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:

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.
