Installing Potential Transformers for Three-Phase Service Greater
Than 277V
Potential transformers are required when metering services greater than the rated
voltage input of the meter. Potential transformers are used to reduce the
line-to-neutral voltage of the service to 120V. The accuracy class should be 0.3%
or better, with a burden rating of 30VA.
For applications in Canada, Measurement Canada approved potential transformers
are required. Measurement Canada requires an accuracy class of 0.3% or better,
with a 150VA rating.
NOTE: Potential transformer burden depends on the control voltage source. If
control voltage is provided separately (not derived from the metered voltage), then
lower transformer burden may be acceptable. Contact your local Schneider Electric
representative for details.
Mount the potential transformer enclosure between the supply voltage and the

The sense voltage (A, B, C, N) provides phase voltages for metering. The
configuration depends on the type of service being metered:
•
•
•
•
•
The PowerLogic EM4033 and EM4080 meters are shipped from the factory with a
control voltage jumper that can be used to connect the control voltage input and the
sense voltage inputs to provide control voltage to the unit. The following procedures
explain how to connect the sense voltage inputs for each of the service types.

The PowerLogic meters must be connected to the sense voltage and control
voltage through a properly rated disconnect that disconnects all line and neutral
wires, so it can be powered down. The disconnect must be located within easy
reach of the meter operator, and must be labeled as such. Opening the disconnect
or breaker is the disconnect device. For multiple PowerLogic meter installations,
the same disconnect can be used to power all meters, and must be labeled for all
meters it supplies power to. The disconnect device must meet IEC 60947-1, IEC
60947-3 and/or comply with the local electrical code.

Delta service metering
To use the PowerLogic EM4000 meter in a Delta service, the line-to-line voltage
from the Delta service must be reduced to 120V line-to-line using appropriate
potential transformers. Metering a Delta service requires only two potential
transformers, and only two CTs for phase A and C.
For a three-phase Delta panel with the 120V variant of the meter:
•
•
•
•
Connect meter terminal A to the voltage disconnect phase A (red wire)

Installing the Current Transformers
The two models of PowerLogic EM4000 meter use current transformers (CTs) with
different secondary outputs. The PowerLogic EM4033 meter uses split-core 0.333V
CT wiring is required (up to 300 feet [91.44 meters]). The PowerLogic EM4080
meter can also use a 5A CT if a 5A converter has first been installed.
For instructions, see “Installing the CTs on the PowerLogic EM4033 and
Current transformers connect to the PowerLogic EM4033 and PowerLogic EM4080
meters through the 50-conductor CT cable provided with the meter. Table 2
describes the CT wire pairs and the cable color scheme for each meter point. You
can also find this information on the inside of the meter’s outer cover.
Each CT has an X1 (positive) and X2 (neutral) wire pair and uses butt-splice
connectors to attach the CT to a specific meter wire pair. The direction of the
energy flow is indicated on the CT by: a label (“This side towards source”); an arrow
that points away from the source; or a stamp/label indicating which side is H1 (H1
side faces toward the source).
CT shorting blocks are recommended for all CT installations. CTs measuring live
current must either be connected to the PowerLogic meter via the 25-pair CT cable,
or the secondary output of the CTs must be shorted together. Open-circuit CTs
may generate a hazardous voltage and could damage equipment or cause
personal injury.

Connecting the Communications
Connections for communications using the Ethernet port or Modbus RTU port are
described in this section.
Connecting the Ethernet Cable
If the Ethernet port is used to report data, an RJ45 patch cable is required to
connect the Ethernet port to the local Ethernet network.
1. Route the cable through the slot in the PowerLogic EM4000 meter enclosure.
2. If the local network automatically assigns IP addresses through a DHCP server,
the PowerLogic EM4000 meter will be able to report using its factory default IP
settings. If the local network is configured for static IP addresses, refer to the
PowerLogic EM4000 meter Configuration Guide for instructions on how to
configure default static IP addresses.
Connecting the Modbus RTU Communications
If the Modbus port is used to report data, an RS422/RS485 serial cable is required
to connect the Modbus RTU port to the local Modbus network.
1. Route the cable through the slot in the PowerLogic EM4000 meter enclosure.

Connecting Pulse Inputs
Each PowerLogic meter has two pulse inputs that can be used to count and report
pulses generated by another meter (pulsing device).
Connect the output of the pulsing device to one of the two pulse input terminal
negative terminal pin on the right, and a positive terminal pin on the left. The pulse
inputs are compatible with both dry and solid-state form A contacts, 10 Hz
(maximum), 20 ms pulse width (minimum).
When the pulsing device provides dry relay contacts, the PowerLogic meter pulse
inputs are not polarity-sensitive. When the pulsing device provides solid-state
form A outputs, the negative terminal from the source device must be connected to
the negative terminal of the PowerLogic meter pulse in terminal block.
The pulsing device can be located up to 1,000 feet away from the PowerLogic
meter with 22 AWG twisted pair wire.
Start-Up Sequence
Use the following procedure to start up the PowerLogic EM4000 meter.
1. Ensure that all CT and sense voltage wiring is securely installed.
2. Remove all tools from the work area.
3. Re-install all cover plates and equipment covers.
4. Power up the meter. The LCD on the front panel of the meter indicates the
operating status of the unit as follows:
a.
b.
Initial power up message “PowerLogic EM4000”
After the internal configuration is complete, the display shows default information
for the first meter.
Manually Testing Communications
This procedure clears the meter memory, manually tests the communications from
the PowerLogic EM4000 meter, and updates the meter clock. To force the meter to
send data, follow these steps:
1. Press and hold the Display button for 5 to 7 seconds until the diagnostics mode
is displayed, then release.
2. If communicating via Ethernet, press the Display button until "Local IP Address"
appears on the display.
a.
If the IP address is 169.254.0.10, the meter has not found a DHCP server. As a
result, the meter will use its default IP configuration and may not be able to report.
See the PowerLogic EM4000 meter Configuration Guide for instructions on how to
program default IP addresses.
b.
If the IP address is not 169.254.0.10, the meter has acquired an IP address from
the local network, and will be able to report data and synchronize time.
3. Press the Display button until the “Send” command appears on the display.
4. Press the left or right arrow button to manually force the PowerLogic EM4000
meter to report metering data using the Ethernet or modem connection. This
clears data from the PowerLogic EM4000 meter memory, and ensures the time
is set correctly.
