Electrex EXA TR D6 Manual de instalação
Voltage connection: Use cables with max cross-section of 2,5 mm
the applicable diagrams that follow.
Current connection: It is necessary to use external CTs with a primary rating adequate to the load to be measured and with a 5A or 1A secondary rating. 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 2,5 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.
Scrupulously respect the matching of phase between the voltage signals and current signals (RTD) and the direction of insertion of CT (P1-P2 and S1-S2). Failure to comply with this
correspondence and connection diagrams gives rise to measurement errors. (*) The grounding of S2 must be close to the CT and not near the instrument.
