1.1 Introduction
1.1.1 Description
The EPM 6000 is a multifunction power meter designed to be used in electrical substations,
panel boards and as a power meter for OEM equipment. The unit provides multifunction
measurement of electrical parameters.
The unit is designed with advanced measurement capabilities, allowing it to achieve high
performance accuracy. The EPM 6000 is specified as a 0.2% class energy meter for billing
applications as well as a highly accurate panel indication meter.
The EPM 6000 provides a host of additional capabilities, including standard RS485 Modbus
Protocol and an IrDA port remote interrogation.
1.1.2 Highlights
The following EPM 6000 features are detailed in this manual:
• 0.2% class revenue certifiable energy and demand metering
• Meets ANSI C12.20 (0.2%) and IEC 687 (0.2%) classes
• Multifunction measurement including voltage, current, power, frequency, energy
• Percentage of load bar for analog meter perception
• Easy-to-use faceplate programming
• IrDA port for PDA remote read
• RS485 Modbus communications

1.2 Features
1.2.1 Universal Voltage Inputs
Voltage Inputs allow measurement to 416 V line-to-neutral and 721 V line-to-line. This
insures proper meter safety when wiring directly to high voltage systems. One unit will
perform to specification on 69 V, 120 V, 230 V, 277 V, and 347 V systems.
1.2.2 Current Inputs
The EPM 6000 current inputs use a unique dual input method.
•Method 1 – CT Pass Through: The CT passes directly through the meter without
any physical termination on the meter. This insures that the meter cannot be a
point of failure on the CT circuit. This is preferable for utility users when sharing
relay class CTs. No burden is added to the secondary CT circuit.
•Method 2 – Current “Gills”: This unit additionally provides ultra-rugged
termination pass-through bars that allow CT leads to be terminated on the meter.
This, too, eliminates any possible point of failure at the meter. This is a preferred
technique for insuring that relay class CT integrity is not compromised (the CT will
not open in a fault condition).
FIGURE 1–2: Current Input Connections
1.2.3 Utility Peak Demand
The EPM 6000 provides user-configured Block (fixed) or Rolling window demand. This
feature allows you to set up a customized demand profile. Block window demand is
demand used over a user-defined demand period (usually 5, 15, or 30 minutes). Rolling
window demand is a fixed window demand that moves for a user-specified subinterval
period. For example, a 15-minute demand using 3 subintervals and providing a new
demand reading every 5 minutes, based on the last 15 minutes.

CHAPTER 1: OVERVIEW
Utility demand features can be used to calculate kW, kvar, kVA and PF readings. All other
parameters offer maximum and minimum capability over the user-selectable averaging
period. Voltage provides an instantaneous maximum and minimum reading which
displays the highest surge and lowest sag seen by the meter.
1.2.4 Measured Values
The EPM 6000 provides the following measured values all in real time and some
additionally as average, maximum, and minimum values.
