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)

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.

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.
