1.0 Introduction
The E-Mon D-Mon Class 4000/4100 meter is a 1 or 2-element meter with
optional RF wireless communications (Class 4100). The device is used to moni-
tor electric power usage of individual loads after the utility meter and display kWh
consumption on a direct reading digital display. With the Class 4100 wireless RF
option, it will provide kWh and kW data for automatic meter reading. Installation
must only be performed by qualifi ed 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 confi guration on the unit panel label to ensure
that it is suitable for the intended electrical service. Class 4000/4100 meters
labeled for 120/208V service MUST NOT be installed on service feeds of
277/480 volts.
Verify that the Class 4000/4100 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 confi rm the correct 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 metal
enclosure.
WARNING: Use of this instrument, the E-Mon D-Mon Class 4000/4100
meter, in a manner inconsistent with this manual or not
specifi ed 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 troubles arise during the installation or functional
verifi cation operations, do not immediately remove the unit.
Before removing the unit, contact E-Mon’s technical support
and/or engineering department at [phone]. E-Mon’s
technical department will assist you in detailed troubleshooting
of the Class 4000/4100 meter installation and assist you in

7.0 Troubleshooting Guide
The Class 4000/4100 electronic kilowatt-hour meter is calibrated and tested
at the factory before being packaged and shipped. If installed properly and in
accordance with these installation instructions, the Class 4000/4100 meter will
provide years of trouble-free service. If the meter should not function, the fol-
lowing guide will assist in troubleshooting the installation. If, after following the
procedures below, the meter still does not function, please call E-Mon’s technical
department at [phone] BEFORE removing the meter.
Problem Procedure to follow
1. Display reads all ZEROs, A. Determine if the load is suffi cient
or is not incrementing. to update the display (A load of
less than 1% of the meter rating
may require 24 hours to change
the display reading.
B. Check the current sensor
installation.
C. Be sure that the current &
voltage inputs have proper
phase relationship.
D. Check wiring to voltage
terminals.
E. Check circuit breaker or fuses.
F. Test source for correct voltage.
2. Display reads only a fraction A. Check the supply voltage to be
of the power consumed. sure that it is on 24 hours a day.
B. Check the current sensors for
installation and polarity.
C. Check the current sensor to
verify that it is the correct amp
rating.
D. Check the sensor wiring to the
terminal block in the meter
(verify color coding white-to-
white and black-to-black.)
