The E-Mon D-Mon® Class 2000 kWh/Demand meter is a 3-element meter used to
monitor electric power usage of individual loads after the utility meter. Installation
must only be performed by qualified personnel and in accordance with these
instructions and all applicable local and national electrical codes. E-Mon or its
representatives assume no responsibility for damages or injury resulting from the
improper installation of this meter.
Meters are supplied in a UL Type 1 steel enclosure appropriate for indoor installation
where it will not be affected by the elements, such as moisture and extreme
temperatures.
Units designated by the “R” suffix on the model number have an extended
environmental operating range and are enclosed in a NEMA 4X enclosure to
accommodate outdoor environments.
Verify the input voltage rating and configuration on the meter label to ensure it is
suitable for the intended electrical services. For example, Class 2000 meters labeled
for 208V service MUST NOT be installed on service feeds of 480V and vice versa.
