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
