WARNING
Failure to attach the protective earth ground wire securely to the
enclosure creates a potential shock hazard. Do not operate the Class
2000 meter without a protective earth ground connection securely
installed.
3. Wire Entry.
a. Two openings exist on the unit enclosure, one for 1/2” conduit and one for 3/
4” conduit. The 3/4” conduit opening located on the bottom of the enclosure
is used to bring in MAINS Power (voltage lines to power meter) and current
sensor wiring. The 1/2” conduit opening located on the top of the enclosure
is used to interface low voltage signals, such as the IDR interface and isolated pulse output. (Outdoor enclosures equipped with one 3/4” conduit
opening on bottom of enclosure only.)
b. Route the appropriate cabling to and through the respective enclosure open-
ing. The conduit and fittings interfacing the enclosure entrances must be UL
listed and properly sized to the enclosure port diameter, The interfacing fitting must use a gasket seal ring to interface between the conduit fitting and
the enclosure entry point. After installing the conduit fitting and conduit, verify
that the conduit fittings are aligned properly to their respective enclosure
entrance ports and tightened securely to prevent moisture entry. VERIFY
that each conduit slip nut is securely tightened to its respective conduit fitting.
c. Outdoor applications require the use of the optional 4X enclosure. The same
principles outlined for indoor meter installations as defined in the aforementioned paragraph carry over and apply to outdoor installations with one
exception. The exception is that the conduit and fittings for outdoor installations require an outdoor material rating and approval for 4X applications.
4. Unit MAINS Wiring (Voltage Wiring Connections)
a. Remove the shield located over the phase A,B and C screw terminals on the
main power board. This shield can be removed by pulling back on the latch
on the right side of the shield and lifting up on the front. Wire each connection to the terminal block with stranded wire 14-12 AWG, rated at 600 VAC.
b. Strip back all wire insulation to expose between 1/4” and 3/8” of the copper
conductors. Gently twist each wire to prevent fraying. Insert the conductors
into their respective terminal block position and tighten down the terminal
block screw to securely fasten the conductor. The terminal block is clearly
labeled PHASE A, PHASE B, PHASE C and NEUTRAL.
c. Connect the NEUTRAL wire to the appropriate terminal block position.
NOTE: For Delta MAINS input wiring, DO NOT connect the NEUTRAL wire.
Remove the terminal block screw for this position.

d. Connect the AC mains power wires (Phase A, Phase B and Phase C) to their
respective positions as labeled on terminal block.Tighten the screws to 7 inlb of torque.
e. After all conductors are connected to their respective terminal block positions
and tightened down, verify that each terminal block screw is securely fastened by gently tugging on each conductor. Verify no conductor wires are
frayed or are shorting to adjacent terminal block positions.
5. External Switch Mechanism/In-Line Fuse Installation
a. To ensure a safe installation, the Class 2000 meter requires an external
switch mechanism, such as a circuit breaker, be installed on the Class 2000
MAINS input wiring. The switch mechanism must be installed in close proximity to the meter and easily reachable for the operator. This device must
also be marked as the disconnecting device for the Class 2000 meter.
b. Install 1/10 Amp Slow Activation in line fuses with the suitable voltage rating
for each conductor phase at the MAINS input to the meter. The fuses must
be labeled to indicate voltage and current rating as well as element characteristics. The fuse element must be slow activating type.
6. Once the MAINS wiring is complete, replace the clear Lexan protective shield
over terminal block TB1 and close the enclosure front panel. Secure the enclosure cover using the locking mechanism. Activate the external circuit breaker or
equivalent switch to apply AC MAINS power to the unit.
7. The Class 2000 meter display should turn on and indicate total kWh accumulation reading.
NOTE: On demand meters (meters ordered with "-D-") the unit display, clock
and other critical configuration parameters will be set once the unit
installation and wiring is complete.
8. Using an AC Voltmeter, verify the input voltage readings are within the limits
specified below.

