Precautions
The E-Mon D-Mon® Class 2000 meter is wired as a single-, dual- or
three-element unit that is used to monitor electric power to individual
loads after the utility meter. Installation must be performed by
qualified personnel and ONLY according to these instructions and
all applicable electrical codes. E-Mon and its representatives assume no
responsibility for damage or injury resulting from the improper
installation of this meter.
Check the rating and configuration on the meter label to ensure it is
suitable for the intended service. Meters listed for use on 120/208 volt
services cannot be used on 277/480 volt services, and vice versa.
Verify that the meter rating (amperage) is suitable for the intended load.
Compare the color of the arrows on the current sensor assembly to the
chart below to find the amperage of the current sensors.

Mount the meter in the desired location using the mounting flanges
located on the top and bottom of the meter enclosure. This E-Mon DMon meter model must be installed indoors, in an area that is free
from moisture and extreme temperatures. (An optional outdoor
enclosure is available; contact E-Mon for details.)
Assemble and install the current sensors around the conductors that are
to be monitored.
NOTE:
The modular jacks located on the meter board are to be used
only in conjunction with E-Mon peripherals. The jacks contain
neutral-accessible circuits.
Take the following precautions during installation:

CAUTION!
This device contains a NiMH battery that must be disposed of
properly. Replacing it with the wrong type of battery can cause
an explosion. Only qualified personnel should service this
equipment.
Reduce the risk of electrical shock or fire. Do not interconnect the
outputs of different Class 2 circuits.
Do not rely on the xcm.10S as a final safety device.
Make sure that the 24-VAC power wiring is connected to a
dedicated transformer. No other devices (including the outputs)
should be powered by the transformer connected to the xcm.10S.
Do not ground the transformer for this module on the secondary
side.
Make sure that the xcm.10S power cannot be switched off
accidentally. The xcm.10S requires continuous power for proper
operation.
Mounting
Mounting is comparable for all devices.
NOTE:
Be sure to read all precautions and warnings prior to
performing any electrical work.

Typical
Installation
Meter Terminal
Block Connections
Current Sensor Connections
STEP 1: Connect the black and white leads from the current sensor
assembly to the meter terminal block. The current sensor leads can be
extended up to 2000 feet using #14-22 AWG wire and do not have to be
twisted (consult your local electrical codes for proper sizing). When
extending the sensor leads, be sure to note what color lead on the
extension is connected to the black lead from the sensor, and what color
lead on the extension is connected to the white lead from the sensor.
There is no hazardous voltage across the current sensor wires and there
will be no damage if the sensor wires are shorted together. When
connecting current sensor leads to the meter terminal block be sure that
the white wire is connected to the "W" terminal, and the black wire is
connected to the "B" terminal for that phase.
NOTE:
Refer to the Wiring Diagrams, for further information on
current sensor connections.

Part # E-Mon Meters
Voltage Connections
STEP 1: Verify that the voltage supplied to the meter is from the same
source as the loads being monitored by the current sensors. Connect the
line voltage input wires to the meter terminal block. (See the various
installation diagrams.)
NOTE:
LINE VOLTAGE INPUTS MUST CORRESPOND TO THE
SAME CONDUCTOR BEING MONITORED BY THE
CURRENT SENSOR INPUTS. THE CONFIGURATION
SHOWN MUST BE FOLLOWED OR INACCURATE
READINGS WILL RESULT.
These wires are normally #14 AWG, but consult your local electrical
codes for proper sizing. Voltage input conductors require protection; it is
recommended that in-line fuses with a one-amp rating be installed to
protect all phases. Do not connect the voltage wires to the unit while they
are live. Push Lexan shield down over meter terminal block. Apply
voltage to meter only after installation is complete.
IMPORTANT:
The line voltage and current sensor inputs must correspond. If
the phasing between the voltage and the current sensors does
not correspond, inaccurate readings will result.
NOTE:
Refer to Chapter 4, Wiring Diagrams, for further details.
NOTE:
The line voltage input may be taken from wherever it is most
convenient (lugs, another breaker, another subpanel, etc.) as
long as it is the same power source as the items being
monitored. Line voltage cannot be pulled from a subpanel
powered from a different transformer than the item(s) being
monitored.

