Current transformers connection:
Connect the the amperometric signal coming from the fl exible CT output(s) to the terminals marked I1, I2, I3 (CURRENT INPUT) of the instrument according to the applicable diagrams
that follow. Respect scrupulously the phase pairing between the voltage and current signals (RST) and the direction of insertion of the CT (S1-S2). Failure to comply with such
correspondence and connection diagrams will result in measurement errors.
ATTENTION: Use exclusively Electrex fl exible split current transformers of the series FCTS. Do not use standard current transformers (/ 1 / 5A), their use will damage the
instrument.