CLASS 2000 METER
4.3 Current Sensor Installation & Wiring
Once the AC voltages have been confirmed to be within acceptable limits, you are
ready to install the current sensors. The MAIN power board contains three header
connectors located at the bottom right of the board. The connectors are labeled A, B,
and C along with conductor color indication. This format must be followed in order for
the meter to function correctly.
The Class 2000 meter will be used with one of two basic types of current sensors:
a. Split-Core Current Sensor: This sensor opens so that it can be attached
around the circuit conductor being monitored without interrupting power.
Unless otherwise specified, all Class 2000 meters are supplied with this
sensor type.
b. Solid-Core Current Sensor: This sensor does not open and requires the
monitored conductor be removed from the circuit to install the current sensor.
This type is only supplied when specified at time of order.
NOTE: The unit serial label specifies if the unit is set up for split or solid core
current sensors. See ordering information for details.
Both types of current sensors output a 0-2 VAC signal proportional to the current being
measured.
The current sensors must be matched with the voltage phases. The A phase sensor
must be monitoring the same phase as the A phase voltage. B & C phase sensors
must also monitor the same phase as their respective voltage inputs.

LOAD
SOURCE
4.3.1 Installing the Split-Core Current Sensor Assembly
Each phase being monitored will require one two-piece current sensor assembly.
Therefore, a three-phase meter will require three (3) assemblies. Open the two-piece
current sensor assembly by releasing the nylon clamp using a flat head screwdriver.
Fig. 4. Split-Core Current Sensor Assembly.
1. Reassemble the current sensor assembly around the conductor(s) to be moni-
tored. Ensure the current sensor halves marked “Load” are both facing the load
side of the conductor. The colored arrow will be on the source side of the conductor being monitored and MUST be pointed in a clockwise direction around
the conductor being monitored. Tighten the nylon clamp to complete the assembly.
Fig. 5. Arrow On The Current Sensor Assembly.
IMPORTANT:
When looking from the source side of the conductor(s) being monitored, you
should see the arrow on the current sensor assembly. The arrow should be
pointing in a clockwise direction around the conductor(s) being monitored. If
the arrow is not positioned on the source side, inaccurate readings will result.
62-0389-05 12
CLASS 2000 METER
4.3.2 Installing the Solid-Core Current Sensor Assembly
The optional solid-core current sensors can be installed in the same applications as
the standard split-core units, however, the conductors that they are monitoring must
first be disconnected.
NOTE: Under no circumstances is this operation to take place without shutting
off the power to the conductor(s) being monitored.
With the power off, disconnect the conductor from its breaker or terminal. Slide the
solid-core current sensor over the conductor, making sure that the indicator on the
sensor is pointing in the direction of the load. After this is done, reconnect the
conductor and verify that it is properly installed.
Run the black and white wires from the solid-core current sensors and install them
according to the standard installation diagram. When this is completed, the power to
the monitored conductor can be turned back on.
Fig. 6. Solid-core Current Sensor.
4.3.3 Current Sensor Wiring
Once all the current sensors are installed on their appropriate phase conductors, you
can begin terminating the current sensors on to the Class 2000 main power board.
The current sensor leads can be extended up to 2,000 feet (using #14-22 AWG wire)
for remote monitoring applications. Consult your local electrical codes for proper wire
sizing (#22 AWG twisted pair wire with a black and white conductor, rated for 600 VAC
recommended.)
The current sensor connection points are located on the bottom right of the main
power board. Three removable plugs exist, one for each current sensor phase input.
The header portions of the connectors are labeled A, B and C. Text on the plastic cover
of each of the connectors instruct you which terminal of the plug is for the white
conductor and which terminal is wired to the black conductor. Once each current
sensor is wired to its respective plug, insert each plug into the appropriate header,
verifying polarity as they are installed (see section 4.6).

62-0389-05 18
CLASS 2000 METER
5.0 MONITORING MULTIPLE LOADS WITH ONE METER
The Class 2000 meter provides extreme flexibility by allowing additional sets of current
sensors to be used in parallel so that multiple load locations can be monitored by one
meter. This feature allows a totalized display readout from two or more load circuits.
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.
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, with a maximum of
three sensors installed in parallel per phase.
Rule 2: All sensors used in parallel must be of the same amperage rating (i.e. 100
amp, 200 amp, etc.) The rating is determined by the current rating (amperage) of the
Class 2000 meter. For example, a 200 amp meter 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 cannot monitor a 208 volt load nor can a meter monitor two 480 or 208 volt loads
if they are from different originating power sources or from different transformers.
Rule 4: The display readings must be multiplied by the number of sets of current
sensors installed. E.g. meter reading of 5 kWh with 2 sets of current sensors....5 x 2 =
10 kWh (actual usage.)
NOTE: One set of current sensors equates to three sensors, one per phase.
The multiplier only applies when extra sets of current sensors are
installed on one meter. Therefore, if you are using only one set of three
sensors (one per phase) the multiplier is not required.

