Prepare Installation
Determine Panel Type
Select Mounting Location for the Unit
Energy Data Gateway parts are defined in Fig 1. Select a
mounting location (side, top, or bottom of panel) for the
unit. Make sure mounting location leaves 3” clearance
above top cap for sliding Cover Plate and Top Screw. And
leave 2” clearance on bottom for Ethernet port and Power
Plug. Fig 2
Side of panel (for surface-mount panels)
1. Look for an existing 1” knockout in the panel or create
a new 1” knockout, using the knockout punch or a
power drill with a hole cutter.
2. Detach front cap from Energy Data Gateway body by
removing top screw.
3. Mounting bracket is supposed to be attached on
Energy Data Gateway body, place Energy Data
Gateway body over panel knockout and insert 1”
chase nipple into the knockout hole. This will protect
cables from sharp edges. Fasten locknut onto nipple,
securing Energy Data Gateway body onto the panel.

IMPORTANT
For all installations: You should not insert the voltage tap cable leads in tandem with an
existing branch circuit wire (“double lugging”), unless the breaker is identified for the
termination of two conductors per NEC 110-14(a).
Select Breakers For Voltage Tap
Install one voltage tap on each phase of the panel. The voltage tap can be performed
without shutting off any breakers if there is at least 1 spare breaker per phase. If no spare
breakers are present, but there are empty slots in the panel, spare breakers can be
inserted and used for the voltage tap as well.
NOTE: If you do not have one spare breaker on each voltage phase, you will need to briefly shut down the voltage
tap breakers to complete this step. Please confirm with building operators that this will not interfere with
operations or safety protocols.
1. Open panel and locate 1 spare breaker on each phase. Choose breakers as close to
each other as possible to keep the wires organized.
NOTE: If the panel does not have any spare breakers, shut off 1 breaker on each phase.
2. Label selected breakers ‘Switch for VS sub-metering’.
NOTE: Energy Data Gateway voltage taps have a built-in in-line fuse; does not require additional fuse protection.

Install and Connect CTs
Select Appropriate CTs
NOTE: Select the appropriate CTs for breaker ampacity. Larger amperage circuits may require the use of Large CTs
in combination with high current CT interface modules.
Verdigris offers the following CT sizes
(up to 21 per chain; 42 total per system):
• Verdigris Smart CT
60A
• Large CTs
200 A Hinged CT
4” 500 A Coil CT
7” 500 A Coil CT
Larger sizes available by custom order
Verify CT Install Location
Make sure there is a vertical and horizontal clearance of 1” around each cable at the point
of desired CT installation as shown in Fig 12. If clearance between adjacent cables is
0.5"-1.0", stagger CT installation as shown in Fig 13. If a 0.5" clearance does not exist, this
product may not be suitable for your installation. Please contact your local building
inspector for final determination.
Install CTs
1. Open the CT loop by pulling plastic tab up and out towards ‘PULL’ arrow direction.
Fig 14.
2. Starting from the top of the panel, position CT window around circuit breaker wire
making sure CT cable is facing away from the breaker.
3. Close CT loop by snapping CT ends together. It may be easier to close CT by pulling
plastic tab with one hand while applying pressure on CT top & bottom surfaces with the
other hand. Fig 15.
IMPORTANT
The ‘LOAD’ arrow should
point in the direction of
current flow (i.e. left
breaker CT ‘LOAD’ arrow
should point to the left,
and vice versa for the right
breaker CTs).
Make sure individual CTs
are attached to desired
circuit wires before daisy
chaining CTs together
(see Connect Multiple CTs
section on p.13).
CTs must be securely
closed for accurate data
collection.
4. Repeat steps 1-3 with more CTs until all desired circuit wires have a CT attached.
Spare breakers with no wires installed can be skipped.
NOTE: A maximum of 21 CTs may be installed in continuity. This means up to 21 CTs (or up to 7 high current
CT interface modules) may be mounted on either side of a panel, which covers a standard 42 circuit panel.

