EPM 5100 ELECTRONIC POWER METER – USER GUIDE

CHAPTER 2: INSTALLATION

2.3

Electrical Installation

2.3.1

Instrument Transformer Connections

Wiring connections from CTs and voltage sources (up to 600 V AC) or PTs may be made 
with AWG wire sizes up to #10. Select the wire size according to conventional CT and PT 
circuit-design guidelines.

The figures in this section illustrate EPM 5100 Electronic Power Meter and instrument 
transformer connections for various combinations and configurations of PTs and CTs. CT 
and PT connections must be made using the polarity “dot” conventions shown on these 
figures for the EPM 5100 Electronic Power Meter to properly interpret power flows.

All current and voltage inputs (CTs and PTs) must be de-energized and the EPM 5100 
Electronic Power Meter completely assembled before connections are made to the 
meter.

All field wiring must be completed before power is applied to the EPM 5100 Electronic 
Power Meter terminals.
