Installation ProceduresThis section provides information about activities that must be performed to
install the PowerLogic EM4833, EM4880 and EM4805 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 EM4800 meter” on page 9
2.“Installing Potential Transformers for Three-Phase Service Greater
Than 277V” on page 11
3.“Installing the Sense Voltage and Control Voltage Cables in Wye and
Delta Services” on page 13
4.“Installing the Current Transformers” on page 21
5.“Connecting the Communications” on page 30
a.“Connecting the Phone Line” on page 30
b.“Connecting the Ethernet Cable” on page 30
c.“Manually Testing Communications” on page 30
Mounting the PowerLogic EM4800 meter Figure 4 shows the general mounting layout for metering 120V/208V wye
services, and Figure 5 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 4
and 5. 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 4, the meter is powered and takes its sense voltage directly from a
breaker within the panel.
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 PowerLogic meters as shown in Figure 5. Transformer configuration
must be Y||Y (wye-wye).
In Figure 5, the meter is powered from the potential transformers that are fed
from a breaker within the 600Y/347V panel. The CT cable is connected to the
shorting enclosure before connecting to the CTs in the panel.
Installing the Sense Voltage and Control
Voltage Cables in Wye and Delta Services
The sense voltage (A, B, C, N) provides phase voltages for metering. The
configuration depends on the type of service being metered:
•see “For a single-phase panel with the 120V variant of the meter:” on
page 15
•see “For a 208Y/120V three-phase wye panel with the 120V variant of
the meter:” on page 16
•see “For a 416Y/240V (or 380Y/220V) three-phase wye panel with the
230/240V variant of the meter:” on page 17
•see “For a 480Y/277V three-phase wye panel with the 120V variant of
the meter:” on page 18
•see “For a 600Y/347V or higher three-phase wye panel with potential
transformers with the 120V variant of the meter:” on page 19
•see “For a three-phase Delta panel with the 120V variant of the meter:”
on page 20
The PowerLogic EM4833, EM4880 and EM4805 meters are shipped from
the factory with a control voltage jumper that can be used to 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.
For a single-phase panel, use a 3-wire (red, black, white), 14 AWG
(1.63 mm
black, blue, white), 14 AWG (1.63 mm2), 90°C (194°F) cable. For a Delta
service, use a 3-wire (red, black, blue), 14 AWG (1.63 mm
2
), 90°C (194°F) cable. For a three-phase panel, use a 4-wire (red,
2
), 90°C (194°F)
cable. Metallic, flexible armored cable (BX cable) is recommended for
commercial installations as shown in Figure 6 on page 15.
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.
To install the control voltage cable in a 208Y/120V or 120/240V application:
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

•Replace all devices, doors and covers before turning on power to
this equipment.
•The meters must be connected to the sense voltage and control
voltage through a properly rated voltage disconnect (not shown in
the wiring diagrams).
Failure to follow these instructions will result in death or serious
injury.
NOTE: If the circuit breaker panel does not designate phase A,
phase B and phase C feeds, make your own designation and use it for
the rest of the installation.
1.Before connecting the sense voltages, turn off the power to the circuit
being connected.
2.Always use a properly rated voltage sensing device to confirm power is
off.
3.Connect the sense voltages phase A, B, C, and N leads from the
voltage disconnect to the meter as described in Figure 6 on page 15
and Figure 7 on page 16.
NOTE: The phase wiring sequence A, B, C between the PowerLogic
EM4800 meter and the panel must match or the measurement
readings will be wrong.
4.If more than one meter is being installed, repeat this procedure for each
additional meter.
For a single-phase panel with the 120V variant of the meter:
•Connect meter terminal A to the voltage disconnect phase A (red wire)
•Connect meter terminal B to the voltage disconnect phase B (black
wire)
•Connect meter neutral terminal to neutral bar in the voltage disconnect
panel (white wire)
•Connect earth wire to earth post using lug provided
•Meter terminal C is not connected
•Install power supply shorting jumpers (see Figure 6)
The PowerLogic EM4833, EM4880 and EM4805 meters are rated for direct
input of 120V to 277V 60Hz phase potential. When metering services greater
than 120V, the meter is powered from a separate 120V instrument
transformer. Figure 9 shows the wiring of the control voltage transformer for
a service between 240V and 277V.

