Installation Information
STEP 1: Check the rating and configuration of the meter label to ensure it is
suitable for the intended service. Class 4000 meters can only be used
in single-phase applications. Verify that the meter rating is suitable for
the intended load. Compare the color of the arrows on the current
sensors to the chart below to find the amperage of the sensors.
SENSOR ARROW COLOR CODE SENSOR RATING
BROWN - 100 AMP
RED - 200 AMP
STEP 2: Mount the meter in desired location using the four mounting holes
located inside the enclosure. Class 4000 meters must be installed
indoors, where they will not be affected by the elements.
STEP 3: Assemble and install current sensors around conductors to be
monitored. For each phase being monitored you will need one two-
piece current sensor assembly. Open the two-piece current sensor
assembly by releasing the nylon clamp using a flathead screwdriver.
Using a flathead screwdriver, press the tab on the nylon clamp to
open the current sensor assembly.
STEP 4: Reassemble the current sensor assemly around the conductor(s)
to be monitored. Be sure that 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.

Troubleshooting Guide
The Class 4000 electronic kilowatt-hour meter is caibrated and tested at the factory be-
fore being packaged and shipped. If installed properly and in accordance with the instal-
lation instructions, the Class 4000 meter will provide years of trouble-free service. If the
meter should not function, the following guide will assist in trouble shooting the instal-
lation. 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, or
is not incrementing.
. A. Determine if the load is sufficient to update the
display. (A load of less than 1% of the meter rating
may require more than 24 hours to change the
display reading.)
B. Check the current sensors for installation.
C. Be sure that the current and 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 sure that it is on
of the power consumption. continuously 24 hours a day.
B. Check the current sensors for installation and
polarity.
C. Check the sensor wiring to the terminal block in
the meter (color coding white to white and black to
black).
25% of rated voltage
The Class 4000 single-phase kilowatt-hour meters are used to monitor power to
individual loads after the utility company meter. Installation should be performed by
qualified personnel and ONLY according to these instructions and local electrical codes.
E-Mon and its representatives assume no responsibility for damage or injury resulting
from the improper installation of this meter.

NOTE: When the E-Mon D-Mon®meter is installed where the tenant has access to the
electrical panel powering the meter, it is suggested that a dedicated breaker NOT be
used to power the E-Mon D-Mon meter, because a dedicated breaker can be shut off.
If a dedicated breaker must be used, it should be a lockable style.
NOTE: Depending on the amount of power being used, a period of time will elapse
before the meter registers readings. In the case of light loading, this could be as
much as several hours.
