2.1 Main Power Board
Connections to this board include the MAIN Power Input and current sensors. The
MAIN Power Input terminals are positions one through four on the four position screw
terminal block, TB1. These terminals are covered with a protective shield for safety
purposes. The current sensor assemblies interface to the TB2, TB3 and TB4. Each
terminal block corresponds to an input voltage phase; care must be exercised to
ensure that each current sensor is connected to the correct terminal block. One three
terminal screw connector(TB42) is provided for RS-485 communications. One RJ-45
jack (J8) is provided for 10/100-base T Ethernet.
The contact is a solid-state switch for the phase-loss alarm function. Switching is
limited to 100 ma (0.1 amp) and voltage should not exceed 60 Volts AC or DC.
The (N.O.) contact closes within the meter due to the loss any one of the three lines of
voltage inputs to the meter. The contact closure may be used to activate an audible
alarm, light, control coil, or other indicator device. This alerts appropriate personnel to
the loss of voltage. An emergency phone dialer may also be programmed to send
notification automatically by phone, text, or pager. Alarming devices to be supplied by
others and are not included by with the E-Mon Class 5000 meter.
One two terminal screw connector provides phase loss alarming.
There are also two headers present for adding option cards. Header J3 is 20 positions
for use with an I/O board with up to two relays, two pulse inputs and two pulse out puts.
Header J4 is a 10 positions for use with modem and LonWorks TP/FT-10.

6.2 Main Power Board Connections
1. Installing a temporary ground for ESD protection: With all circuits de-energized,
connect a temporary protective earth ground connection for ESD protection.
Prior to performing any unit wiring, be sure to discharge any static on your person.
2. Installing the Class 5000 protective earth ground: Connect an earth ground wire
to the Class 5000 protective earth ground lug with a torque of 7 N-m. * for meters
in metal enclosures.
Failure to attach the protective earth ground wire securely to the meter creates
a potential shock hazard. Do not operate the meter without a protective earth
ground connection securely installed.
3. Wire Entry: One 3/4” conduit opening is located on the bottom of the unit enclosure. This opening is used for bringing in MAINS power and for current sensor
wiring. Route the appropriate cabling to and through the respective enclosure
opening.
4. After installing the conduit fitting and conduit, verify that each conduit slip nut is
securely tightened to its respective conduit fitting. Any unused openings must be
sealed with a UL rated plugging device suitable for the rating of the enclosure
(check formatting).
NOTE: Metallic enclosure has one additional 1/2” conduit opening at top of unit.
5. Unit MAINS wiring: The first four positions of terminal block TB1, located at the
bottom left corner of the main power board, are clearly labeled Phase A, B, C, N
(neutral). Earth Ground MUST be connected to the PCB mounting screw in the

CLASS 5000 METER
c. External Switch Mechanism/In-Line Fuse Installation.
To ensure a safe installation, the Class 5000 meter requires an external
switch mechanism, such as a circuit breaker, be installed on the Class 5000
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 5000 meter. 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.
d. Connect the three AC main power wires (Phases A, B and C) to their respec-
tive positions as labeled on terminal block TB1 and tighten to 7 in-lb. After all
conductors are connected to each of their respective terminal block positions
and tightened down, verify that each terminal block screw is securely fastened by gently tugging on each conductor.
NOTE: On Single phase connections: Connect two AC main power wires to
phases A and B - Connect jumper from B to C - factory installed for “-SP”
option. Verify that no conductor wires are frayed or shorting to adjacent terminal block positions.
e. Turn ON the AC main power input. The meter display will light up and scroll
through 7 displays. Each display is visible for 5 seconds. Display screens are
as follows:
Screen 1 - Total kilowatt-hours (kWh) consumed
Screen 2 - Peak demand (kW) with date & time stamp
Screen 3 - Actual load (kW) with preset date & time
Screen 4 - Average current (amps) per phase
Screen 5 - Average voltage (volts) per phase
Screen 6 - Average voltage (volts) phase to phase
Screen 7 - Power factor (PF) per phase
f. Verify the voltage readings on Screen 5 using an AC voltmeter. Typical read-
ings shown below are measured phase to neutral for 4 wire and phase to
phase for 3 wire. Readings should be +/- 10% of nominal.

6.3 Phasing of Line Voltage
The 3-phase AC power input must be in proper phase sequence. Single phase “-SP”
option - AC power input must be in proper phase sequence. If the sequence is
incorrect or a phase is missing, there will be a message on the meter’s display: “PH
Sequence Error” or “PH Missing:. (Refer to the section on Line Voltage Diagnostics if
this message is present.) When the line voltage is connected correctly, the meter’s
display will be blank (no message.)
Wait for the meter display to scroll to the voltage display. Verify that the meter reads
correct voltages on all three phases. Repeat Step 6.2.5.F.
Once the meter displays the correct line voltages and there are no error messages,
you are ready to connect the current sensors to the meter. Before continuing with the
installation, verify that the seven screens display as follows:
Screen 1 (kWh): Should read 0.0 kWh; if not, should be reset.
Screen 2 (kW Peak Demand): kW peak should read 0.0 kW. There will not be a
date/time stamp yet. If there is a kW peak recorded,
it should be reset later.
Screen 3 (Load/Clock Calendar): Should read 0.0 kW load.
Screen 4 (Amps per Phase): There should be 0.0 on all three phases. Or
in the SP option - 0.0 in A and B phases.
Screen 5 (Volts RMS Phase to Neutral): See the section 6.2.5.F.
Screen 6 (Volts RMS Phase to Phase): See the section 6.2.5.F.
Screen 7 (Power Factor Per Phase): There should be 0.0 PF on all three phases.
Or in the SP option - 0.0 in A and B phases.
NOTE: The meter will be reset later via the software during “startup” procedures.