6.2 How to Read the kWh Meter
Fig. 17. Readings are Displayed in Whole Numbers.
The Class 2000 kWh meter displays readings in whole numbers, there are no
decimals.
To find the dollar cost for the power used by the load(s) being monitored, you must first
find out what the cost per kWh is in your area (this cost can be found on your utility
electric bill, or call your local utility and ask for their cost per kilowatt hour.) Simply
multiply the cost per kWh by the kWh reading from the E-Mon D-Mon meter. The
resultant figure is the dollar cost for power used by the load(s) being monitored by this
meter.
Example:
8-digit display reading 00000017
Cost per kWh from utility $0.12100
17 x $0.121 = $2.06
NOTE: THE FOLLOWING ONLY APPLIES TO METERS USING MORE THAN ONE
SET OF CURRENT SENSORS. For meters using parallel current sensors
you must multiply the kWh display reading by the number of sets of current sensors installed.
Example: 250 (meter display reading) x 2 (sets of sensors in parallel) = 500 kWh 500
kWh x $0.121 (utility cost per kWh) = $60.50

Pulse output signal is a 50/50 duty cycle. This means that whatever the time is
between pulses (based on load) the ON time will be 50% of that time. As an example,
if there were 9 seconds between pulses, the ON time would be 4.5 seconds. The OFF
time would be of the same amount.

There is no voltage on the output of the pulse connection. It is referred to as a “dry”
contact. It is, however, not a physical contact. As an electronic contact equivalent,
there is a polarity associated with it because it is designed to function with a DC signal
from the BAS. The interface range is from 4.5 to 28 VDC, with a maximum of 50 mA.

7.0 KWH/DEMAND METER FEATURES & FUNCTIONS*
(*Applies to meters equipped with the Demand Option [-D-],
for example: E20-208400-J-D-KIT.)
7.1 KWh/Demand Meter Display Functions
The Class 2000 kWh/Demand meter has a single display window that cycles through
the energy data screens. The meter will cycle through five (5) separate screens. The
screens are described below.
KWh display shows the amount of energy
consumed in kilowatt hours (kWh). Reading is
in whole numbers, there are no decimals and
the meter requires no multipliers.
LOAD display shows the present circuit load
in kilowatts.
KW display shows the electrical Demand in
kilowatts (kW). Demand interval is either 15
minutes, 30 minutes or 60 minutes. (Default is
15 minutes.)
Time display shows the time of the day that
the demand peak occurred.
Date display shows the date of the demand
(kW) peak.

CLASS 2000 METER
7.2 How to Read the kWh/Demand Meter
Fig. 22. KWh Reading.
The Class 2000 kWh meter displays readings in whole numbers, there are no
decimals.
To find the dollar cost for the power used by the load(s) being monitored, you must first
find out what the cost per kWh is in your area (this cost can be found on your utility
electric bill, or call your local utility and ask for their cost per kilowatt hour.) Simply
multiply the cost per kWh by the kWh reading from the E-Mon D-Mon meter. The
resultant figure is the dollar cost for power used by the load(s) being monitored by this
meter.
Example:
8-digit display reading 00000017
Cost per kWh from utility $0.12100
17 x $0.121 = $2.06
Fig. 23. KW (Demand) Reading.
The kW (Demand) reading is the peak usage over a specified time period (15 minute
standard, 30 minute and 60 minute optional). While kWh costs are interpreted as
cents, Kilowatt costs are usually represented in dollars, and interpretation of demand
costs are based on your utility’s tariff and rate structures. You will need to contact your
utility to see how your utility structures their kilowatt demand charges to ensure proper
allocation of costs utilizing data from the E-Mon D-Mon meter.
NOTE: THE FOLLOWING ONLY APPLIES TO METERS USING MORE THAN ONE
SET OF CURRENT SENSORS.
For meters using parallel current sensors you must multiply the kWh display reading by
the number of sets of current sensors installed. With Demand meters, the PEAK
Demand is also multiplied by the number of sets of current sensors installed.
Example:
17(meter display reading) x 2 (sets of sensors in parallel) = 34 kWh
34 kWh x $0.121 (utility cost per kWh) = $4.12

