GREEN CLASS METER 1.0 PRE-INSTALLATION INFORMATION The E-Mon D-Mon® Green Class kWh/Demand meter is a 3-element meter used to monitor electric power usage of individual loads after the utility meter. Installation must only be performed by qualified personnel and in accordance with these instructions and all applicable local and national electrical codes. E-Mon or its representatives assume no responsibility for damages or injury resulting from the improper installation of this meter.
GREEN CLASS METER CAUTION Internal circuit card components are extremely sensitive to electrostatic discharge. Prior to handling or touching internal circuitry, discharge any static buildup on your person. To discharge yourself, touch a grounded metal object such as conduit or an earth grounded metal enclosure.
GREEN CLASS METER 1.1.1 Main Power Board Connections to this board include the MAINS Input Voltage, Current Sensors, external IDR interface and Isolated Pulse Output. The MAINS input terminals are covered with a protective shield for safety purposes. The current sensor assemblies interface to three header connectors, labeled A, B, and C along with conductor color indication.
GREEN CLASS METER 3.0 PRECAUTIONARY AND SAFETY INFORMATION CAUTION Internal circuit card components are extremely sensitive to electrostatic discharge. Be careful not to touch internal circuitry prior to discharging any static buildup on your person. To discharge yourself, touch a grounded metal object such as conduit or an earth-grounded metal enclosure. WARNING High voltages present on main PCB terminal block TB1 screw terminals. Risk of serious injury and/or electrical shock exists.
GREEN CLASS METER 4.0 METER INSTALLATION 4.1 Mounting the Meter Using the appropriate sized mounting hardware, fasten the Green Class meter enclosure to the selected mounting surface. The four mounting holes are centered 6.75” H x 4” W. The mounting hole spacing is identical for either the UL Type 1 or NEMA 4X enclosure. NOTE: Only the NEMA 4X enclosed unit is suitable for outdoor environmental conditions.
GREEN CLASS METER 4. 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. This exception is that the conduit and fittings for outdoor installations require an outdoor material rating and approval for 4X applications. Unit MAINS Wiring (Voltage Wiring Connections) a.
GREEN CLASS METER 8. Using an AC Voltmeter, verify the input voltage readings are within the limits specified below. Meter Input Voltage Configuration Nominal Voltage Limits (+/- 10%) 120/208V, 3 Ph, 4 Wire 120 VAC (L-N) 108 to 132 VAC 277/480V, 3 Ph, 4 Wire 277 VAC (L-N) 249 to 305 VAC 240V, 3 Ph, 3 Wire 240 VAC (L-L) 216 to 264 VAC 480V, 3 Ph, 3 Wire 480 VAC (L-L) 432 to 528 VAC 347/600V, 3 Ph, 4 Wire 347 VAC (L-N) 540 to 660 VAC 9.
GREEN CLASS METER 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. 3. Split-Core Current Sensor Assembly 1. Reassemble the current sensor assembly around the conductor(s) to be monitored.
GREEN CLASS METER 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.

GREEN CLASS METER 4.5 Line Voltage/Current Sensor Diagnostics M33181 Fig. 8. Main Board The three-phase AC MAINS voltage wiring and the current sensor wiring must be connected in the proper phase sequence. If there is a phase sequence error, the display LCD will display a message ‘Check Sensor” in the upper right hand corner. Additionally, LED D1, Check Sensor, will illuminate if there is a phasing error. Verify that the AC MAINS voltage wires are all connected to the correct positions on terminal block.
GREEN CLASS METER Verify each current sensor by running at least 1% of the full scale rated current through the conductor being monitored by each phase. (e.g. 2 amp load required for each phase to perform sensor diagnostic procedures.) - Verify that the current sensor white and black conductors are installed in the correct header positions. - Verify the current sensors are installed in the correct direction on the conductor being monitored.
GREEN CLASS METER 5.0 MONITORING MULTIPLE LOADS WITH ONE METER The Green Class 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.

GREEN CLASS METER 6.2 How to Read the kWh Meter Fig. 13. Readings are displayed in whole numbers The Green Class 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.
GREEN CLASS METER 6.3 KWh Meter Hardware Functions IDR Jack 8-pin RJ-45-used to connect kWh meter to the E-Mon Energy automatic meter reading system. Calibration Jack Connector J11 is for factory calibration only, and is not a user accessible port. Silicon plug is not to be removed. Error LED When lit, indicates that the current sensor is backwards or on the incorrect phase. Meter Pulse LED Blinks to show the meter load. Blink rate increases with load.

GREEN CLASS METER 10.0 TROUBLESHOOTING GUIDE The Green Class kWh/Demand meter is calibrated and tested at the factory before being packaged and shipped. If installed properly and in accordance with these installation instructions, your Green Class meter should provide years of trouble free service. If the meter should not function, the following guide will assist in troubleshooting the installation. Problem Procedure to follow 1. Display window is blank. Check wiring to voltage terminals.
GREEN CLASS METER 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 on the meter if the sensor leads and line voltage wires are run in the same conduit. Q.
GREEN CLASS METER 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.