Large CTs & Verdigris High Current CT Interface Module
Large CTs can be installed around a conductor. There are
two types of CTs: hinged CTs and coil CTs. Fig 16.
1. Open the large CT:
• Hinged CTs: Unlatch the CT at the opposite end of the
hinge by lightly pulling up and lifting the latch.
• Coils: Squeeze the ends to release the latch and open
the coil.
2. Wrap the opening of the CT around the large circuit wire.
3. Securely close the CT.
• Hinged CTs: Click the latch closed. Double check for the
correct CT orientation via the load arrow or CT label.
• Coils: Squeeze the ends to release the latch and insert
end of the coil. Double check for correct CT
orientation via the load arrow.
4. Insert the 2 wire leads from the large CT into the
Verdigris high current CT interface module terminal
block. Match the colors of the wire leads with the black
and white ports in the high current CT interface module
(black on the right, white wire on the left). Fig 17.
5. Orient the high current CT interface module terminal
blocks on each side of the panel as shown in Fig 18.
6. Attach large CTs to the high current CT interface
module in order of 1, 2, 3 as shown in Fig 18.
7. Using the magnet on the bottom of the high current CT
interface module, mount it to any grounded metal
surface in the panel, such as the side or back walls.
NOTE: CT chains and large CTs/high current CT interface modules can be
used interchangeably in terms of order. For example, on the left side of a
panel, the installation could begin with 15 CTs, followed by 3 large CTs with
a high current CT interface module, followed by another 3 CTs.
IMPORTANT
Large CTs must be oriented properly, otherwise inaccurate
data may result. Large CTs should be mounted such that
the load arrow points in the direction of the load on the
circuit. In most cases, the arrow points away from the
breaker.
For hinged CTs, if it is difficult to see the load arrow, the CT
label should be mounted with the label towards the
source.

Check the CTs
• Check each CT to ensure that they are closed properly.
• Check the load arrow on the CTs points in the direction of
the load.
• Check all High Current CT Interface Modules to ensure
Large CT leads are properly inserted into the terminal
blocks, and all large CTs are snapped closed.
• Check all data cable connections to ensure they are
properly seated.
Chain Check
The Verdigris Meter includes data cables that carry power
and digital signaling to and from its sensors. As there are a
number of connections per system, it’s possible some
connections are not made properly. Built into the meter is a
chain validation procedure to ensure a proper electrical
connection is made.
On power-up, the system will run a chain check diagnostic
procedure:
In the event the chain light is red, the procedure described
here can help identify and repair any issues.
Terms And Definitions
Chain 1 & Chain 2:
The cabling from the Energy Data Gateway to each of the
sensors. There are two loops of cable here, marked with
Chain 1 & Chain 2.
Sensor (Smart CT and Interface Module) LED Indicators:
•Slow Blink: a blink pattern on the Smart CT or High
Current CT Interface Module LED. This LED is white. This
blink pattern is 1 second on, 1 second off.
•Fast blink: a blink pattern on the Smart CT or High
Current CT Interface Module LED. This LED is white. This
blink pattern flashes 5 times per second.
•Solid: The light on the Smart CT or Interface Module will

•Off: The light on the Smart CT or Interface Module will be off.
Diagnosing Chain Errors
After current sensors and the Energy Data Gateway are
installed, the system can be tested for proper connectivity
through the sensor cable. The Energy Data Gateway during
this time can be powered either through a supplied battery
pack from Verdigris or from the panel powering the device,
through the voltage headers. Avoid powering the device
from both sources at the same time.
To perform the chain check procedure, the panel cover
should be open. The lights on the back of the Verdigris
Smart CTs or the Interface Modules will indicate more
information about where the error is occurring. While the
system provides as much information as it can on the
source of the disconnect, some work may be needed to
locate a loose connector or failed component.
System Chain Check
IMPORTANT
Double-check the installed CTs, as the physical
movement of items inside of the panel from CT
installation and data cable connection can cause CTs to
become loose.

