E-Mon 3208200W KIT - Manual (Page 5)

5.3.2 Current Sensor Wiring (continued)
NOTE: When the E-Mon D-Mon® Class 4000/4100 meter is installed where the
tenant has access to the electrical panel powering the meter, it is suggested that
a dedicated breaker NOT be used to power the meter, as a dedicated breaker
can be shut off and stop the meter from recording. If a dedicated breaker must
be used, it should be a lockable style.
5.4 Main Power
After the meter circuit wiring has been examined for correctness, power may be
applied to the circuit board. If the monitored circuit is under load, the LED in the
meter’s upper right hand corner will actively blink - indicating the amount of load
by the frequency of its pulse. A heavy load will blink faster than a light load. Very
light loads will result in an extended blink time.
6.0 Features & Operating Guide
The 6-digit display shows the
kilowatt-hours consumed by
the metered load.
The blinking LED indicator
provides a visual pulse signal
of the meter’s load. A heavier
load will increase the blink
frequency.
* The sealing tab provides the
meter with a location to install
a utility type security seal.
NOTE: Depending on the amount of power being used, a period of time will
elapse before the meter registers. In the case of light loading, this could be as
much as several hours.
6.1 RF Wireless Metering Option (Class 4100)
When the meter is ordered with the RF option (Class 4100), it will be provided
with a factory installed 900 mHz RF module for AMR (Automatic Meter
Reading.) This module is pre-wired to the meter and will be active when the
meter is powered.
This module is designed to be used with E-Mon Energy™ software and an
available RF Wireless Gateway for either on-site reading or through an internet
connection. The system requires factory start-up services. Contact E-Mon for
additional details.

1.1 Internal Electronic Assemblies
The unit is comprised of one or two subassembly boards, the meter board and
the optional RF board (Class 4100). Both circuit cards are mounted inside the
non-metallic enclosure.
Note: Units are suitable for indoor applications only.
Figure 1.1 Internal electronic assemblies.
1.1.1 Meter Board
Connections to this board include the MAINS input voltage and current
sensors. The MAINS input terminals (TB1) are covered with a protective clear
shield for safety purposes. The current sensor assemblies interface to two
header connections, TB2, and TB3. Each header connector input corresponds
to an input voltage phase; care must be exercised to ensure that each current
sensor is connected to the correct input header.
