GREEN CLASS METER
5 62-0340-01
The Honeywell Green Class meter is a single, dual or 3-ele-
ment meter used to monitor electric power usage of individual
loads after the utility meter. Installation must only be per-
formed by qualified personnel and in accordance with these
instructions and all applicable local and national electrical
codes. Honeywell or its representatives assume no responsi-
bility for damages or injury resulting from the improper instal-
lation of this meter.
Units designed by the “R” suffix on the model number have
an extended environmental operating range and are enclosed
in a NEMA 4X housing to accomodate outdoor environments.
Verify the input voltage rating and configuration on the
meter label to ensure it is suitable for the intended electrical
services. Class 200 meters labeled for 120/208V service
MUST NOT be installed on service feeds of 277/480V and
vice versa.
Verify the 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 sen-
sor is being used.

CAUTION: Internal circuit card components are ex-
tremely 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 in a manner inconsis-
tent with this manual or not specified by the manufac-
turer 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.
PRE-INSTALLATION
INFORMATION
Internal Electronic Assemblies
The unit is comprised of two major subassembly boards,
Main Power Board and Display Board. All circuit cards are
mounted inside a NEMA 12 (standard) or NEMA 4X (optional)
enclosure.

DISPLAY BOARD
NOTE: Units are supplied in a NEMA 12 metal enclosure
suitable for indoor applications only. Units supplied in the
optional NEMA 4X fiberglass enclosure are suitable for either
indoor or outdoor applications, within the defined specifica-
tions. Refer to Section 12.0 for a definition of suitable envi-
ronmental conditions for indoor and outdoor units.
Main Power Board
Connections to this board include the MAINS Input Voltage,
Current Sensors, external IDR interface and Isolated Pulse
Output.
The MAINS input terminals are covered with a protective
clear shield for safety purposes. The current sensor assem-
blies interface to either TB1 (standard configuration) or to
three header connectors, TB2, TB3 and TB4 (ST configura-
tion). Each header connector input corresponds to an input
voltage phase, so care must be taken to ensure each current
sensor is connected to the correct input header.
