to the terminals
marked with CURRENT INPUT according to the diagram shown in the figure. Use cables with
the proper section according to the used CT capacity and to the distance.
Note: the CT secondary must always be short-circuited when it is not connected to the instrument
to avoid damage and risks for the operator.
ALWAYS KEEP TO THE PHASE MATCHING BETWEEN VOLTMETRIC AND AMPEROMETRIC
SIGNALS. Failure to follow both the matching and the wiring diagrams may lead to measurement
errors.