Delta service metering
To use the PowerLogic EM4800 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. Using the
phase B CT is optional.
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)
•Connect meter terminal C to the voltage disconnect phase C (blue wire)
•Connect meter neutral terminal to meter terminal B (black wire)
•Connect earth wire to earth post using lug provided (see Figure 11)
Figure 11: PowerLogic EM4800 meter three-phase Delta service
connection
Installing the Current TransformersThe three models of PowerLogic EM4800 meter use current transformers
(CTs) with different secondary outputs. The PowerLogic EM4833 meter uses
split-core 0.333V CTs (see Figure 12), and the PowerLogic EM4880 meter
uses 80mA CTs only (see Figure 13) and is typically used where accuracy is
important and long secondary CT wiring is required (up to 300 feet [91.44
meters]). The PowerLogic EM4880 meter can also use a 5A CT if a 5A
converter has first been installed.
For instructions, see “Installing the CTs on the PowerLogic EM4833 and
PowerLogic EM4880” on page 22, and “Installing 5A Converters and CTs on
the PowerLogic EM4880” on page 23.
The PowerLogic EM4805 uses 5A secondary CTs. For instructions, see
“Installing the 5A CTs on the PowerLogic EM4805” on page 27.
Current transformers connect to the PowerLogic EM4833 and PowerLogic
EM4880 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.
Figure 12: PowerLogic EM4833 split-core 0.333V current transformer
1.Connect the 50-pin connector to the PowerLogic connector located at
the bottom side of the unit, and secure it in place with the retaining clips.
2.Feed the free end of the cable through the bottom left of the meter
enclosure.
This cable is made up of twisted-pair wires for connecting the individual
CTs to the metered points. The color codes for the X1 (positive) and X2
(neutral) connections for each CT are listed in Table 2 on page 26.
NOTE: The direction of the energy flow is indicated on the CT.
3.Turn off the power feed to the panel where the CTs are being installed.
Always use a properly rated voltage sensing device to confirm power is
off.
4.Feed the CT cable into the panel through an appropriate punch-out with
an approved strain relief.
5.Strip the plastic sheaths on the cable to an appropriate length to expose
the wire pairs. Cut and strip the CT leads and wire pair leads to an
appropriate length. Crimp the CT leads to the wire pairs for each meter
point.
6.Connect the X1 lead of the CT to the X1 lead of the cable, then connect
the X2 lead of the CT to the X2 lead of the cable (see Table 2).
7.When using solid-core CTs, remove the feed wire from the circuit
breaker, place the CT over the wire, and reconnect to the circuit
breaker. Ensure that the arrow on the CT label is pointing in the
direction of the energy flow (toward the load).
8.When using split-core CTs, separate the halves of the CT and place the
CT over the wire to the circuit breaker. Ensure that the CT is facing the
source as shown on the label. Install cable ties to ensure that the CT
halves are held together securely.
9.Repeat steps 5 to 8 for the remaining CTs.
Installing 5A Converters and CTs on the PowerLogic EM4880
When both low-current (200A and 400A) and high-current (600A or higher)
circuits need to be measured with the same PowerLogic meter, converters
are available to allow the use of Measurement Canada approved 5A CTs
with the appropriate current rating. 5A CT converters transform the 5A
maximum output from a standard CT to the 80mA maximum of the
PowerLogic meter.
The 5A side of the converter is the black and red wire pair, and the 80mA side
of the converter is the black and white wire pair.
NOTE: It is recommended that 5A converters and shorting devices be
installed in a sealable metal enclosure.
To connect the 5A CT to the converter on the PowerLogic EM4880, follow
these steps:

connect the Ethernet port to the local Ethernet network.
1.Route the cable through the slot in the PowerLogic EM4800 meter
enclosure.
2.If the local network automatically assigns IP addresses through a
DHCP server, the PowerLogic EM4800 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 EM4800 meter
Configuration Guide for instructions on how to configure default static
IP addresses.
Start-Up SequenceUse the following procedure to start up the PowerLogic EM4800 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.Initial power up message “PowerLogic EM48xx”
b.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 EM4800 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
EM4800 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
EM4800 meter to report metering data using the Ethernet or modem
connection. This clears data from the PowerLogic EM4800 meter
memory, and ensures the time is set correctl y.
Pulse InputsThere are two pulse in terminal blocks in the PowerLogic meter, as shown in
Figure 15. Each terminal block has a 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). The inputs are not polarity-sensitive to dry relay contacts. 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.
Display NavigationThe PowerLogic EM4800 meter has three buttons to control the information
presented on the LCD. The display has a normal and a diagnostics mode.
The PowerLogic EM4800 meter starts in normal mode, and enters
diagnostics mode when the Display button is pressed and held for 5 seconds.
To adjust the contrast, hold down the Display button, and use the right and
left arrow buttons to increase and decrease the contrast respectively.
Normal Mode
In Normal mode, the Display button scrolls through the information for each
meter. The left and right arrow buttons select the previous or next meter
points respectively. The following information is available:
•Real Energy Delivered kWh D
•Real Energy Received kWh R
•Real Power Watts
•Reactive Energy Delivered KVarhD
•Reactive Energy Received KVarhR
•Reactive Power Var
In Normal mode, the right and left arrow buttons scroll the display from meter
points 1 to 8, 1 to 12, or 1 to 24, depending on your configuration.
Diagnostics Mode
Diagnostics mode is accessed by pressing and holding the Display button for
5 seconds. In Diagnostics mode, pressing the Display button will scroll
through the following additional information:
In Diagnostics mode, the right and left arrow buttons scroll the display from
meter 1 to 8, 1 to 12, or 1 to 24, depending on your configuration. When the
local IP address is shown on the LCD, use the right and left arrow buttons to
scroll through the following information:
•Remote host server IP address
•Time server IP address
•Default IP address
•Default NetMask
•Default gateway
•PPP user name
•Phone number
•AT command string
•Alternate phone number
•Unit serial number
•Firmware build number
