3. Determine the number and types of meters or monitors required (single-phase,
network, or three-phase).
4. Determine the model number and correct sense voltage based on the voltage
label on the top right side of the unit.
Access to Power and Lighting
The installation site must be supplied with access to the main electrical panel and
any sub-panels. Portable or permanent lighting must be available to provide the
installers with a clear view of the equipment and of the installation environment.
Each installation may vary depending on physical site restrictions.
Installation Procedures
This section provides information about activities that must be performed to install
the PowerLogic EM4033 and EM4080 meters in a single-phase 2-wire,
single-phase 3-wire (network), or three-phase 4-wire application. The installation
procedures must be performed in the following order:
1. “Mounting the PowerLogic EM4000 meter” on page 7
2. “Installing Potential Transformers for Three-Phase Service Greater Than 277V”
on page 9
3. “Installing the Sense Voltage and Control Voltage Cables in Wye and Delta
Services” on page 11

Mounting the PowerLogic EM4000 meter
Figure 3 shows the general mounting layout for metering 120V/208V wye services,
and Figure 4 shows the general mounting layout for metering 347V/600V wye
services.
1. Remove the front cover from the meter by removing the four screws with a #2
Phillips screwdriver. Retain the cover and screws for later re-installation.
2. Mount the PowerLogic meter on the wall and secure it by inserting a screw in
each mounting keyhole and tightening the screws.
3. Mount the shorting block enclosure on the wall as shown in Figures 3 and 4.
Secure it by inserting a screw in each mounting keyhole and tightening the
screws.
4. Install the conduit for voltage and current connections.
In Figure 3, the meter is powered and takes its sense voltage directly from a
breaker within the panel.
