1.0 INTRODUCTION
The Honeywell E-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. Honeywell 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 E-Mon 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.
