LECTRICAL INSTALLATION
2.1 C
ONNECTING 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) MAXIMUM DISTANCE (CT TO EPM3000P)
2.5 VA 10 F
5.0 VA 15 F
7.5 VA 30 F

ONNECTING 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 S
ELECTING 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.

All EPM3000P and EPM300P-F instruments can be equipped with: the EIA RS-232C or the EIA RS-485.
RS-232C communication links a single instrument with a computer or device such as an RTU or PLC. Its capability is up to 100 feet. A standard 9-pin female serial port connector mounts on the instrument for direct connection to a computer with a 9-pin cable.

Each EPM3000P has an unique address up to four digits long. This allows the user to communicate with up to 10,000 instruments. Standard baud rates are available up to 4800 baud. To select the proper baud rate, apply the following rules:
The unit operates up to 4800. For a smaller number of instruments over a long distance, use a lower baud. Optimal recommended baud rate is 1200 baud if noisy conditions exist.

The EPM3000P and EPM3000P-F measure 10 electrical parameters. Values for each parameter are accessed through the keypad on the meter's front panel (See
Figure 4.1
). The meters illustrated throughout the manual are EPM3000P except for Figure 4.1 below. The EPM3000P-F (Frequency Option) displays the Frequency measurement on the face of the meter. Max, Min and Limits indicators are on the left side of the face.

OLTAGE 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.

OW TO USE THIS PORTION OF THE MANUAL
This manual contains programming for basic operation, available options and parameters. Using the Table of Contents or “Quick Reference Guide”, find the programming feature location and read that chapter.
Programming tasks are arranged into nine major GROUPS. Within each GROUP are the specific meter FUNCTIONS. Outlined is the general approach to alter programming mode values.
1. Enter the Programming Mode.
2. Select the desired GROUP.
3. Select a FUNCTION within the GROUP.
4. After the FUNCTION selection, proceed with DATA ENTRY of the new value for the desired parameter.
5. Proceed to program another location and/or exit the programming mode.

TANDARD NUMERIC DATA ENTRY
Programmable FUNCTION values are always three digit numeric fields designed to accept any value between 000 and 1999. When entering the value of a function enter all three digits, leading zero's included. For instance, to enter 25, enter: 025.
When activating the Data Entry Sequence, certain Functions allow for a four digit entry. The display indicates a blank followed by three dashes (see diagram). The first digit may only be a 1 or a blank (the blank signifying 0). Press PRINT/PROG ONCE for 0, TWICE for 1.

TANDARD CALIBRATION
WARNING - R
⌦ 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.
T
The Full Scale and Calibration values should be equal during the calibration procedure. The meter may be rescaled without calibrating by changing the full scale in GROUP 1, FUNCTION 0 or 1. (See Table