Steps
1. Ensure the system is powered and you can visually see
the LEDs on the sensors. We recommend using the
battery pack, as it avoids needing to have the panel
powered during the check.
2. Run chain check by pressing the “Setup” button on the
bottom of the device. After pressing the button, the CT
and voltage lights will turn White to indicate the test is
in progress.
3. In about 3-5 seconds, the sensors lights will blink
showing the test has been run.
a. When in a correct operation, these lights will turn on
solid for 2 seconds, fast blink for 2 seconds, then
finally turn off.
b. In a failed condition, the sensor lights will either all
stay “Solid”, all “Slow Blink”, or do a mix of the two.
The instructions that follow will refer to the sensor chain
with the lights that remain on.
A. All Solid Lights:
If all the lights are “Solid”, there is a cabling issue at the start
of the chain. This affects either the first sensor on the chain,
the extension cable from the Energy Data Gateway (EDG,
male plug from the Gateway), or the pigtail cable coming
from the EDG.
•Check that cables are fully seated coming from the plug
of the EDG to the first sensor. If any cables are found to
be loose or not fully seated, fully insert the cable and
press the “Setup” button to re-run chain check. If the CT
light is green, the chain has been repaired.
•Bypass the first sensor on the chain by unplugging the
extension (plug) from the first sensor and attach it to the
second sensor. Re-run chain check. If this works, Find
another sensor to replace the first sensor on the chain
and connect the chain again as it was before. Re-run
chain check again to verify and close the panel if the CT
light turns green.
•Take a spare 3-meter extension cable and replace the
extension from the EDG with the plug side going into the
first sensor. You do not have to run the spare cable through
the conduit yet. Re-run chain check after this cable is
replaced. If the chain light shows green, the extension
cable going to the first sensor needs to be replaced.
• Unplug both cables from the output and input on the
EDG for this chain and loop the plug cable back into the
socket of the EDG directly. Re-run chain check to verify
the Chain light turns green. If the Chain light is still red,
the EDG should be replaced.
B. All Slow-Blinking Lights:
If all the lights show a “Slow Blink”, there is a cabling issue
at the end of the chain at the Energy Data Gateway (EDG)
(socket connector from the EDG to the plug of the last sensor).
This affects either the last sensor on the chain, the extension
cable to the Energy Data Gateway (EDG, female socket from
the Gateway), or the pigtail cable coming from the EDG.

•Check that cables are fully seated coming from the socket
of the EDG to the last sensor. If any cables are found to be
loose or not fully seated, fully insert the cable and press
the “Setup” button to re-run chain check. If the CT light is
green, the chain has been repaired.
•Bypass the last sensor on the chain by unplugging the
extension (socket) from the last sensor and attach it to the
second to last sensor. Re-run chain check. If this works,
Find another sensor to replace the last sensor on the
chain and connect the chain again as it was before. Re-
run chain check again to verify and close the panel if the
CT light turns green.
•Take a spare extension cable of a suitable size and
replace the extension to the EDG with the plug side
going into the EDG. You do not have to run the spare
cable through the conduit yet. Re-run chain check after
this cable is replaced. If the chain light shows green, the
extension cable going from the last sensor into the EDG
needs to be replaced.
• Unplug both cables from the output and input on the
EDG for this chain and loop the plug cable back into the
socket of the EDG directly. Re-run chain check to verify
the Chain light turns green. If the Chain light is still red,
the EDG should be replaced.
C. Solid Light And Slow-Blinking Lights:
If all the sensor lights show a mix of solid and slow blinking
lights, there is a cabling issue at the transition point where
the lights go from solid to blinking on the chain. This issue
affects the sensor before or after the transition in light code.
•Check that cables are fully seated at the point where the
light code transitions.
•Bypass the sensor immediately before the light code
transition and re-run chain check. You can bypass the
sensor by detaching it from the chain completely and
connecting the sensor before and after.
•Bypass the sensor immediately after the light code
transition and re-run chain check.
Once the offending sensor has been identified, replace the
sensor and re-run chain check.