6.4 Current Sensor Installation & Wiring
Once the AC voltages have been confirmed to be within acceptable limits, you are
ready to install the current sensors. TB2 is the input for Phase A, TB3 is the input for
Phase B and TB4 is the Phase C input. For the SP option: use TB1 pos 5&6 are for the
A Phase - TB1 pos 7&8 are for the B phase -factory installed jumper wire on positions
9&10. Factory installed Jumper should not be removed.
The Class 5000 meter can be used with two types of current sensors:
1. Split-core current sensor. This sensor opens so that it can be attached around
the circuit being monitored without interrupting power. Unless otherwise specified, all Class 5000 meters are supplied with this sensor type.
2. Solid-core current sensor. This sensor does not open and requires the monitored
conductor to be removed from the circuit to install the current sensor. This type is
only supplied when specified at time of order.
6.4.1 Installing the Split-Core Current Sensor Assembly
1. Each phase being monitored will require one two-piece current sensor assembly.
Open the two-piece current sensor assembly by releasing the nylon clamp using
a fl at head screwdriver.
Fig. 7. Split Core Current Sensor.
2. Reassemble the current sensor assembly around the conductor(s) to be monitored. 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.

LOAD
SOURCE
Fig. 8. Installation of a Split Core Sensor.
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.
6.4.2 Current Sensor Wiring
Once the current sensors are installed onto their appropriate phase conductors, you
can begin terminating the current sensors onto the Class 5000 main board. The
current sensors can be extended up to 500 feet for remote monitoring applications. To
extend the length of the wires, use #22 AWG twisted-pair wire with one white and one
black wire.
The easiest way to connect the current sensors is to use the meter’s built-in current
sensor diagnostics. To do this, there must be at least 1% of the meter’s current rating
(amps) fl owing in each of the conductors being monitored. The Class 5000 meter’s
diagnostic program will provide data to ensure that the current sensor installation is
done properly.
The current sensor connection points are located at the bottom right of the main power
board. These are terminals 5 through 10 of terminal block TB1. Each sensor connects
to two terminals, one labeled “Black” and the other “White.” Current sensors should be
connected to the meter one at a time and verified using the current sensor diagnostic
program.
Connect one of the current sensors to TB1 terminals 5 and 6 (Phase A). Wait 5
seconds and look at the meter display.
62-0392-0318
CLASS 5000 METER
6.4.2 Current Sensor Wiring (continued)
If the meter displays an error message (see below), remove the wires from terminals 5
and 6 and install them on terminals 7 and 8 (Phase B). if an error message occurs with
the sensor attached to terminals 7 and 8, try again on terminals 9 and 10 (Phase C).
The “CT Error: * “message will disappear when the current sensor is connected to the
correct terminals (phase).
Error Messages: CT ERROR: A
NOTE: The 1-Phase option will only display errors for A and B.
Refer to the section on Current Sensor Diagnostics for assistance in troubleshooting
these errors.
CT ERROR: A B
CT ERROR: A C
6.4.3 Main Power
After the meter circuit wiring has been examined for correctness, power may be
applied to the circuit board. There are three LEDs located in the upper right corner of
the Meter Board labeled BEAT, STATUS and LOAD. The BEAT and STATUS LEDs will
blink once per second when the meter is operating normally, twice per second if there
is a problem. If the monitored circuit is under load the LOAD LED will actively blink. A
heavy load will cause the LED to blink faster than a light load. Very light loads will
result in an extended blink time.

6.6 Line Voltage/Current Sensor Diagnostics
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.
6.6.1 Line Voltage Diagnostics
The diagnostics program detects line voltage faults by displaying one of two
messages:
PH Missing: B C or Phase sequence error.
PH Missing: B 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.
Phase sequence error
hooked up in the proper phase sequence. This message should never be seen
continuously on the display during normal operation. 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.
Indicates that the line voltage is missing on Phase B and/or Phase C.
: Indicates that the 1-phase or the 3-phase line voltage is not
2162-0392-03
CLASS 5000 METER
6.6.2 Current Sensor Diagnostics
The load current must be at least 1% of the meter’s rated load in order to use the
diagnostic function. Current sensor diagnostics can detect:
1. Reversed current sensors
2. Incorrect phase correspondence
3. Unusually low power factor (0.642 or lower)
CT Error: (ABC) is used to detect the swapping of current sensor phases. This
message could (in some rare cases) indicate a low (<65%) power factor condition. This
message may appear intermittently due to changes in line conditions. It should not 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
CT Error:
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

ways, check the AC voltage input 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.)
message disappears, you have found the correct sensor connection;
message does not disappear at any time while trying all 3 inputs both
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.

