Over view
1.1 Product Description
The GE Multilin EPM 5100 Electronic Power Meter is a full-function electronic meter with
optional pulse initiation and communications features. The communications option
supports the ‘open-architecture’ Modbus protocol and can be easily installed in the field at
a later date. The EPM 5100 is available with the following mounting options:
• An industry-standard SI-compatible case to maintain drawout capability, allowing
for easy upgrade or retrofit from existing DS-63, DS-64, or DS-65
electromechanical watthour meters (case type unit).
• A light compact plastic enclosure for panel mounting (panel mount unit).
The EPM 5100 continuously monitors specified line characteristics and displays the desired
functions and calculated values on a two-line, alphanumeric liquid crystal display (LCD) on
the front panel. The meter samples each of the current and voltage inputs 480 times per
second, and the display is updated every three seconds.

CHAPTER 1: OVERVIEW
1.3 Physical Description
1.3.1 Front Panel
The front panel has a two-line, 16-character per line LCD and a three-button keypad for
view data and configuring the meter. The communication port and the voltage, current,
and pulse initiation terminals are located on the back of the meter.
The front panel contains the following features:
• A 3.8" by 0.9" two-line LCD that can display up to 16 characters per line.
• Three pushbuttons for scroll up, scroll down, and alternate scroll/enter. Operating
procedures for these buttons are described in Chapter 3.
• An additional secret button for accessing the Program mode. Operating
procedures for the Program mode are described in Chapter 4.
• A complete list of available metering and a display contrast-adjustment knob are
located under a flip-down door.
1.3.2 Display
Any of the metered functions can be viewed by pressing the SCROLL buttons or allowing the
EPM 5100 to automatically scroll through the parameters. All metered values are updated
every three seconds, whether or not they are being displayed at the time. Press the SELECT/
ENTER button to toggle between the normal and alternate scrolls.
1.3.3 Back Panel
The meter interconnections are located on the back panel as shown in the following figure.
These include:
• Terminal studs for the voltage and current inputs.
• Two terminal blocks for the optional pulse initiation outputs.
• A Power Leader communications port.

1.3.4 Panel Mounting
The EPM 5100 is designed to mount semi-flush on motor control center, switchboard, or
switchgear accessory doors or panels within easy reach of an operator. The cutout for the
EPM 5100 is shown below and is identical to the industry-standard SI case for DS-63 and
DS-65 electromechanical watthour meters. The case has four mounting holes that accept
#10-32 ×3/8" (plus mounting panel thickness) screws. The meter is mounted through the
front of the door or panel. The EPM 5100 may be installed on an existing DS-64 cutout
using the PLE2ADPG01 adapter plate.
Do not use screws longer than 3/8" plus the mounting panel thickness. Longer screws may
damage or interfere with the front panel retaining tabs.

CHAPTER 1: OVERVIEW
1.5 Applications
1.5.1 Typical Applications
The EPM 5100 Electronic Power Meter can be used on three- or four-wire, three-phase
systems having a nominal frequency of from 45 to 65 hertz. See the order code table
above for configurations. The EPM 5100 Electronic Power Meter accepts the following
combinations of inputs:
• two voltage inputs and two current inputs for three-phase, three-wire delta
systems
• two or three voltage inputs and three current inputs for four-wire wye systems
Potential transformer (PT) primaries may be connected line-to-line or line-to-neutral. Two
PTs, connected open delta, can be used for a line-to-line connection.
PT and current transformer (CT) ratios are configured in Program mode. With these ratios
configured, the EPM 5100 Electronic Power Meter automatically calculates primary
currents, voltages, power, and energy.
1.5.2 PT and CT Inputs
The EPM 5100 Electronic Power Meter can be ordered to accept direct voltage inputs from
69 to 600 volts. For system voltages greater than 600 V, the customer must supply external
PTs. The PT turns ratio is configured in Program mode and has a range of 0.5:1 to 9999:1.
See PT Ratio on page 4–16 for details on setting the PT ratio.
The meter current inputs are rated at 5 A AC, nominal. The customer must supply the
external CTs. Fourth-wire neutral CT inputs are not accepted; however, the EPM 5100
Electronic Power Meter calculates and displays the neutral current. The CT turns ratio is
configured in the Program mode and has a range of 0.5:1 to 99,999:1. See CT Ratio on
page 4–16 for details on setting the CT ratio. The meter has a continuous overload
capability of 10 A and a CT burden of 0.25 VA.
