Energy metering and monitoring are at the heart of energy management, understanding when
and where your energy is consumed is key to saving money.
The e2 wireless electricity monitor shows the amount of energy that a household is consuming
at the time the display is read. The display can also give the user a reading showing usage in
financial terms. You can walk around the home with your monitor device, switching appliances
on and off, to see the difference that each one makes. With a few small changes in your
consumption behaviour the e2 can help you reduce your energy costs.

IMPORTANT SAFETY INFORMATION
It is important that you take some simple precautions before using this product. Incorrect use
or poor safety practices can result in injury or fatality. Whenever possible, turn off the main
breaker, outside your home feeding power to your electric panel.
When installing the efergy monitor you should find that everything is straight-forward. However,
there are a number of important health and safety issues which you need to be aware of:
• CT sensor clip fits onto the internal live feed cable inside the electricity meter, which delivers
the live supply to your home.
• Please read and act upon the important information on the following pages. Remember the
device is not intrusive and does not require rewiring; no wires or cables need to be cut, removed
or modified to perform this installation.
• efergy energy monitoring systems are considered plug and play devices that meet all
regulatory requirements for installation in Canada and the United States.
• In some countries (i.e Australia) the live cable can only be accessed by qualified electricians.
Do not force or bend the cables at any point during installation. If you are worried or have any
concerns about the installation, please contact a qualified electrician immediately.
The user does not need to remove the sensor throughout the working life of the unit. Battery
changes are performed on the transmitter and on the display. There are no batteries to change
in the sensor.
Even with the main breaker in the off position, the connection lugs where the main wires
terminate at the main breaker may still be live with potentially lethal voltage. Stay clear of these
connections during the installation of the CT sensors (Page 9 Fig. 1 & 2).
The CT sensors themselves are insulated so do not be concerned if they slide down the main
wire to the breaker after being secured around the insulated wire. A plastic tie wrap (with 2” of
the tie not cut off) secured to the main wire under the desired location for the CT sensor may
be used to keep the CT sensor from sliding down the wire.
Millions of these systems have been installed world wide without incident but please follow safe
work practices as outlined during the installation.
• If you notice anything unusual about the electricity supply such as loose wires, exposed cabling,
burn marks, holes in the insulating materials or damage to the electric wires in the service panel
or where the CT sensors are to be attached, stop immediately and report the findings to your
supply company.

HARDWARE INSTALLATION
PRIOR TO INSTALLATION
Your e2 Pack contains the following elements:
CT sensor
Transmitter
2 x XL CT Sensors
1 x Transmitter
1 x e2 Wireless Energy Monitor
3 x AA Batteries
3 x AAA Batteries
You will need to attach the sensor to the live
feed cable which connects the meter to the
monitor. Any power you use in your home will
pass through this cable. The clip on sensor acts
as a CT sensor, and relays the amount of current
being drawn in the home to the transmitter.
From there it is sent wirelessly to the energy
monitor, which shows how much power is being
consumed.
Note - For a 120/240V panel (typical residential electric panel) power is measured using two CT
sensors. Set the reference point voltage during Monitor Setup to 120V or 130V for most rural
installations. For professional installation please consult the Technical Notes for Electrician
(see page 22).

Installation for Three Phase Panels
The e2 is installed by clipping the CT sensors around the feed wires of your electric panel. In
the case of a commercial or industrial three phase panel or service, you must use three CT
sensors to measure all three phases. Simply order an additional CT sensor from your dealer.
Identify the three power wires providing service to your electric panel. Open and place one CT
sensor around each of the three main feed wires.
Installing Transmitter for Three Phase
Plug the three CT sensor cables into the transmitter. Mount the transmitter on the wall next to
the electric panel. This will make it easier to replace the batteries. Readings for a three phase
system may not be accurate depending on connection and loading system.
You can upload your energy data from your e2
monitor onto your PC/Mac using elink software.

The efergy e2 is installed by clipping the CT sensors around the feed wires of your electric
panel. In Canada and the United States, the residential voltage is 120V for small appliances
and lighting and 240V for major appliances and equipment, such as central air conditioner,
electric water heater and oven.