Interval Data
Recorder
The IDR (Interval Data Recorder) is an energy data collection device.
Installation must be performed by qualified personnel only and must be
in accordance with local and national electrical codes. Novar and E-Mon
are not responsible for damage or injury from improper installation.
The IDR is contained within a NEMA 12 enclosure and is designed for
INDOOR USE ONLY, where ambient temperatures are between +32 and
+120 degrees Fahrenheit. The IDR must be located in an area that is
central to the meters connected to it.
IMPORTANT:
The E-Mon D-Mon® meter that is connected to meter jack #1
on the IDR must be within 100 feet from the IDR, as it supplies
low-voltage power to operate the IDR.
All other meters can be located up to 500 feet from the IDR.

Part # E-Mon Meters
NOTE:
The IDR with modular jacks is designed to operate with E-Mon
D-Mon meters only. Terminal input models can support the
monitoring of third-party metering equipment; contact E-Mon
for further information.
The IDR must be installed in a location according to these guidelines to
ensure continued safe, trouble-free operation.
• Do not install near sensitive radio communications
equipment or receiving antenna systems.
• Do not install near high-energy electrical fields such as
those produced by welding equipment or by high-power
electrical motors.
• Always install in an area that is dry, away from any
potential liquid or chemical splash hazards. Never install
electrical equipment in an area where flammable chemicals
or vapors are present..
• The IDR enclosure's door must be kept closed once
installed. Exposing the internal circuits to dust, dirt, fumes
or high humidity can damage the IDR.
NOTE:
All internal circuits are isolated from the AC line.
NOTE:
IDRs with modular jacks can be powered from either the first
E-Mon D-Mon meter or by an external power supply (requires
120VAC). IDRs with removable screw-type connectors require
an external power supply (provided).
IDRs are supplied with an ID letter for each group of 8 inputs to make
them compatible with the E-Mon EnergyTM software. Available choices
are: A-B, C-D, E-F, G-H, I-J, K-L, M-N, O-P, Q-R, S-T, U-V, W-X and
Y-Z. No other combinations are available. When mixing 8-point and 16point IDRs together, it may be necessary to jump up a letter in the
system. As an example, if you have 8-point IDRs labeled “A”, “B” and
“C”, the 16-point IDR to choose would be the E-F unit.
The IDR is available in three configurations.

For each phase you will have two sets of current sensor wires. Join the
two white wires together in a splice (wire nuts, terminal block, etc.) and
bring one extension wire back to the white sensor input screw on the
terminal block in the meter. Do the same for the black wires and repeat
for each phase.
The extra set of current sensors is installed in a backwards direction. This
will subtract the usage of the breaker from the total usage seen by the
meter.
As with all situations where you are using more than one set of sensors
into one meter, all sets of sensors must be of the same amperage rating.
Phase correspondence must be maintained.

IMPORTANT:
Line voltage MUST be present at the A- & B-phase voltage
Monitoring two two-phase loads: terminals. (You cannot
bring power into A- & C-phase terminals only, or into B- & Cphase terminals only.)
Shorting link MUST be installed on C-phase current sensor terminals.
Parallel Current Sensor Rules
The E-Mon D-Mon® Class 2000 meter provides extreme flexibility by
allowing additional sets of current sensors to be used in parallel so
multiple locations can be monitored by one meter. This feature allows a
totalized display from two or more loads.
You may use parallel sensors to monitor specific breakers from one
panel, specific breakers from more than one panel, two or more complete
panels, etc.
You may also monitor three-phase loads and single-phase loads for a
totalized reading, provided they are from the same power source.
When paralleling current sensors, the following rules must be followed
for accurate readings.
RULE 1: Current sensors must be installed in complete sets of three.
This is necessary even when paralleling poly-phase with single-phase
loads.
RULE 2: All sensors used in parallel must be of the same amperage
rating (e.g., all 100 amp or all 400 amp). The rating will be determined
by the current rating (amperage) of the meter. A 200-amp meter, for
example, must use extra sets of 200-amp current sensors.
RULE 3: All locations being monitored must have the same power
source. A 480-volt meter, for example cannot monitor a 208- volt load,
nor can a meter monitor two 480-volt loads if they are from a different
originating power source or from different transformers.
RULE 4: The meter reading shown on the display must be multiplied by
the number of sets of current sensors installed.
Example: A meter using 2 sets of current sensors, with a display reading
of 20....2 x 20 = 40....the actual usage is 40.

Part # E-Mon Meters
NOTE:
Sets of current sensors consist of three sensors, one per phase.
The multiplier only applies when extra sets of sensors are
installed on one meter.
If you are only using one set of three sensors, this multiplier DOES NOT
apply.

