Gateway GXXXX
System Description
The GATEWAY™ is a modular, high density electrical meter and pulse collector
system for Measurement and Verification, Energy Management, and tenant billing
applications. The hot-swappable GATEWAY Head, coupled with the GATEWAY
Enclosure, comprise a GATEWAY GXXXX System: an industrial grade, rapidly
deployed unit with powerful communications options that will fit any building use case.
The GATEWAY™ architecture consists of a separate Gateway base Enclosure and
HEAD unit. The Enclosure can be installed, and the electrical connections terminated
by electrical contractors, independently of the GATEWAY Head. The Gateway HEAD
may be installed at a later time by a technician with no electrical accreditation.

Gateway GXXXX
Figure 2: Gateway internal view
Figure 2 shows the internal view of the Gateway.
GATEWAY™ Meter Brick
The meter brick supports the following:
•
One to four sensor modules each supporting twelve inputs for 80mA CTs, 100mA
CTs, 333mV CTs or pulse counters.
•
Large front panel 4X20 LCD display for manual meter reading and diagnostics
•
On-board Wifi for craft interface hotspot and future IP networking
•
On-board 10/100BaseT Ethernet
•
Two USB-2.0 ports for future use
•
Dual processor architecture for MID compliance (Europe) and enhanced system
capability and flexibility
•
Secure web browser interfaces for programming, meter reading and diagnostics.
GATEWAY™ Enclosure
This enclosure supports termination connection points for the following:
•
One or two Voltage Reference Inputs
•
One optional Auxiliary Control Voltage Input
•
One to four self-shorting input modules supporting up to 12, 24, 36 or 48 wire pairs for
CT’s or pulse output devices.
•
Optional future communication modules.
Gateway™ Voltage Module
The GXXXX Voltage Module has two separate Sense Voltage inputs, an optional Auxiliary
Control Voltage input, and a control voltage jumper.

Gateway GXXXX
Figure 2: 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 Gateway device control voltage circuitry. This eliminates the requirement
for a separate voltage connection to the Auxiliary Control Voltage Input.
Warning: The control Voltage Jumper must be removed if there is a separate voltage source
connected to the Auxiliary Control Voltage Input.
Separate control and sense voltage wiring is required when using the Gateway GXXXX 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 voltages from 90VAC to
300VAC. If the reference voltage for the circuit/s to be metered is larger than 300VAC,
external potential transformers (PTs) are required.
Fig xxx shows a typical implementation with discrete external transformers. Fig yyy shows a
typical installation with a Triacta PT module.
Typically, external metering PTs are sized to convert from the panel’s line-to-line or line-toneutral voltages (ie 600VAC or 347VAC) down to 120VAC. The appropriate PT ratio (ie 5:1
or 2.89:1) must be programmed into the Gateway GXXXX configuration to provide correct
meter readings.

Gateway GXXXX
Gateway CT and Pulse Input Termination Modules
Current transformers and pulse output devices are connected to the Gateway GXXXX via
specially designed self-shorting termination modules as shown below. The self-shorting
mechanism on each termination module is activated when the Gateway Head unit is not
installed.
Each wiring module supports 12 inputs pairs, numbered P1 to P12. The Gateway base unit
supports up to 4 termination modules for a total of 48 inputs. The number of inputs available
of each type depends on the number of measurement modules and wiring modules installed
in the meter.
The two inputs on each input pair are designated as + or -. If the termination module is for
CT connections, the X1 / X2 leads from each CT must respectively connect to the + / inputs. If the termination module is for pulse output devices, the the + / - wires for each pair
connect as per the specific pulse output device type.
Each input pair on the termination module also has a color pair designation that matches on
of the color pairs available in an optional Gateway CT/Pulse Termination Cable. Table 2
describes the termination cable wire pair color scheme for each input pair on the termination
module.
The Termination module is also available with a CT/Pulse Termination cable pre-wired and
over mold protected to the module as per the color pair table.

Complete the installation record provided with each Gateway system to record which
CTs or pulse devices are connected to each input pair on each termination module.
See Figure X for an example.
Connect Pulse Inputs
Connect each external pulse output device to be monitored (gas, water, BTU meter, …) to a
separate pulse input pair (+/-) on any of the termination modules designated as a pulse input
module.
Each pulse input is compatible with both dry (reed) and solid-state Form A contacts.
When the pulsing device provides solid-state form A outputs, the negative terminal from the source
device must be connected to the negative (-) terminal of the Gateway GXXXX pulse in terminal
block.
When the pulsing device provides dry contact (reed) pulse outputs the pulse input wire pairs are not
polarity-sensitive.
The maximum input pulse rate is 10 Hz (maximum), and the minimum input pulse width is 20 ms.
The recommended wiring for pulse input pairs is 22 AWG shielded twisted pair wires for distances up to
300 ft (100 m). Use larger gauge wire for larger distances up to 600 ft (200 m).

Gateway GUIDE
For each external pulse output device, document the pulse input module and the wire pair it is connected
to, and the units per pulse output of the device.
Insert the Head unit
In most cases the Gateway meter will be shipped with the Head unit pre-assembled into a base unit.
Alternately, the base unit can be pre-installed early in the construction phase (ie as the electrical
panels are being built) and the Head unit can be inserted later when the installation is ready to be
commissioned.
Before installing the Head unit be sure to turn off all the power feed/s to the Gateway Base unit and
to all panel/s where the CTs are installed. Always use a properly rated voltage sensing device to
confirm power is off.
Slide the Head unit down from above so that each of the alignment tabs on the Head unit go behind
the alignment pins on the Base unit as shown in the diagram below.
Push down firmly on the Head unit to fully insert the Head unit edge connectors into the Voltage,
Termination and Communication Modules installed in the Base unit.

