1.0 INTRODUCTION

The E-Mon D-Mon® Class 3200 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. 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. Class 3200 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 3200 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.
