1.0 INTRODUCTION
The E-Mon D-Mon® Class 3400 meter is a 3-element meter with communications. The
device is used to monitor electric power usage of individual loads after the utility meter
and store kW and kVAR data for automatic meter reading. The Class 3400 meter is
dual protocol capable and provides both RS485 and Ethernet communications.
Installation must only be performed by qualified personnel and in accordance with
these instructions and all applicable local and national electrical codes. E-Mon and its
representatives assume no responsibility for damages or injury resulting from the
improper installation of this meter.
Verify the input voltage rating and configuration on the unit panel label to ensure that it
is suitable for the intended electrical service. 3400 meters labeled for 120/208V service
MUST NOT be installed on service feeds of 277/480 volts or 347/600 and vice versa.
Verify that the Class 3400 meter’s current sensors are sized suitably for the load to be
monitored. Compare the color of the arrows on the current sensors to the chart below
to confirm the correct current sensor is being used.

CAUTION
Internal circuit card components are extremely sensitive to electrostatic
discharge. Prior to handling or touching internal circuitry, discharge any
static buildup on your person. To discharge yourself, touch a grounded
metal object such as conduit or an earth grounded metal enclosure.
WARNING
Use of this instrument, the E-Mon D-Mon Class 3400, in a manner
inconsistent with this manual or not specified by the manufacturer in
writing, can cause permanent damage to the unit and/or serious injury to
the operator. The protection and safety features provided by this
equipment may become impaired or otherwise compromised.
NOTE: If any trouble arises during installation or functional verification opera-
tions, do not immediately remove unit. Before removing the unit, con-
tact E-Mon’s technical support department at (800) 334-3666. E-Mon’s
technical department will assist you in detailed troubleshooting of the
Class 3400 installation and assist you in getting the unit operating cor-
rectly.
2.0 INTERNAL ELECTRONIC ASSEMBLIES
The units are comprised of two major subassembly boards, the main power board and
the display board. Both circuit boards are mounted inside a NEMA 4X enclosure.

2.1 Main Power Board
Connections to this board include the MAIN Power Input and current sensors.The
MAIN Power Input terminals are positions one through four on the four position screw
terminal block, TB1. These terminals are covered with a protective shield for safety
purposes. The current sensor assemblies interface to the TB1 positions 6 thru 10; care
must be exercised to ensure that each current sensor is connected to the correct
terminals. One three terminal screw connector (RS485) is for RS-485 communications.
One two terminal screw connection (output) is for a pulse output. One RJ-45 jack (J8)
is provided for 10/100-baseT Ethernet.
Fig. 2. Main Power Board Connections.
2.1 Main Power Board
When ordered, header J3 is 20 positions for use with an I/O board with up to two
relays, two pulse inputs and two pulse out puts. Meters ordered with the X (Expanded
Feature) package have the I/O board pre installed.

2.2 Display Board
The display board connects to the main power board via a flex ribbon cable and the
board mounts on the inside of the housing door.No additional connections to the
display board are required. The display board’s LCD readout indicates the metered
values as well as errors associated with the Class 3400 meters, such as phase loss or
sensor error conditions.
