    CLASS 1000 METER 1.1. Internal Electronic Assemblies DISPLAY AND MAIN POWER KEYBOARD BOARD M33177 Fig. 1. Main Power Supply Board & Display Board The unit is comprised of a Main Power Board and Display and Keyboard. All component cards are mounted inside a UL Type 1 (standard) or NEMA 4X (optional) enclosure.

  • Page 6: Main Power Board

    CLASS 1000 METER 1.2 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.

  • Page 7: Precautionary And Safety Information

    CLASS 1000 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.

    CLASS 1000 METER 4.0 METER INSTALLATION 4.1 Mounting the Meter STEP 1: Using the appropriate sized mounting hardware, fasten the Class 1000 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.
  • Page 9 CLASS 1000 METER WARNING Failure to attach the protective earth ground wire securely to the enclosure creates a potential shock hazard. Do not operate the Class 1000 meter without a protective earth ground connection securely installed STEP 3: Wire Entry: Two openings exist on the unit enclosure, one for 1/2” conduit and one for 3/4”...
  • Page 10 CLASS 1000 METER 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 that no conductor wires are frayed or are shorting to adjacent terminal block positions.

    CLASS 1000 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.

  • Page 12: Installing The Split-Core Current Sensor Assembly

    CLASS 1000 METER 4.4 Installing the Split-Core Current Sensor Assembly STEP 1: 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.

  • Page 13: Installing The Solid Core Current Sensor Assembly

    CLASS 1000 METER 4.5 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.

  • Page 14: Current Sensor Wiring

    CLASS 1000 METER 4.6 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 1000 main power board. The current sensor leads can be extended up to 2,000 feet (using #14-22 AWG wire) for remote monitoring applications.

    CLASS 1000 METER 4.8 Line Voltage/Current Sensor Diagnostics M33181 Fig. 8. Main Board Configuration If the meter is not correctly wired, the “ERROR” indicator will be on. Verify that the AC MAINS voltage wires are all connected to the correct positions on the terminal block.

  • Page 17: Final Main Board Checks

    An open connection could exist at the plug terminals or at a splicing junction. Also verify a tight connection exists between the core halves. If error message is still appearing, contact E-Mon technical support at (800) 334-3666 for further assistance.

  • Page 18: Monitoring Multiple Loads With One Meter

    CLASS 1000 METER 5.0 MONITORING MULTIPLE LOADS WITH ONE METER The Class 1000 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.
