1.0 INTRODUCTION
The E-Mon D-Mon® Class 3200 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. 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. Class 3200 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 3200 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 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 enclosure.
WARNING
Use of this instrument, the E-Mon D-Mon Class 3200 meter, 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 the installation or functional verification opera-
tions, do not immediately remove the unit. Before removing the unit, contact
E-Mon’s technical support and/or engineering department at (800) 334-3666.

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 UL Type 1 or Type 4X
enclosure.
Fig. 1. Internal Electronic Assemblies.
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 TB2, TB3 and TB4. Each
terminal block corresponds to an input voltage phase; care must be exercised to
ensure that each current sensor is connected to the correct terminal block. One three
terminal screw connector is provided for RS-485 communications.

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.
The Class 3200 meter features a 4-line LCD display that indicates multiple meter data
points.
