2.0 PRECAUTIONARY AND SAFETY
INFORMATION
CAUTION
Internal circuit card components are extremely sensitive to
electrostatic discharge. Be careful not to touch internal circuitry prior
to discharging any static buildup on your person. To discharge yourself,
touch a grounded metal object such as conduit or an earth-grounded
metal enclosure.
CAUTION
High voltages present on main PCB terminal block TB1 screw
terminals. Risk of serious injury and/or electrical shock exists. Prior to
performing any wiring operations, review all contents of the user
manual and de-energize the MAINS power switch. Only qualified
personnel should perform installation wiring. Installation wiring must
comply with all local and national electrical codes.
CAUTION
Failure to ground the enclosure creates a possible shock hazard. Do not
operate the MMU Style Meter without a protective earth wire attached
securely to the PE terminal screw. After installing protective earth
wiring, secure the screw tightly (7 N-m torque.)
CAUTION
NEVER open front panel of unit while unit has MAINS power applied.
Failure to comply can increase the risk of serious injury and/or
electrical shock.

3.0 INTRODUCTION TO MULTIPLE METER
UNITS (MMU)
3.1 Application
This Install Manual describes a line of Multiple Meter Units (MMU) used in
monitoring electrical usage in commercial, industrial, or institutional facilities.
Voltage and current are continuously measured and updated to provide highly
accurate, true RMS power information via current sensors.
3.2 General Description
The MMU allows for compact installation of multiple meters that allows for easy
and centralized reading. A single MMU cabinet can be configured to contain up
to 8, 16, or 24 meters of different voltage configurations (i.e. 208V and 480V).
Fig. 1. MMU 8 Cabinet.

4.0 DESCRIPTION OF MULTIPLE METER
UNITS (MMU)
MMU cabinets can be used to house Class 1000, Class 2000, Class 3200 and
Green Class meters. IDR’s, (Interval Data Recorders) can also be installed in the
MMU cabinets with the meters.
These units are briefly described below:
4.1 Class 1000/2000 Meters
The Class 1000 and Class 2000 meters are power meters for use in sub metering
applications. The devices take inputs from current sensors and the line voltage
and output kW hours in pulses.
Refer to Sections 5, 6, &7 for general installation instructions on installing Class
1000 or Class 2000 meters into a MMU Cabinet.
4.2 Class 3200 Meters
The Class 3200 meter is a 3-element meter with communication. The device is
used to monitor electric power usage after the utility meter and store kW and
kVAR data for automatic meter reading.
Refer to Sections 5, 6, &7 for general installation instructions on installing Class
3200 meters into a MMU Cabinet.
4.3 Green Class Meters
The Green Class Meter is a power meter for use in sub metering applications. The
devices take inputs from current sensors and the line voltage and output kW
hours in pulses.
Refer to Sections 5, 6, &7 for general installation instructions on installing Class
3200 meters into a MMU Cabinet.
4.4 IDR (Interval Data Recorders)
The Interval Data Recorder (IDR) is an energy data collection device with
communication. The device is used to count digital pulses of the utility meter and
store data for automatic meter reading. Various communications types are
provided, EZ7, Modbus RTU, Modbus TCP/IP, BACnet MS/TP, BACnet IP, and
Lonworks TP/FT-10.
Refer to Sections 5, 6, &7 for general installation instructions on installing IDR
meters into a MMU Cabinet.

5.0 MMU CABINET INSTALLATION
5.1 MMU Cabinet Description
The MMU Cabinet is made from 14 or 16 gauge steel. The cabinet has an ANSI 61
gray exterior finish. It contains a seam that is continuously welded and ground
smooth. The heavy gauge continuous hinge pin that connects the door and the
enclosure body are removable. There are screw-down clamps located on the door
for easy locking of the cabinet.
Fig. 2. Cabinet Dimensions.
5.2 MMU Cabinet Installation
The dimensions of the MMU8, MMU16, and MMU 24 cabinet are shown in Figure
2.
The MMU cabinet shall be mounted in an upright orientation as shown in Figure
3. The MMU cabinet must only be installed by personnel with the proper electrical
licensing for the intended location.
Use appropriately sized mounting hardware to fasten the MMU enclosure to the
selected mounting surface. The four housing mounting holes are located on the
upper and lower mounting brackets.
Serviceability/field Repair Service and repair should be completed by qualified
personnel only. Meters cannot be calibrated in the field. Adjustment is limited to
reset of the meter display and should be performed by qualified personnel only.
The configuration is stated on each meter nameplate.

