277 VAC (L-N) 249 to 305 VAC
6.3 Phasing of Line Voltage
The 3-phase AC power input or single-phase option must be in proper phase
sequence. If the sequence is incorrect or a phase is missing, there will be a
message on the meter’s display: “PH Sequence Error” or “PH Missing:.” (Refer to
the section on Line Voltage Diagnostics if this message is present.) When the line
voltage is connected correctly, the meter’s display will be blank (no message.)
Wait for the meter display to scroll to the voltage display. Verify that the meter
reads correct voltages on all three phases. Repeat Step F.
Once the meter displays the correct line voltages and there are no error
messages, you are ready to connect the current sensors to the meter. Before
continuing with the installation, verify that the six screens display as follows:
Screen 1 (kWh): Should read 0.0 kWh; if not, should be reset.
Screen 2 (kW Peak Demand):kW peak should read 0.0 kW. There will not
be a date/time stamp yet. If there is a kW
peak recorded, it should be reset later
Screen 3 (kW Load): Should read 0.0 kW load.
Screen 4 (Amps per Phase): There should be 0.0 on all three phases.
Or in the SP option - 0.0 in A and B phases.
Screen 5 (Average AC Volts): See Step F.
Screen 6 (Average AC Volts):See Step F.
Screen 7 (Power Factor): There should be 0.0 PF on all three phases.
Or in the SP option - 0.0 in A and B phases.
NOTE: The meter will be reset later via the software during “startup” procedures.

6.4 Current Sensor Installation & Wiring
Once the AC voltages have been confirmed to be within acceptable limits, you are
ready to install the current sensors. TB1, positions 5 and 6 are the inputs for
Phase A, TB1 positions 7 and 8 are the inputs for Phase B and TB1 positions 9
and 10 are the Phase C inputs.
The Single-Phase option use TB1 pos 5&6 are A - TB1 pos 7&8 are B phase factory installed jumper wire on positions 9&10. Factory installed jumper should
not be removed.
The E-Mon Class 3400 Meter can be used with two types of 0-2V current sensors.
1. Split-core current sensor. This sensor opens so that it can be attached
around the circuit being monitored without interrupting power. Unless otherwise specified, all Class 3400 meters are supplied with this sensor type.
2. Solid-core current sensor. This sensor does not open and requires the mon-
itored conductor to be removed from the circuit to install the current sensor.
This type is only supplied when specified at time of order.
6.4.1 Installing the Split-Core Current Sensor Assembly
1. Each phase being monitored will require one two-piece current sensor
assembly. Open the two-piece current sensor assembly by releasing the
nylon clamp using a flathead screwdriver.
Fig. 5. Split Core Sensor.
2. Reassemble the current sensor assembly around the conductor(s) to be
monitored. Ensure the current sensor halves marked “Load” are both facing
the load side of the conductor. The colored arrow will be on the source side
of the conductor being monitored and MUST be pointed in a clockwise
direction around the conductor being monitored. Tighten the nylon clamp
to complete the assembly.
Fig. 6. Split Core Sensor.
17 62-0398—02
E-MON CLASS 3400 METER
IMPORTANT:
When looking from the source side of the conductor(s) being monitored,
you should see the arrow on the current sensor assembly. The arrow
should be pointing in a clockwise direction around the conductor(s) being
monitored. If the arrow is not positioned on the source side, inaccurate
readings will result.
6.4.2 Current Sensor Wiring
Once the current sensors are installed onto their appropriate phase conductors,
you can begin terminating the current sensors onto the E-Mon Class 3400 Meter
main board. The current sensors can be extended up to 500 feet for remote
monitoring applications. To extend the length of the wires, use #22 AWG twistedpair wire with one white and one black wire.
The easiest way to connect the current sensors is to use the meter’s built-in
current sensor diagnostics. To do this, there must be at least 1% of the meter’s
current rating (amps) flowing in each of the conductors being monitored. The EMon Class 3400 Meter’s diagnostic program will provide data to ensure that the
current sensor installation is done properly.
The current sensor connection points are located at the bottom right of the main
power board. These are terminals 5 through 10 of terminal block TB1. Each
sensor connects to two terminals one labeled “Black” and the other “White.”
Current sensors should be connected to the meter one at a time and verified
using the current sensor diagnostic program.
Connect one of the current sensors to TB1 terminals 5 and 6 (Phase A). Wait 5
seconds and look at the meter display.
If the meter displays an error message (see below), remove the wires from
terminals 5 and 6 and install them on terminals 7 and 8 (Phase B). if an error
message occurs with the sensor attached to terminals 7 and 8, try again on
terminals 9 and 10 (Phase C).
The “CT Error:“msage will disappear when the current sensor is connected to the
correct terminals (phase).
Error Messages: CT ERROR: A
CT ERROR: A B
CT ERROR: A C
NOTE: The Single-Phase option will only display errors for A and B.
Refer to the section on Current Sensor Diagnostics for assistance in
troubleshooting these errors.
6.4.3 Main Power
After the meter circuit wiring has been examined for correctness, power may be
applied to the circuit board. There are three LEDs located in the upper right
corner of the Meter Board labeled BEAT, STATUS and LOAD. The BEAT and
STATUS LEDs will blink once per second when the meter is operating normally,
62-0398—02 18
E-MON CLASS 3400 METER
twice per second if there is a problem.If the monitored circuit is under load the
LOAD LED will actively blink. A heavy load will cause the LED to blink faster than
a light load. Very light loads will result in an extended blink time.
