CLASS 2000 METER 10.0 TROUBLESHOOTING GUIDE The Class 2000 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 Class 2000 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.
CLASS 2000 METER 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 CAUTION Dangerous voltage is present inside the meter! The following steps are for Qualified Electrical Service Personnel only. 1. 2. 3. 4.
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.
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). Fig. 29.
CLASS 2000 METER 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.

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.
CLASS 2000 METER 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.
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).