6.7 RS-485 Wiring (continued)
After performing these steps, all of the meters will be connected in a daisy chain
configuration. This network of meters can then be connected to the RS-485 network
and communication can be established.
Internal Modem
An optional internal modem inside one meter will communicate with the others via the
RS-485 network. Simply connect one of the two telephone jacks on the modem to the
telephone line to complete the installation.
Local Computer
A local computer installed in the building can communicate with the RS-485 network.
The computer must be connected to an RS-232 key. The RS-232 key is then
connected to an available RS-485 jack in the meter using an RJ-11 cable.
NOTE: Don’t confuse the modem’s telephone jacks with the RS-485 jacks!!!
NOTE: When using one meter with an external modem, only the telephone line is
connected. RS-485 is not needed.

6.8.3 Connecting Class 5000 Meters to the RS-232 Key using
RS-485
On the rear panel of the RS-232 key, there are three jacks labeled as channels A, B
and C. These are RS-485 serial communications ports used to connect the meters.
Each of these channels can be connected to as many as 52 individual meters over a
total cable distance of 4,000 feet. The channels are independent and must not be
connected to each other.
Modular Plug Method
This simple method requires using 4 stranded conductors inside a cable that is fitted
with an RJ-11 type plug for 4-conductor modular systems at each end of the cable.
*Do not use any pre-made telephone cables.
1. Plug the 4-wire RJ-11 cable/plug assembly into Channel A on the RS-232 key.
Connect the other end of this cable to the meter via the RS-485 port, (PORT 2)
at the bottom right of the Class 5000 meter main power board.
NOTE: The total combined cable length must not be more than 4000 feet.
2. Each meter has one yellow (TX) and one green (RX) LED located on the right

6.10 Modbus RTU Wiring
The Class 5000 Modbus meter communicates with building automation equipment
over a 2-wire (3-conductor) RS-485 network using Modbus RTU protocol. The meters
are networked in a daisy-chain configuration (Section 6.7) with BELDEN 1120A cable
or equivalent. The cable rating of 600V allows the RS-485 network to be connected to
480-volt meters. Up to 52 meters can be installed on a network string. The maximum
combined length of all daisy-chained cables must not exceed 4000 feet.
The meter-to-network connection is through the 3-screw terminal which is located on
the Main Power Board of the meter.
Fig. 16. Modbus R Wiring.
The meter is shipped with a Modbus ID number of 01. This must be changed if the
network has more than one meter installed. The change must be done before the
meter is introduced into the network. The meter can be numbered from 1 to 247. There
can be no duplicate numbers on a network, so caution must be taken when assigning
a meter ID number prior to its installation on the RS-485 network.

7.0 MULTIPLE-LOAD MONITORING
The E-Mon D-Mon Class 5000 meter provides extreme flexibility by allowing additional
sets of current sensors to be used in parallel so 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:
1. Current sensors must be installed in complete sets of three, with a maximum of
three sensors installed in parallel per phase.
NOTE:-In 1-phase option - sensors must be installed in set of 2 with maximum of
three sensors per phase.
2. All sensors used in parallel must be of the same amperage rating (all 100-amp,
all 400-amp, etc.) The rating is determined by the current rating of the meter. For
example, a 200-amp meter must use extra sets of 200-amp current sensors.
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 volt loads
if they are from different originating power sources or from different transformers.
4. 4. Multiply the meter display readings by the number of sets of current sensors
installed. Example: Meter readings of 5 kWh with 2 sets of current sensors - 10
kWh is the actual usage. (5 x 2=10.)
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. If you are using only one set of three current sensors, the multiplier is
not required.

11.0 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 if the sensor leads and line voltage wires are run in the
same conduit.
Q. Can the meter’s communication wires and line voltage 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. Communications wires can be
routed separately using a 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 sized at #14 AWG, but be sure to confirm this
requirement with your local and national electrical code requirements.
Q. What size wire should I use to extend the current sensor leads?
A. These wires are normally 14-22 AWG, twisted-pair arrangement. Consult your
electrical code for proper wiring requirements.
62-0392-0346
CLASS 5000 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. The easiest and preferred
method is to clamp the sensors around all feed wires for each phase. The second
way to monitor parallel feeds is to clamp the sensor around one of the feed wires for
each phase. When you read the Class 5000 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 Class 5000 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 with one meter because they are 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 class 5000 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 class 5000
meter to work. What should I do?
A. Before removing the unit, contact E-Mon’s technical services department at (800)
334-3666. E-Mon’s technical department will assist you in detailed troubleshooting
of the meter installation and assist you in getting the unit running without having to
remove and/or return it.

13.0 HIGH VOLTAGE METERING
kWh Meter Installation Instructions for Use with E-Mon
Meters in High Voltage Applications
The E-Mon model # 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 the 12025HV meter 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.

This special high voltage meter installation shows the correct wiring procedure for 4wire high voltage circuits. In this application, the 3 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 12025 HV.
Installation of these meters requires the use of three (3) 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
