4 INSTALLATION INSTRUCTIONS
4.1 Preparation
1. Verify the model number and electrical specifications of the device being
installed to confirm they are appropriate for the intended electrical service (see
Section 3).
2. Consult local codes for any possible permits or inspections required before
beginning electrical work.
3. Ensure the conduit for the installation is flexible and non-metallic. For outdoor
applications conduit and conduit fittings must be rated UL Type 4X for outdoor
enclosures. Failure to use the appropriate conduit impairs the degree of
equipment protection.
4. Make sure all tools to be used during installation have proper insulation
ratings.
5. Look inside the MMU and electrical panel for possible exposed wire, broken
wire, damaged components or loose connections.
4.2 List of Materials
• Mini Meter MMU and associated mounting materials.
Line 1, Line 2, and Neutral hook-up wires as needed for the electrical service.
Wires must be 18 AWG or larger and insulated for 300 VAC min
(NOT INCLUDED).
Current Transformers (CTs): This product is designed for use with Leviton CTs;
see Section 3.2 for details (NOT INCLUDED IN ALL MODELS).
Flexible, non-metallic conduit and fittings; UL Type 4X for outdoor applications
(NOT INCLUDED).
4.3 Mounting the Enclosure
4.3.1 Mounting Location
• MMUs require a switch or circuit breaker as part of the building installation.
The switch or circuit breaker must be marked as the disconnecting device for
the MMU.
It is recommended that the MMU be mounted near the disconnecting device in
an area with adequate ventilation.
The MMU should not be positioned in a manner that makes it difficult to operate
the disconnecting device.
Ensure that the CT and voltage lead lengths (and conduit lengths) are capable
of reaching the enclosure from the breaker panel.
If a suitable mounting location near the panel cannot be found, additional inline
fuses or circuit breaker may be required in accordance with NEC regulations.

4 INSTALLATION INSTRUCTIONS
4.3.2 Drilling Conduit Holes
Please refer to the figure below for drilling conduit openings.
Conduit hole sizes must be appropriate to fittings. Care should be exercised to
keep drill bit away from components inside the MMU. For large (19" x 15" x 8")
and extra-large (29" x 21" x 10") enclosures conduit holes should be located so
as not to interfere with the installation of wires or viewing of meters. UL Type 4X
conduit and fittings must be used in order to maintain the outdoor rating of
the enclosure.

4.3.3 Mounting Procedure and Conduit Installation
1. Attach the mounting brackets to the back of the enclosure with the four
provided screws as shown in Figure 6.
2. Fasten the enclosure to the selected surface via mounting holes.
3. Verify that the enclosure is not loose and that all connections are secure.
4. Attach the conduit between enclosure and load center, routing wires as
necessary for later use.
5. Make sure the conduit fittings are aligned properly and tightened securely to
prevent moisture from entering the enclosure (outdoor applications).
4.4 Installation of Voltage Lines
WARNING: TO AVOID FIRE, SHOCK OR DEATH, ensure service is disconnected
before any connections are made. Verify that branch circuit fuse specifications
meet local electric codes (see section 3.2).
For Small and Medium Enclosures
1. Field wired voltage connections are made to the Mini Meter terminal block. The
rated torque for these terminal blocks is 4.4 in-lb, and can be used with solid and
stranded copper wires, at 12-18 AWG.
2. Connect 300 V min. insulated wiring for Line voltages and Neutral to the
appropriate locations in the breaker panel, in accordance with all national and
local electrical codes; see Figure 10 for 1Ph, 2-wire applications; Figure 11 for 1 or
2 Ph, 3-wire applications; Figure 12 for 3 Ph, 4-wire applications.
3. Route wires through the conduit if not already done.
4. Trim the wire to the appropriate length to avoid coils of excess wiring.
5. For connections to the Mini Meter terminal, strip wiring to approximately .300
inches and connect to the appropriate terminals. Wires should be tightened so that
they are held snuggly in place, but do not to over-tighten, as this may compress
and weaken the conductor.

4.5 Variations and Installation of Current Transformers
General Requirements
Leviton provided CT leads are 48 inches minimum. Wire insulation should be
stripped so that the bare conductor length that connects to the meter terminal
block does not exceed 0.300 inches.
CTs should be securely fastened such that they will not slide down to live
terminals.
Wires should be tightened so that they are held snuggly in place, but do not to
overtighten, as this may compress and weaken the conductor.
For 1 or 2 Ph 3-Wire electrical panels, current and voltage inputs must be
installed "in phase" for accurate readings (e.g. CT1 on Line 1, CT2 on Line 2);
see Figure 11.
For 3 Ph 4-wire electrical panels, see Figure 12 and follow factory-provided
meter schedules for correct CT locations.
CT Variations
Leviton solid core CTs (Figure 8): In accordance with CT label, the LINE side
of CT must face incoming Line. White lead connects to X2 of CT connection
(CT1:X2 or CT2:X2). Black or red (solid or striped) lead connects to X1 of the
corresponding CT connection (CT1:X1 or CT2:X1).
Installing solid core CTs
1. Route CT wires through the conduit if not already done.
2. Trim the wire to the appropriate length to avoid coils of excess wiring.
3. At MMU, strip insulation from wires to approximately .300 inches.
4. Connect CT leads to the appropriate meter as described above.
5. With power turned off, disconnect each monitored conductor and slide
on a CT, ensuring the CT is correctly oriented as noted above.
6. Reconnect the conductors.

4 INSTALLATION INSTRUCTIONS
4.5 Variations and Installation of Current Transformers
Leviton split core CTs (Figure 9): The side with the white dot, H1, must face the
incoming LINE. White wire connects to X2 terminal, black wire connects to X1
terminal.
Installing split core CTs
1. Route CT wires through conduit if not already done.
2. Trim the wire to the appropriate length to avoid coils of excess wiring.
3. Strip wiring to approximately .300 inches.
4. Connect the CT leads to the appropriate meter as described above.
5. With power to the conductors turned off, place one CT around each
conductor, ensuring that the white dot is facing the line side.
Failure to install CTs in the correct orientation will lead to inaccurate meter
readings. Figure 10 through Figure 12 show wiring diagrams for the various
voltage configurations.

Testing Voltage
The LCD will turn on when the Mini Meter has the proper power supply. Voltage
should also be tested using an AC Voltmeter to verify that the voltage across
voltage line terminals (L1 to Neutral and L2 to Neutral) is not in excess of the
maximum rated voltage in section 3.2.
CT Reverse Phase Indicator
Reverse phase is indicated on the LCD in the lower left corner of the display.
If an arrow is displayed, power down the voltage supply and verify that all CTs
are installed correctly.
Load LED
The load LED is described in section 3.3. This LED should be cycling at 50% duty
cycle when the meter is connected properly and a sufficient load is applied.
4.7 Securing the Enclosure
In accordance with safety requirements, MMUs must be secured using the
provided key lock once installation is complete. The purpose of the lock is to
prevent access to live parts that pose potential safety risks. To install the lock,
slide through the provided holes on the clamp side of the enclosure and fasten
securely.
Properly installed meters with sound connections and secure conduit fittings should not
require user maintenance. If the meter is functioning abnormally, consult the Troubleshooting/
FAQ guide. If the answer cannot be found there, contact Technical Support.