The MMU enclosure is not supplied with knockouts. The installer will make the
necessary entrances to the enclosure to supply entry for the voltage and current
sensor conductors. The conduit and fittings must be appropriate for the
application and installed in a manner to meet national and local electrical codes.
Spaces not occupied by meters will have a blank metal cover over the display
window.

6.0 MMU CABINET WIRING
6.1 General Wiring Instructions
Wiring of the individual MMU meters are the same as for a stand-alone meter.
See section 7.0.
Refer to the Individual Meter Installation Manual for individual meter wiring.
Fig. 4. MMU Terminal.
Some MMU units may come from the factory already pre-wired for the voltage to
the installed meters. When supplied this way, there will be a terminal block
located inside the MMU that is labeled A, B, C, N. See Figure 4. The letters refer to
the three phases and neutral connections already made to the meters. The power
only has to be landed on the terminal block in order to power all of the meters in
the MMU.
As with the stand-alone meters, the power wires must be fused. The size of the
fuse will be determined by the number of meters installed in the MMU. The
Littelfuse KLDR series are used for this component. Each meter point requires 1/
10 amp fusing. With 8 meters, a one amp fuse would be acceptable.
The current sensor wiring is installed by bringing in the leads from their source
and landing them on the appropriate terminals on the meter’s sensor input
terminals.

The proper current sensor wiring to each meter is described in each individual
Meter Installation Manual.The MMU style meters are wired the same way, but it is
important that proper routing procedures are followed when the current sensor
conductors are installed.
a. The sensor leads cannot be installed randomly and should be bundled
together when they are routed to the meters which are mounted on the
door of the MMU. They shall be secured and routed away from the power
wiring and the communication cabling. They shall be bundled with
appropriate means such as clamps, wire ties, spiral wrap, etc.
b. To avoid damage to the bundled conductors when the door is opened
and closed, tubing, guides, spiral wrap, clamps, or other approved
means shall be used. This is required to provide proper protection and
stress relief for the conductors.
c. All wiring is to be routed away from any points that may possibly dam-
age or abrade the insulation - such as sharp edges, screw threads,
burrs, or any other item that may have been installed in the MMU enclo-
sure. The final wiring must allow the door to freely open and close with-
out coming in contact with anything that could damage it.
NOTE: Following the proper wiring procedures will help to assure a satisfactory
installation.
NOTE: Units housed in UL type 1 enclosures must only be installed in indoor
locations, where they will not be affected by the elements
6.2 Grounding
The meters and enclosure must be
properly grounded for safety. A protec-
tive earth ground lug is provided for
this purpose.
Failure to ground the enclosure creates
a possible shock hazard. There are two
terminals that attach to the base
ground stud.
Do not operate without protective
earth wire attached securely to the PE
terminal screw. After installing the
protective earth wiring, secure the
screw tightly (7 N-m torque).
Fig. 5. Base Ground Stud.

HONEYWELL E-MON® MMU-STYLE METERS
62-0417—02 12
6.3 RS485 Communication Wiring
The RS485 Communication wiring is installed by connecting the leads to the
appropriate terminals on the 3-position RS485 terminal strip mounted on the
back panel of the enclosure. The wiring terminals are labeled GND, HIGH, and
LOW to correspond to the appropriate connections of the communication
cabling. Tighten the terminals to 9 in-lbs of torque. Class 1 rated, Belden 1120A
cable (600V) is to be used for communication wiring in MMU enclosures. The
communication cabling must be routed away from the mains wiring.
