1.0 INTRODUCTION
The Honeywell Green Class Net meter is a 3-phase 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 Green Class Net 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 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. For example, Green Class Net meters
labeled for 120/208V service MUST NOT be installed on service feeds of 277/480 volts
or 347/600 and vice versa (see chart below):
Verify that the Green Class Net 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.

CAUTION
Internal circuit card components are extremely sensitive to electrostatic
discharge. Prior to handling or touching internal circuitry, discharge any static
buildup on your person. To discharge yourself, touch a grounded metal object
such as conduit or an earth grounded metal enclosure.
WARNING
Use of this instrument, Green Class Net meter, in a manner inconsistent with
this manual or not specified by the manufacturer in writing, can cause
permanent damage to the unit and/or serious injury to the operator. The
protection and safety features provided by this equipment may become
impaired or otherwise compromised.

2.0 INTERNAL ELECTRONIC ASSEMBLIES
The unit is comprised of two major subassembly boards, the main power board and
the display board. Both circuit boards are mounted inside either a JIC STEEL
Enclosure.

2.1 Main Power Board
Connections to this board include the MAIN Power Input and current sensors. The
MAIN Power Input terminals are positions one through four on the four position screw
terminal block, TB1. These terminals are covered with a protective shield for safety
purposes. The current sensor assemblies interface to the TB2, TB3 and TB4. Each
terminal block corresponds to an input voltage phase; care must be exercised to
ensure that each current sensor is connected to the correct terminal block. One three
terminal screw connector(TB42) is provided for RS-485 communications. One RJ-45
jack (J8) is provided for 10/100-base T Ethernet. One two terminal screw connector
provides phase loss alarming.

2.2 Display Board
The display board connects to the main power board via a flex ribbon cable and the
board mounts on the inside of the housing door.
No additional connections to the display board are required. The display board’s LCD
readout indicates the metered values as well as errors associated with the Green
Class Net meter, such as phase loss or sensor error conditions.

2.3 Input Board
The Green Class Net meter is supplied with an input board which allows it to accept
pulses (dry contact) from third party meters, such as gas, water, BTU, etc. This 3rd
party meter information that comes in through the pulse input can be communicated
via the communication protocols. Only one input is available with EZ7 PROTOCOL.
Fig. 4. Input Board.
The input terminals and output terminals are used by the Green Class Net meter.
Connect metering devices with “dry contacts” only. If the contacts are from solid - state
(electronic) sources, polarity must be observed for proper operation.
