CHAPTER 2
ELECTRICAL INSTALLATION
2.1
CONNECTING THE CURRENT CIRCUIT
The cable used for the current should be installed at 600V AC minimum. The cable connector should be rated at 6
Amps or greater, and it should have a cross-sectional area of 16 AWG.
The current transformers should be mounted as close as possible to the meter. The following table gives the
maximum recommended distances for various CT sizes, assuming the connection is made via 16 AWG cable.
CT SIZE (VA)
2.5 VA
MAXIMUM DISTANCE (CT TO EPM3000P)
10 FEET
15 FEET
30 FEET
40 FEET
60 FEET
120 FEET
5.0 VA
7.5 VA
10.0 VA
15.0 VA
30.0 VA
WARNING: DO NOT LEAVE SECONDARY OF CT WHEN PRIMARY CURRENT IS FLOWING. THIS MAY CAUSE HIGH VOLTAGE,
WHICH OVERHEATS THE SECONDARY OF THE CT. IF THE CT IS NOT CONNECTED, PROVIDE A SHORTING BLOCK ON THE
SECONDARY OF THE CT.
2.2
CONNECTING VOLTAGE CIRCUIT OF POTENTIAL TRANSFORMER
For proper operation, the voltage connection must be maintained. If an error occurs, such as mistaking Line A for
Line B, a PH message appears, indicating a Phase Reversal (see Phase Imbalance and Reversal).
The cable required to terminate the voltage sense circuit should have an insulation rating greater than 600V AC and a
current rating greater than 0.1 A.
2.3
SELECTING THE VOLTAGE FUSES
We recommend using fuses, although connection diagrams do not show them. Slow blow, 200 mA rating fuses
should be used.
The maximum voltage EPM3000P can handle 150V phase to neutral. If Suffix -G is added to the model number, the
maximum voltage to be used is 300V phase to neutral.
2.4
CONNECTION TO THE MAIN POWER SUPPLY
The EPM3000P requires a separate power supply connection. Listed are the 5 different power supply options and
corresponding.
NOTE: FOR DC-POWERED UNITS POLARITY MUST BE OBSERVED. AN EARTH TO GROUND CONNECTION TO CHASSIS IS
MANDATORY FOR NORMAL OPERATION (TERMINAL 3). DO NOT GROUND THE UNIT THROUGH THE NEGATIVE OF THE DC SUPPLY.
SEPARATE GROUNDING IS REQUIRED.

ELECTRICAL CONNECTION INSTALLATION
Choose the diagram that best suits your application and maintain the polarity. Follow the outlined
procedure to verify correct connection.
NOTE: THE NEUTRAL READING IS CALCULATED FROM THE SUM OF THE 3 PHASES OF CURRENT. HIGH NEUTRAL
CURRENT INDICATES REVERSE CT POLARITY.

ACCESSING THE LM1/LM2 SET LIMITS FROM OPERATING MODE
The DMVA100 is designed with two manual set limits. The set limits monitor the instantaneous readings, warning the
user of abnormal conditions. Each limit can detect readings above or below the set level. SET LIMITS: the point when
the relay changes position, if the DMVA100 is equipped with the Relay Option (Suffix -NL).
If a limit is exceeded, the annunciator LM1 and/or LM2 indicator glow and the display flashes, alternating between the
instantaneous reading.

VOLTAGE PHASE REVERSAL AND IMBALANCE FROM OPERATING MODE
In a three phase power distribution system, the normal phase shift between each line is 120°. The EPM3000P
detects an abnormality and displays a PH message every six seconds.
VOLTAGE PHASE REVERSAL:
If there is an incorrect connection, such as mistaking line A for line B, a PH message appears. The correct sequence
is a-b-c.
VOLTAGE PHASE IMBALANCE LIMIT:
Can be detected using the phase imbalance limit in the Programming Mode. The phase imbalance is expressed in a
percentage with 0% indicating a 120° phase shift between each line. A PH message appears if the limit is exceeded.

PROGRAMMING GROUP 2: METER CALIBRATION
9.1
STANDARD CALIBRATION
WARNING - READ THIS SECTION CAREFULLY BEFORE PROCEEDING
⌦
⌦
Calibration does not need to be accomplished to change CT or PT ratios. (See GROUP 1).
Meter calibration cannot be performed if the meter is installed for service. The sensing must be
connected to a power supply with variable voltage and separate current outputs.
⌦
⌦
⌦
The calibration procedure requires highly accurate and stable input signals. Incorrect
readings result from improper calibration procedures. If unsure, return unit to the factory for
calibration.
BEFORE calibrating any channel, make note of its Full Scale Setting (see Ch. 8). Set the Full
Scale in accordance with Table 9-1 for calibration. Restore original Full Scale Setting when
calibration is completed.
The first function in GROUP 2 (STD.CORR) is NOT to be changed by the user. Please make
note of the value here (ꢀꢀꢀꢀ) before using any other function in this Group. If the STD.CORR
value is inadvertently lost or changed, contact the factory for assistance.
All sensitive electronic measuring devices drift slightly over time, requiring periodic calibration. We recommend
returning the meter to the factory on a yearly basis.

PROGRAMMING GROUP 7: PHASE REVERSAL & PHASE IMBALANCE
SET LIMITS/RELAYS
11.1
VOLTAGE PHASE REVERSAL AND PHASE IMBALANCE
The set limit alerts the user of an unbalanced or a reversed phase in a Three-phase System. The EPM3000P has two
options for this purpose.
PHASE REVERSAL:
Activates when a reversed phase enters the EPM3000P’s metering system.
PERCENT PHASE IMBALANCE:
Activates when the user’s present value percent phase imbalance is exceeded. For example: an unbalanced Three-
phase System.

TRIP RELAY
NOTE: THE -NL OPTION MUST BE PURCHASED TO HAVE RELAYS TRIGGERED FROM LIMIT CONDITIONS.
The EPM3000P has two Relays. These relays are linked through the program to Set Limits LM1 and LM2. The user
can program above or below set limits for every reading. When a measurement exceeds a particular value, the set
limit triggers and alerts the user. Each relay has provisions for a separate delay time (see Chapter 8).