CAUTION
10.1 Line Voltage Diagnostics
E-Mon meters detect the direction of rotation of three-phase power. The proper phase
sequence must be A-B-C.
The AC power input must be in proper phase sequence A, B, C. If incorrect, the display
will read “Check Install.” See Fig. 28.
Fig. 28. Check Install Error.
How to Verify & Resolve a Phase Sequence Error
Dangerous voltage is present inside the meter!
The following steps are for Qualified Electrical Service Personnel only.
1. Have the electrician unplug or disconnect all three current sensors at the meter
input terminal.
2. If the meter still displays “Check Install” without any sensors connected the
utility power or transformer is connected counter clockwise (CBA) reverse phase
rotation.
3. Disconnect the power to the meter line voltage inputs. Swap A & C line inputs.
Power up the meter and verify there is not a “Check Install” displayed on the LCD
screen.
4. If reverse rotation line condition was present in step 2 and corrected in step 3
then swap the sensor inputs plugs A and C. Plug sensor “A” plug into the sensor
“C” input and plug sensor “C” plug into the “A” input. This will now match the line
phase correspondence.
NOTE: A light load or no load can cause the “Check Install” message to be dis-
played.
62-0389-05 38
CLASS 2000 METER
A light load or circuit with no load will cause the “Check Install” to be displayed, for
example a transformer with no load. The meter must have at least 1% load for each
current sensor. For example model number E20-208200-(J or R)-KIT is 200 amp rated;
each of the current sensors must have at least two amps flowing though them to verify
installation. If the “Check Install” message goes off with 1% or more load, then there is
no issue with installation. “Check Install” was due to a light load; this is normal and will
turn back on during light load condition.
Intermittent “Check Install” message displays for a while and then goes off? This is
very typical with air conditioning monitoring applications. With modern air conditioning
systems a condenser coil-cooling fan runs on single-phase power and the compressor
runs off three-phase power. The “Check Install” displays when the fan is running and
will remain on until the compressor motor cycles back on. This is to be expected and is
normal.
“Check Install” display is still on with 1% load and phase rotation sequence A-B-C
verified in steps 1-4, then check for correct Current Sensor Installation.
Is the Current Sensor(s) clamped around the wire backwards?
Assemble the current sensor halves around the conductor(s) to be monitored. Ensure
each of the current sensor halves marked “Load” (Load Side is shown with two arrows
see Fig. 29) are both facing the load side of the conductor. (The load is the side of
the conductor where the equipment you are monitoring is located.)
When removing the spit-core Current Sensor halves, DO NOT cut the tie wrap! The
head of the cable tie has a release tab. Push down on the tab to release the green
colored core.
39 62-0389-05
CLASS 2000 METER
How do I know line from load?
Generally speaking, “line” is the power coming in or “upstream” to a circuit breaker/
fuse/disconnect/etc. “Load is the power going out (“downstream”) of the device that
interrupts power. If you put a voltage meter on each side (presuming that your switch/
breaker/fuse/whatever is working correctly), then when you switch it on and off, the
load side is what goes on and off and the line side is what stays hot no matter what
(see Fig. 29).

11.0 HIGH VOLTAGE METERING
kWh Meter Installation Instructions for Use with E-MON Meters in High Voltage Applications
The E-MON model number containing “12025HV” kWh meter is designed to be used
for monitoring high voltage (2400, 4160, 13200, etc) circuits, either “stand alone” or in
an AMR application.
This meter is intended to be used with the appropriate high voltage Potential
Transformers (PTs) and Current Transformers CTs) supplied by others. The meter
application is centered around a 120 VAC secondary output from the high voltage PTs
and a 5 amp secondary output from the high voltage CTs.
Items addressed by this document include the installation of meters with model
number containing “12025HV” on high voltage circuits as well as the calculations to
provide the correct meter multiplier based on the PT and CT sizes used on the high
voltage conductors.
Installation should be performed by qualified personnel and only according to all
applicable electrical codes.
High Voltage CTs (supplied by others) reduce the primary current (amps) to a directly
proportional 0~5 amp secondary output. As an example, a 0~400 amp primary
becomes a 0~5 amp proportional signal from the secondary output. In our application,
the high voltage CT secondary is installed as a continuous “loop”, with a single
conductor connected to both secondary terminals.
To convert the 0~5 amp signal to a 0~ 2 volt signal, E-MON’s Current Sensors are
installed on the CT secondary conductor. A set of 25 amp sensors is used in this
application. These sensors have the high voltage CT secondary conductor passed
through them five (5) times (see below) by looping the secondary conductor as shown
in the drawing. The reason for this is so that the 5 amp secondary now appears to the
current sensor as a 0~25 amp signal. This creates a conversion of the CT’s primary
current to a directly proportional 0~ 2 volt signal which is utilized by the E-MON meter.
The example from the first paragraph has now become a 400 amp to 2 volt device, by
this technique.

