Triacta GATEWAY
X2 (neutral) connections for each of the 12 CTs are listed in Table 3. The first colour of
each colour pair is connected to X1, and the second colour of each colour pair is
connected to X2 of each CT.
Typically, the CT/Pulse Wiring - 12Pair Cable Module would be used when all CTs are
located in the same distribution panel. The CT cable can be easily routed from the
Triacta GATEWAY to the distribution panel and the CTs can then be direct connected to
the CT cable inside the panel.
If CTs are located in different panels, or if there is a very long distance from the CTs to
the Triacta GATEWAY, it may be more desirable to route separate wire pairs from each
CT direct to the CT/Pulse Wiring - Screw Terminal module.
If more than one type of CT Measurement Module (ie 80ma, 100mA or 333mV) is
installed in the METER HEAD unit, ensure that all of the CTs on each CT / Pulse Wiring
Module are of the same type. Do not mix CTs of different types on the same CT/Pulse
wiring module. The position of each CT / Pulse Wiring Module in the Meter Base unit for
each type of CTs much also match the position of the corresponding CT Measurement
module in the METER HEAD unit.
CT Naming designations
Each CT is physically identified by the CT/Pulse wiring module slot and wire pair it is connected
to, and then logically identified (named) by a meter number and an element number (meter-
element).
The Triacta GATEWAY can support any combination of single element, two element and/or
three element meters in any order, up to a total of 12, 24, 36 or 48 elements depending on
the number of installed CT modules. The number of meters and the number of elements per
meter are determined by the metering configuration programmed into the meter.
The following table shows some sample CT naming configurations
