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

10.0 VA 40 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.

2.4 C

The EPM3000P requires a separate power supply connection. Listed are the 5 different power supply options and corresponding.

NOTE:

The EPM3000P allows the user to access a variety of relay options through the programming mode. The relay option package consists of two relays, which can be dedicated to alarm or communication (or both).

TIME DELAY

limit. The time delay can be programmed for any desirable duration.

If the relays are dedicated to communication, there are two different modes:



Lock ON Relay will not be affected by any alarm condition.



Lock OFF Relay will not be affected by any alarm condition.

If the relays are used for communication and alarm, there are four different modes:



Lock ON Relay stays on regardless of any alarm condition.



Lock OFF Relay stays off regardless of any alarm condition.



Free ON Relay turns on unless other conditions force it off.