CLASS 2000 METER
This special high voltage meter installation shows the correct wiring procedure for 3wire high voltage circuits. In this application, the 2 element meter connection is used
on the secondary circuits of the user supplied high voltage PTs and CTs.
The E-MON meter used in this application is the model containing “12025 HV”.
Installation of these meters requires the use of two (2) current sensors mounted on the
secondaries of the high voltage Current Transformers. See the drawing above for
proper wiring. For correct operation, the meter must be installed correctly.
This special high voltage meter installation utilizes high voltage PTs (Potential
Transformers) and CTs (Current Transformers) supplied by others. The E-MON meter
is installed using the secondary outputs of these devices.
High voltage PTs reduce the primary voltage (4160v, 13200v, etc.) to a Secondary
output of 120v. This secondary is connected to the E-MON meter voltage inputs as
shown in the wiring diagram. High voltage CTs reduce the primary current (amps) to a
directly proportional 0~5 amp output. As an example, a 0~400 amp primary becomes a
0~5 amp proportional signal from the secondary output. This allows much smaller
wiring to be utilized in the meter hookup. The high voltage CT secondary is installed as
a continuous “loop”, with a single lead connected to both secondary terminals.
E-MON meters accept a 0~2 volt signal from their Current Sensors. To convert the 0~5
amp signal, the Current Sensors are installed on the CT secondary lead. A set of 25
amp sensors is used in this application. These sensors have the high voltage CT
secondary lead passed through them five (5) times by looping the wire as shown in the
drawing. This allows a direct conversion of the CTs primary current to a directly
proportional 0~2 volt signal, which is used by the meter.
Since there is a signal ratio introduced by the high voltage CTs and PTs, it will be
necessary to multiply the number on the meter’s display for a correct reading. The
meter multiplier is calculated by using the CT ratio and the PT Ratio. [PTr x CTr /
Number of Secondary Lead Passes Through Sensor]. The E-MON 25 amp HV kWh
meter with 5 wraps of the high voltage CT secondary will have its multiplier calculated
by the formula shown below.
EXAMPLE: CT = 400:5 = 80:1 (CTr = 80)
PT = 4200:120 = 35:1 (PTr = 35)
Wraps (Passes) = 5
METER MULTIPLIER = PTr x (CTr/Wraps)
35 x (80/5)
35 x (16) = 560

12.0 FREQUENTLY ASKED QUESTIONS
Q. When providing line voltage to the meter, can I tap off of the same breaker I am
monitoring?
A. Yes, the voltage can be pulled from the same breaker being monitored.
Q. Can the meter’s line voltage wires be run in the same conduit as the sensor leads?
A. Yes, there will be no effect on the meter if the sensor leads and line voltage wires
are run in the same conduit.
Q. Can the meter communication wires and line voltage wires be run in the same
conduit?
A. It is NOT recommended to run these wires together due to noise concerns and their
effects on the communications signal integrity. Communication wires can be routed
separately using the 1/2” conduit port.
Q. How do I find the cost for kWh and kW to bill my tenants?
A. Your local utility bill should list the cost per kWh and kW. If not, simply call your utility
and ask them to provide you with the cost per kWh and kW.
Q. What size wire do I use for the line voltage leads?
A. These wires are normally #14 AWG, but be sure to consult your local electrical
codes for proper sizing requirements.
Q. What size wire should I use to extend the current sensor leads?
A. These wires are normally sized at #14-22 AWG, twisted pair arrangement. Consult
your local electrical codes for proper sizing requirements.
62-0389-05 44
CLASS 2000 METER
Q. The load I need to monitor has parallel feeds. How do I install the current sensors
for this application?
A. There are two ways you can monitor parallel feeds. One method is to clamp the
sensors around all feed wires for each phase (no additional reading multiplier
required). The second way to monitor parallel feeds is to clamp the sensor around one
of the feed wires for each phase, and when you read the kWh meter the final reading
must be multiplied by the number of feed wires for each phase.
Q. I have two subpanels 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 different
power sources. When you parallel current sensors, all loads 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 run through the A phase sensor, and the same for B & C
phases. The meter should be sized by the highest amount of current being monitored
by one sensor.
Q. I’ve gone through the troubleshooting guides and I still can’t get my meter to work.
What should I do?
A. Before removing the unit, contact E-Mon’s technical support department at (800)
334-3666. Our technical support experts will assist you in detailed troubleshooting of
the meter installation and assist you in getting the meter functional without having to
remove and return the unit.