HARDWARE INSTALLATION
HARDWARE INSTALLATION
MOUNTING INDIVIDUAL OR MULTIPLE CIRCUITS
Many buildings have separate apartments or efficiency apartments being served by the main
electric panel with only one electric utility meter. The e2 allows you to measure the usage for
these separate apartments, so you can determine how much electricity is being consumed by
the tenants. In Canada this is for information purposes only as efergy monitors are not sold or
intended to be used for revenue purposes.
If you wish to monitor various 120V and 240V circuits from the same panel, you can identify
which phase (or bus) these circuits are being fed from. Separate the wires for the circuits by
phase or bus.
Note - 1 A 120/240V residential panel has 2 busbars, each providing 120V power to the
loads/appliances. Some 120V circuit breakers are fed from one bus (bus A) and other circuits
are fed from the other bus (bus B).
Note - 2 Commercial and industrial electric panels may be served by two or three phases,
(normally designated as phases A, B & C). Some circuit breakers are one phase, others two
phases and some major equipment or loads may use three phases.
You can clip a CT sensor around the wire for each of the phases you wish to measure power.
This will measure the combined current flow in all of these wires (phases).
Locate Your Electrical Panel
You can normally find your main electrical panel inside your home on the other side of the wall
from your electric utility meter. You may also follow the conduit from your utility meter. In many
cases it is located in the garage, utility room, laundry room or hallway inside your home.
If you live in an apartment, it may be in the kitchen, a utility closet or hallway. Also in the case
of an apartment, your voltage may be 120/208V. Hardware installation follows the same steps
in this case as with an 120/240V panel.
Find the Main Feed Wires for Your Home
Remove the outside cover from your electrical panel and locate the main feed wires. Sometimes,
there will be an additional cover inside. These will be the wires that go to the main breaker in
your service panel, typically rated at 100 or 200A.
Mounting the Transmitter
Plug the CT sensor cables into the transmitter. Then mount the transmitter on the wall next to or
above the electric panel. This will make it easier to replace the batteries (although the batteries
will last for a long time). If the panel is in a finished area, you may mount the transmitter inside
the electrical panel. This may reduce transmission distance.
You can also place a CT sensor around a number of wires on the same phase to measure the
total amount of power traveling through the wires on that phase.

MONITOR INSTALLATION CONSIDERATIONS
INSTALLING THE CT SENSORS
The display for your efergy monitor may be wall mounted at a convenient location. It may
also be taken in hand throughout your home to determine how much different electrical loads
consume. All efergy monitors update every ten seconds so you can apply any new load and
watch for the change in the reading on your display.
IMPORTANT - Always make safety your first priority, see Important Safety Information (page
3). Do not touch any metallic connections during the installation of the CT sensors. Do not
carry out this installation if under the influence of alcohol or drugs.
1. Pull the clasp to open the CT sensor
1. O pen and place one
CT sensor around each
mains cable
Do not touch below this level
2. Plug the C T sensors’
jacks into the transmitter
2. Place the CT sensor around the cable.
Remove a standard ½” knock out from the panel. Feed the CT sensors’ leads from inside the
panel out through the raw knock out hole, leaving the protective rubber tip on the jacks in
place. Open and place one CT sensor, around each main feed wire (Fig. 1). The bushing is
then pushed on to the CT wires outside the panel and then snapped into the hole. Replace the
panel cover(s) when finished installing the CT sensors.
Please note the metal lugs where the main service wires attach to the main breaker. Keep your
fingers well away from these lugs unless you are able to turn off the inbound power from your
utility source outside. Wiring configurations and types of main panels will vary greatly.
If in doubt, contact an electrician or other qualified person to assist you with the installation of
the CT sensors.
You should find up to four feed wires entering your 120/240V or 120/208V main electrical
panel: two black wires, one white wire and one green wire. (There may not always be a green
or bare ground wire) The two black wires (or sometimes one black and one red) are the live
wires feeding the panel. These are the wires used to measure the power being used in your
home or business.
The CT sensors will be installed on the black wires or the black and red wires. Two CT sensors
are required for monitoring a 120/240V residential panel or 240V appliances or equipment. One
CT sensor is required for monitoring a 120V panel or 120V circuits or appliances.
