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.
