System Description
The Triacta GATEWAY is a modular, high density electrical meter and pulse collector system
for Measurement and Verification, Energy Management, and tenant billing applications. It is an
industrial grade, rapidly deployable platform with powerful communications options that will fit
any building use.
The Triacta GATEWAY system architecture consists of separate Triacta GATEWAY Meter
Base and Meter Head units. The Meter Base can be installed, and the electrical connections
terminated by electrical contractors, independently of the TRIACTA GATEWAY Meter Head.
The Triacta GATEWAY Meter Head may be installed at a later time by a technician with no
electrical accreditation.

Figure 3: Triacta GATEWAY Internal view
Figure 2 shows the internal view of the Triacta GATEWAY .
Triacta GATEWAY Meter Head
The Meter Head unit supports the following:
xOne to four measurement modules each supporting twelve inputs for 80mA CTs,
100mA CTs, 333mV CTs or pulse counters.
xLarge front panel 4X20 LCD display for manual meter reading and diagnostics
xOn-board Wifi for craft interface hotspot
xOn-board 10/100BaseT Ethernet
xTwo USB-2.0 ports for future use
xDual processor architecture for enhanced system capability and flexibility
Triacta GATEWAY Meter Base
The Triacta GATEWAY Meter Base supports connection points for the following:
xOne or two Voltage Reference Inputs
xOne optional Auxiliary Control Voltage Input
xOne to four self-shorting input modules supporting up to 12, 24, 36 or 48 wire pairs for
CT’s or pulse output devices.
xOptional future communication modules.
Triacta GATEWAY Voltage Module
The Voltage Module has two separate Sense Voltage inputs, an Auxiliary Control Voltage
input, and a control voltage jumper.

Figure 4: Voltage Module
The two sense voltage inputs (Vref1 and Vref2; A, B, C, N) provide the phase voltages
(VAC) used for metering one or two different service types. Ref 1 could be used for
120V/208V 3ph 4wire, and Ref. 2 could be used for a 277V/480V 3 ph 4 wire service. Either
voltage reference can be assigned to any configured meter point, regardless of which CT
module or which CT inputs the meter point uses.
When the control voltage jumper is installed it connects Phase A from the Vref1 sense
voltage input to the Triacta GATEWAY device control voltage circuitry. This eliminates the
requirement for a separate voltage connection to the Auxiliary Control Voltage Input.
Separate control and sense voltage wiring is required when using the Triacta GATEWAY
with a Triacta PT Module, or when the meter is expected to be ON at all times - even when
the sense voltage source is OFF. I.E. the sense voltage is from an emergency power panel
that is not always ON.
Both the control voltage and sense voltage inputs will accept panel voltages from 120VAC to
277VAC. If the reference voltage for the circuit/s to be metered is larger than 277VAC,
external potential transformers (PTs) are required.
Figures 16 and 17 show typical installations with Triacta PT modules. Figures 18 and 19
show typical implementations with discrete external transformers.
Typically, external metering PTs are sized to convert from the panel’s line-to-line or line-to-
neutral voltages (ie 600VAC or 347VAC) down to 120VAC. The appropriate PT ratio (ie 5:1
or 2.89:1) must be programmed into the Triacta GATEWAY configuration as per the “Triacta
GATEWAY Flex Configuration Tool Guide” to provide correct meter readings.
WARNING
WARNING The control Voltage Jumper must be removed if there is a separate
voltage source connected to the Auxiliary Control Voltage Input.

Triacta GATEWAY CT / Pulse Wiring Modules
Current transformers and pulse output devices are connected to the Triacta GATEWAY via
specially designed self-shorting CT / Pulse Wiring Modules as shown below. The self-shorting
mechanism on each CT / Pulse Wiring Module is activated when the Triacta GATEWAY Meter
Head unit is not installed.
Each CT / Pulse Wiring Module supports 12 inputs pairs, numbered P1 to P12. The Triacta
GATEWAY Meter Base unit supports up to 4 CT / Pulse Wiring Modules for a total of 48 input
pairs. The number of inputs available of each type depends on the number of measurement
modules and CT / Pulse Wiring Modules installed in the meter.
The two inputs on each input pair are designated as + or -. If the CT / Pulse Wiring Module is
for CT connections, the X1 / X2 leads from each CT must respectively connect to the + / -
inputs. If the CT / Pulse Wiring Module is for pulse output devices, the + / - wires for each pair
connect as per the specific pulse output device type.
Each input pair on the CT / Pulse Wiring Module also has a colour pair designation that
matches on of the colour pairs available in an optional Triacta GATEWAY CT/Pulse
Termination Cable. Table 3 describes the termination cable wire pair colour scheme for each
input pair on the CT / Pulse Wiring Module.
The CT / Pulse Wiring Module is also available with a CT/Pulse Termination cable pre-wired
and over mold protected to the module as per the colour pair table.
