AcuRev 2000 Series Install Guide

We walk you through the key steps to installing AcuRev 2000 series multi-circuit power meters in a number of configurations.


Voltage and Current Connection

The AcuRev 2000 series can be installed using three common installation methods with the External CT (EM) Module or the Internal CT (DM) Module. The meter configurations and diagrams are displayed below.

Three Phase: 4 wire-connection (Three phase with a neutral)
Common Voltages for this connection: 208LL/120LN, 600LL/347LN

External CT (EM) Module

The system you are monitoring has a voltage lower than 400V LN or 690V LL and you are using the DM Module current input, the connection diagram is shown below.

Figure 1: External CT (EM) Module Metering Configuration – 3LN


Internal CT (DM) Module

The system you are monitoring has a voltage lower than 400V LN or 690V LL and you are using the EM Module current input, the connection diagram is shown below.

Phase CI7I8I9I16I17I18
Single Phase: 2 Lines (Single phase with one line and a neutral)
Common voltage for this connection: 120V

External CT (EM) Module

Using the EM Module current input, the connection diagram is shown below.

Power Supply Connection
Caution: Check the silver sticker on the side of the meter to confirm which power supply option the meter supports before energizing it. The silver sticker will list details such as the model number, power supply, voltage/current inputs and serial number.

To power on the meter connect the power supply terminal as shown in Figure 7