Appendix 1: Current Transformers Overview
Current transformers (CTs) measure the current flowing through a wire. They are installed
around each wire for each circuit to be monitored and connected to the Gateway Gxxxx
via a Gateway termination module.
CT Types
Current transformers are classified by their secondary output (80 mA, 100 mA, 5A, or
333 mVolt) and by their physical appearance (solid core, split core, or rope).
Table 2 lists the Gateway GXXXX CT Sensor Modules and the types of CT that can be
used with each module. The table also indicates the maximum distance and corresponding
wire gauge for connecting each type of CT to the Gateway GXXXX.
For Gateway GXXXX release 1.0, rope (Rogowski Coil) CTs must have an external
integrator. Future releases will provide an internal integrator function which will allow the
rope CTs to be directly connected to the Gateway GXXXX.

As shown in table 2, 5 Amp secondary CTs can work with the Gateway GXXXX by using
Triacta 5A:100mA or 5A:80mA CT convertors (figure 13). One convertor is required for
each 5A secondary CT.

Gateway GUIDE
CT Orientation
When installing each CT, ensure that the orientation of the CT matches the direction
of the energy flow as indicated on each CT.
The direction of energy flow is identified by either;
1)
2)
3)
a label - “This side towards source”,
an arrow - the arrow points away from the source, or
a stamp or label indicating which side is H1 - the H1 side faces towards
the source.
If the orientation is backward, the meter readings will be incorrect.
Figure 14: Triacta 100 or 80 mA current transformer
CT Wiring polarity
Each CT has two output wires or posts. One output is X1 (positive) and the other output is
X2 (neutral). The X1 output is normally labeled directly on the CT. It may be explicitly
identified as X1, or it may be identified with a dot. If there is no X1 marking, refer to the CT
manufacturer’s documentation to determine the proper polarity.
The X1/X2 outputs from each CT for each circuit must be connected to the X1/X2 inputs of
each corresponding CT input connection on the appropriate Gateway GXXXX CT input
module.
When installing CTs in a panel, ensure that all CT wiring is labeled with the proper
X1/X2 designations, or that it follows a standard X1/X2 color pair mapping. If the
CT wiring polarity is incorrect, the meter readings will be incorrect.
CT Phasing
Depending on the number of voltage phases and the number of wires connected to each
circuit being measured, a minimum of one, two or three CTs are required for each meter
point to correctly measure energy usage by the circuit.

Ensure that the correct number of CTs are properly installed on each circuit, and that the
X1/X2 wire pair connected to each CT is labeled with the correct circuit name and phase.
Ensure that the phase of the wire that each CT is installed on matches the sense voltage
input phase connections as shown in the relevant voltage connections drawings.
Note that standard circuit wire phase colors and/or breaker positions do not always
match from one panel or circuit breaker to another. It is recommended that the phasing
is verified from the circuit to the sense voltage source with a voltmeter and not just by
visual inspection.
If the CT phases do not match the sense voltage phases, the meter readings will be
incorrect.
CT Shorting and Termination
The X1 and X2 outputs for all 5A, 100mA or 80mA CTs MUST always be either shorted or
terminated toameterwhen the circuits that they are installed on are energized. Failure to
terminate or short a CT on an energized circuit can cause dangerous voltages on the open
CT leads that can result in a fire hazard and/or catastrophic damage to the CT.
The CT termination modules have built-in shorting that is activated whenever the
Gateway Head unit is not installed.
5A CTs should have their own shorting/shunt connector that allows each set of 5A CTs to
be independently shorted at the 5A secondary (see Figure 13 on page 22). For safe
access, the 5A converters and shorting should be installed in a dedicated metering
compartment located in a main distribution panel, or in a separate metal enclosure.
CT Wiring Modules
Two types of CT wiring modules are available for the Gateway GXXXX.
One wiring module has built-in termination blocks for direct connections of up to 12 CT
wire pairs. When connecting CTs to a CT Wiring - Termination module, each CT is
connected to one of the connection points on the termination block, labeled from P-1 to
P-12. The X1 and X2 inputs for each CT are labeled +/- for each connection point.
A second wiring module provides a XXX foot long cable with 12 uniquely color coded
wire pairs. Each CT is connected to one of the twisted-pair wire color pairs in the 25-pair
CT connection cable. The color codes for the X1 (positive) and X2 (neutral) connections
for each of the 12 CTs are listed in Table XXX. The first color of each color pair is
connected to X1, and the second color of each color pair is connected to X2 of each CT.
Typically, the CT Wiring - CT cable module would be used when all CTs are located in
the same distribution panel. The CT cable can be easily routed from the Gateway
34 © 2018 Triacta Power Solutions LP. All Rights Reserved
34
Gateway GUIDE
GXXXX 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 Gateway GXXXX, it may be more desirable to route separate CT wiring from each
circuit direct to the CT Wiring - Termination module.
If more than one type of CT Sensor Module (ie 80ma, 100mA or 333mV) is installed in
the HEAD unit, ensure that all of the CTs on each wiring module are of the same type.
Do not mix CTs of different types on the same CT wiring module. The position of each
wiring module in the base unit for each type of CTs much also match the position of the
corresponding CT Sensor module in the HEAD unit.
CT Naming designations
Each CT is physically identified by the CT wiring module slot and wire pair it is connected to
and then logically identified (named) by a meter number and an element number (meterelement).
The Gateway GXXXX can support any combination of single element, two element and
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.
