Note(
１
) In case of the low-voltage circuit (600 V or less), the secondary grounding of VT / CT is not required.
In case of the 110V / 220V / 440V direct input, VT is not required.
Note(
２
) When using with a circuit of 600 A or more, please connect the current sensor of the 5 A rated the
(CTF-5A) on the secondary side of the instrument for the current transformer (secondary 5 A).
Note(
３
) Communication output terminal (7-8, 9-10, 11-12 ,13-14) are connected internally respectively.
In case of the daisy chain, please connect in accordance with the 10 pages figure.
Termination resistor for the communication output, please use at the end of equipment.
Please connect the termination resistor between the terminals (＋)(－) of communication output.
Note(
４
) In case of the high-voltage circuit, using instrument transformers (VT), and instrument for the
current transformer (CT) of secondary rated 5 A, please ground the secondary side.
Current sensor in the secondary of the current transformer, please connect the current sensor (CTF-5A)
of 5A rating.
