Install CT / Pulse Wiring Modules into the Meter Base Unit
In most cases the CT / Pulse Wiring Modules are shipped pre-installed in the Meter Base
module. If new modules are being added or replaced, insert them as shown in Fig 8 below.

Install disconnect devices for sense and control voltages
Each Triacta GATEWAY device must be connected to all sense and control voltages through
properly rated (15 Amp) disconnects or breakers that disconnect all line wires so that they can
be powered down. Each disconnect or breaker must be located within easy reach of the
meter operator, and must be labeled to indicate which set of device inputs it supplies power
to.
One disconnect is required for each separate sense or control voltage input.
For installations with multiple Triacta GATEWAY devices, the same disconnects can be
used to power multiple meters. Each disconnect must be labeled for all devices it supplies
power to.
The disconnect device or devices must meet IEC 60947-1, IEC 60947-3 and/or comply
with the local electrical code.
Connect Control and Sense Voltage Wiring
For a single-phase panel, use a 3-wire, 14 AWG (1.63 mm2), 90°C (194°F) cable.
For a three-phase Wye panel, use a 4-wire, 14 AWG (1.63 mm2), 90°C (194°F) cable.
For a three-phase Delta service, use a 3-wire, 14 AWG (1.63 mm2), 90°C (194°F) cable.
Metallic, flexible armored cable (BX cable) is recommended for commercial
installations.