1. In this instance, there are 2 breakers that need to be separated out
from the panel. They could be for a single tenant or common
area loads, etc.
2. You will notice, the two A phase load wires both run through the
A phase sensor, both B phase load wires through the B phase
sensor and the same for the C phase.
3. Make sure the load wires are going the same direction through
the sensor.
4. When ordering, size the meters amperage for the combined
amperage of the phase with the largest load.

After the installer has verified proper voltage, he or she must
determine if the meter is functional.
The step that is common to all the versions of Class 1000, 2000
and 4000 meters, is to disconnect all the current sensors wires
from the meter.
Before removing the sensor wires, be sure they are labeled
properly so they can be put back into the correct connection
point when the testing is finished.
The next step in the test varies somewhat for the different
versions of meter. On the next page you will find this next step
outlined for each meter type.
Class 2000 demand series
Once the sensor wires are disconnected, locate the 2-prong test jumper
above the terminal block and short across the two prongs with a
screwdriver or wire. As long as you are shorting the test jumper, the
check sensor light on the power supply circuit board and the ‘check
sensor’ light on the display will remain on. This indicates the meter is
functional.
QAT Checklist
Instantaneous kW test Class 2000 kWh and demand meters
Tools needed for this test: Screwdriver, multi-meter, calculator,

1. On the meter display circuit board on the inside of the board,
door, there is a row of small pushbuttons, below the large IC
display chip. The second button from the left is the CPU Reset
button. Pressing this button will show the amperage rating of the
meter on the display. Verify that the amperage rating of the
meter matches the amperage rating of the sensors connected to
the meter. Pressing this button will not reset the kWh or kW
readings.
2. Check for the installation error indicators: if either the ‘Check
Sensor’ light inside the meter or the ‘Check Sensor’ icon on the
display is visible, it is likely the meter is installed incorrectly.

left toggles on the instantaneous kW on the display. Press this
button. The instantaneous kW will show up on the screen, and
the reading will stabilize after a few seconds. Record the kW
reading.
4. Measure each phases current sensor voltage at the input screws,
(range is 0~2 volts), record the three voltages and then add them
together. This number is the Current sensor voltage total, and
will be used in subsequent steps in this test.
5. Perform the calculations shown below. They will result in the
Calculated instantaneous kW. Compare this figure to the
Measured instantaneous kW. If the two figures are within 2 kW,
the meter is installed correctly.
6. If the measured kW is approximately 1/3 low, check for an open
current sensor wire. If it is roughly 2/3 low check for a phasing
error.

Demand Meter
Q. How do I figure out if my meter is a kWh or a kWh/demand meter?
A. Your meter has the demand option if its model number ends in “D”.
Q. When providing line voltage to the E-Mon D-Mon® meter, can I tap
off the same breaker I am monitoring?
A. Yes, the voltage can be pulled off the same breaker being monitored.
The meter draws .025 amps, so the load from the meter will have
minimal affect on your readings. (Refer to proper fusing instructions.)
Q. Can the meter line voltage wires be run in the same conduit as the
current sensor leads?
A. Yes, there will be no effect on the meter if the sensor leads and the
meter line voltage wires are run in the same conduit.
EMONMETER- INS 2/16/2012

Part # E-Mon Meters
Q. What size wire do I use for the line voltage leads?
A. These wires are normally #14 AWG, but be sure to check your local
electrical codes for proper sizing.
Q. What size wire do I use to extend the current sensor leads?
A. These wires are normally 14-22 AWG wire, but consult your local
electrical codes for proper sizing. The sensor wires do not have to be
twisted, and can be extended up to 2000 feet.
Q. The load I need to monitor has parallel feeds. How do I install the
sensors for this application?
A. There are two ways to monitor parallel feeds. The first (and easiest)
way is to clamp the sensors around all feed wires for that phase; if the
core supplied with your meter is not large enough, contact your local
distributor and ask them to order a larger core size for your meter. The
second way is to clamp the sensor around one of the feed wires. When
you read the meter, the final reading must be multiplied by the number of
feed wires for each phase. For example, if you were using 6 conductors
in parallel per phase, you would clamp current sensors around one of the
conductors of each phase, take the reading from the display and multiply
it by six (6) for the parallel conductors. This result would be your total
kWh for the loads being monitored.
Q. I have two subpanels that I would like to monitor with one meter.
These subpanels are fed by different transformers in the building. Can I
parallel sensors and monitor both panels with one meter?
A. No. These panels cannot be monitored by one meter because they are
from different power sources. When you parallel current sensors, all
loads being monitored must be from the same voltage source.
Q. I have 5 breakers in one subpanel I would like to monitor with one
meter. Can this be done without having to parallel current sensors?
A. Yes. Simply run all the breaker wires through one set of current
sensors. Make sure all A-phase circuits are through the A-phase sensor,
and the same for phases B and C. The meter should be sized by the
highest amount of current being monitored by one sensor.
Q. I've gone through the troubleshooting guide and I still can't get my
meter to work. What should I do?
A. Contact Novar's technical department at ########## before
removing the meter. E-Mon's technical department will help you do
detailed troubleshooting of the meter installation in the field and assist
you in getting the meter up and running without you having to remove
and return the meter.
Q. How accurate are the E-Mon D-Mon meters?
A. E-Mon D-Mon meters are certified to ANSI C12.1 metering
standards. (+/-1% from 1-100% of the rated load.)

