A) Before running the CT wires through conduit, use coloured tape to
mark each of the CTs and the free ends of its wires, marking each
with a different colour. You can run multiple CT wires through a
single conduit.
B ) Wire the IQ Gateway Metered for
power
•
Depending on the number of phases you will wire, use a one-, two-,
or three-pole (20 A maximum) circuit breaker for the supply wiring.
•
Make sure supply wiring is 2.5mm
2
copper rated at 75º C or better.
•
Locate the screw on the terminal block door, and loosen it with a
screwdriver to unlock the door and flip it open.
•
Connect Line 1 to L1, Line 2 to L2, Line 3 to L3, and Neutral to N, as
required.
•
Tighten all connections to 0.56 Nm
.
C ) Install the
production
CTs on phases as required:
•
Locate the arrow on the CT label.
•
To monitor production on Line 1
:
-
Connect the white wire to the “I1•” terminal and the blue wire to
the “I1” terminal.
-
Clamp the CT on active Line 1 of the solar production circuit with
the arrow pointing toward the load (away from the solar array).
•
To monitor production on Line 2
:
-
Connect the white wire to the “I2•” terminal and the blue wire to
the “I2” terminal.
-
Clamp the CT on active Line 2 of the solar production circuit with
the arrow pointing towards the load (away from the solar array).
•
To monitor production on Line 3
:
-
Connect the white wire to the “I3•” terminal and the blue wire to
the “I3” terminal.
-
Clamp the CT on active Line 3 of the solar production circuit with
the arrow pointing towards the load (away from the solar array).
•
Tighten all connections to 0.56 Nm.
The IQ Gateway Metered uses terminal blocks for power and metering connections. Wire these terminal blocks as described in the following.
You will need to i
nstall one split-core CT per monitored phase for production metering and one split-core CT per monitored phase for consumption metering.
Use
a protected route in conduit (raceway) for the CT wires to the IQ Gateway Metered. If you need to extend the leads (up to 148 meters), refer to the Enphase IQ Gateway
Metered Installation and Operation Manual at:
https://enphase.com/contact/support.

D ) Install the
consumption
CTs on phases as required:
•
Locate the arrow on the CT label.
•
Make sure that the AC mains wire(s) are de-energised until you
have secured the CT wires in the terminal blocks.
Note
: Only run active conductors of the same phase through each
CT. Each CT can monitor multiple active conductors.
•
To monitor consumption on Line 1
:
-
For the first CT, connect the white wire to “I1•” and the blue wire
to “I1”.
-
Clamp the CT on the main supply Line 1 (active). When the
consumption CT is on Line 1 (active) conductor, the arrow must
point towards the load (away from the grid).
•
To monitor consumption on Line 2
:
-
For the second CT, connect the white wire to “I2•” and the blue
wire to “I2”.
-
Clamp the CT on the main supply Line 2 (active). When the
consumption CT is on Line 2 (active) conductor, the arrow must
point towards the load (away from the grid).
•
To monitor consumption on Line 3
:
-
For the third CT, connect the white wire to “I3•” and the blue wire
to “I3”.
-
Clamp the CT on the main supply Line 3 (active). When the
consumption CT is on Line 3 (active) conductor, the arrow must
point towards the load (away from the grid).
•
Tighten all connections to 0.56 Nm.
NOTE:
Because of variance in switchboard design and main power
feed, there may not always be enough space to install CTs.
NOTE:
It is important to match CT and voltage sense phases. Be
sure to consistently identify all the AC lines at three points: the main
switchboard feed, the IQ Gateway, and the solar production circuit
breaker. Wire colours may not always consistently identify Lines 1, 2
and 3. If in doubt, use a multimeter to check.
DANGER!
Risk of electric shock. Always de-energise circuits
before wiring for power and CTs.
DANGER!
Risk of electrocution! Do not install CTs when current
is flowing in the sensed circuit. Always install CT wires in the
terminal blocks before energising the sensed circuit.

E ) Install DRM support and a central disconnect as required for Australia
.
The multi-phase IQ Gateway Metered gateway supports DRM (De-
mand Response Management). The IQ Gateway Metered (ENV-S-
WM-230 ) has a pre-installed 15kΩ resistor that provides DRED bypass
when DRED is not required.
NOTE
: In systems where a central disconnect (contactor) is installed,
you must configure the meters as described in Step 6 before device
discovery can complete.
NOTE:
Because of variance in switchboard design and main power
feed, there may not always be enough space to install CTs.
NOTE:
It is important to match CT and voltage sense phases. Be
sure to consistently identify all the AC lines at three points: the main
switchboard feed, the Envoy, and the solar production circuit breaker.
Wire colours may not always consistently identify Lines 1, 2 and 3. If in
doubt, use a multimeter to check.
DANGER!
Risk of electric shock. Always de-energise circuits
before wiring for power and CTs.
DANGER!

is flowing in the sensed circuit. Always install CT wires in the
terminal blocks before energising the sensed circuit.
