Current Sensors EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 9 Part # E-Mon Meters Start-up Checklist See the checklist below. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 10 Part # E-Mon Meters 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. Sensor Arrow Color Code Brown Red Yellow Black Blue Blue Sensor Rating 100 Amp 200 Amp 400 Amp 800 Amp 1600 Amp 3200 Amp 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! Observe national and local electrical codes. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 11 Part # E-Mon Meters 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. Class 2000 and 5000 Screws should be securely fastened to all flanges of each device to ensure the device is safely attached to the wall or surface. MMU Use the following diagram to attach the different MMU models. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 12 Part # E-Mon Meters Figure 8. MMU Dimensions 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. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 13 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. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 14 Part # E-Mon Meters NOTE: Push the insulating cover down over the terminal block inside the meter. Apply voltage to meter only after installation is complete. Current Sensor This section provides you with various installation diagrams depending on your monitoring needs.

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. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 21 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.

Figure 22. Subtractive EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 28 Part # E-Mon Meters Figure 22. Subtractive connections 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. Multiple Loads Parallel Current Sensor Wiring Diagrams EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 29 Part # E-Mon Meters Figure 24. Monitoring two three-phase loads When reading the E-Mon D-Mon® meter, be sure to multiply the meter reading by the number of sets of sensors in parallel. Figure 25. Monitoring two two-phase loads EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 30 Part # E-Mon Meters 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. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 31 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. Breakout Within Panel Figure 26. Breakout within panel EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 32 Part # E-Mon Meters 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. High Voltage Installation (Above 600V) EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 33 Part # E-Mon Meters Figure 27. High voltage 0 Checking Installation o When testing a meter for proper installation, it is first necessary to determine if the meter is receiving the proper line voltage EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 34 Part # E-Mon Meters o o o o o o o o o o needed to be operational. 120 volt , 2-wire meter: deliver 120 volts to A phase voltage terminal 277 volt, 2-wire meter: deliver 277 volts to A phase terminal 208/240 volt 3-wire meter: deliver 208 or 240 volts to A and B phase voltage terminals 208 volt 3-phase meter: deliver 208 volts to A , B and C phase voltage terminals 240 volt 3-phase delta meter:240 volts between phases- neutral is not connected 480 volt 3-phase meter: deliver 480 volts to A, B and C phase voltage terminals 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, paper and pencil 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. EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 35 Part # E-Mon Meters Follow the procedure below to verify. 3. On the circuit board on the inside of the meter door, below the display, there is a row of small buttons. The third button from the 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. QAT kWh Meter Verification 1.

Pulse The output of the Class 2000 meter is not configurable. The Class 5000 does not have a pulse output. Troubleshooting Class 2000 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 For the latest technical documentation, visit www.novar.com/manuals 44 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.) EMONMETER- INS 2/16/2012 For the latest technical documentation, visit www.novar.com/manuals 45 Part # E-Mon Meters 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.