Q. What are the plugs inside the meter used for?
A. The plugs inside the meter are used to interface E-Mon D-Mon meters
with several available options, including pulse output, D/A output, highresolution displays and Automatic Meter Reading systems.
Q. How do I find the cost for kWh to bill my tenants?
A. Your local utility electric bill should list the cost per kWh; if it does
not, give your utility company a call and ask them the cost per kWh.
Q. I have an existing meter that I would like to interface with my energy
management system.
Can I field install the pulse output option into the E-Mon D-Mon meter?
Yes. Simply contact your local distributor and order the Pulser option.
Current Sensors
Following is a list of diagnostic messages that may appear on the meter
display.
DIAGNOSTIC MESSAGES SHOULD NOT BE ON
CONTINUOUSLY WHEN THE METER IS INSTALLED PROPERLY
AND IS IN WORKING ORDER.
Line Voltage Diagnostics
The diagnostics program detects line voltage faults by displaying one of
two messages: *PHASE [2] or *PHASE [3]
*PHASE [2]
Indicates that the 3-phase line voltage is not hooked up in the proper
phase sequence. This message should never be seen on the display
continuously. The meter will not display correct electrical data in this
condition. The phase sequence problem must be remedied in order for
the meter to work properly.
*PHASE [3]
Indicates that line voltage is missing on Phase B and/or Phase C. This
message will appear whenever the power on either Phase B or Phase C is
off. Screen 5 (Voltage per Phase) will also indicate a loss of line voltage.
Current Sensor Diagnostics
The load current must be at least 1% of the meter's rated load in order to
operate.
Current sensor diagnostics can detect:
1. Reversed current sensors
2. Incorrect phase correspondence
3. Unusually low power factor (0.642 or lower)
Two different sensor diagnostic messages are used: *SENSOR or *PHANGLE
EMONMETER- INS 2/16/2012
For the latest technical documentation, visit www.novar.com/manuals
46
Part # E-Mon Meters
*SENSOR (ABC)
Used to detect reverse phasing of a current sensor. This message should
never be seen in normal operation of a properly installed meter.
*PH-ANGLE (ABC)
Used to detect the swapping of current sensor phases. This message
could (in some rare cases) indicate an extremely low power factor
condition. This message may appear intermittently due to changes in line
conditions. It should never be on continuously.
NOTE:
If you have connected the current sensor to all three terminals
and the error message is still appearing, reverse the black and
white wires and repeat the previous steps until the correct
connection is found.
If the *SENSOR error message disappears you have found the correct
sensor connection; however, the current sensor was not installed properly
around the conductor, or the sensor wires were extended and not spliced
together correctly. Correct the sensor installation, reconnect the black
wire to the black terminal and the white wire to the white terminal on the
plug and reinstall the plug into the correct phase terminal for that current
sensor. The error message should disappear and the current sensor is now
installed properly.
If the *SENSOR message does not disappear at any time while trying all
3 inputs both ways, check the AC voltage output from the current sensor
between the black and white wires using an AC voltmeter. It will read
approximately zero volts indicating that the load current is very small (or
zero) or the current sensors are not secured properly (tight connection
between core halves or lead splices not secure).
Once the first current sensor is connected properly and the error message
disappears, repeat the previous procedure for the remaining two current
sensors. When all error messages have disappeared and all sensors are
installed correctly, the meter is operational.
The table below shows possible sensor connection errors that can be
detected and the error message displayed for each. In these conditions,
the current sensor wire pairs are tied to the correct inputs, but the
direction of at least one sensor is reversed as indicated. These are the
most common errors.
NOTE:
Underline denotes incorrect installation.
