Installation
2.1 Getting Ready
2.1.1 Determination of Metering System Requirements
Determine if the application is for a metering system or for a stand-alone meter. If the
application is for a stand-alone meter, please read Overview of Meter Wiring on page 2–2.
If the application is for a metering system, then also read Installing the Scan Transponder
on page 2–18.
2.1.2 Phase Association
As shown in Table 2–1: Wiring Diagram / Model Reference on page 2–3, there are four
wiring types for the EPM4500 meter. Each wiring type has a specific phase association
table to ensure that current transformers are in-phase with the reference voltage. These
phase association tables must be followed for the meter to function properly with the
chosen wiring type.
The phase association of the current transformers must be followed or meter will not
be installed correctly.
