the Y-Phase current cable through the meter CT hole in
such a way that current flows in from "Y-Phase Source"
and passes out through "Y- Phase Load". NOTE: The
current carrying capacity of the whole current meter is
limited by the maximum cable size which can be passed
through the CT hole, which is 4sq.mm.
7. For CT operated meter, connect the two wires from the B-
phase CT to terminals marked M3 & L3 such that S1 from
CT goes to M3 on the unit. For whole current meter, pass
the B-Phase current cable through the meter CT hole in
such a way that current flows in from "B-Phase Source"
and passes out through "B-Phase Load". NOTE: The
current carrying capacity of the whole current meter is
limited by the maximum cable size which can be passed
through the CT hole, which is 4sq.mm.
8. For meters supplied with Dual Source facility, make the
connections in such a way that there is no voltage
between DP and DN terminals when the power is drawn
from the EB source, and a clean 150-270 VAC appears
