1 WARNINGS AND CAUTIONS
The following section contains installation and wiring instructions for the Leviton Mini Meter™.
If technical assistance is required at any point during the installation, contact information can
be found at the end of this manual. Leviton is not responsible for damage to the meter caused
by incorrect wiring, which will void the product’s warranty.

WARNING:
• TO AVOID FIRE, SHOCK OR DEATH; TURN OFF POWER at circuit breaker or fuse
and test that the power is off before installing product or servicing current transformers.
• TO AVOID FIRE, SHOCK OR DEATH; Look inside the meter and electrical panel for
possible exposed wire, broken wire, damaged components or loose connections.
• Make sure all tools used during installation have proper installation ratings.
• Installations should be done in accordance with local codes and current National
Electric Code requirements, and performed by trained, qualified professionals.
• Equipment used in a manner not specified by this document impairs the protection
provided by the equipment.
CAUTIONS:
• 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).
• Consult local codes for any possible permits or inspections required before beginning
electrical work.
• 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 INSTALLATION INSTRUCTIONS
4.1 Preparation
WARNINGS
•TO AVOID FIRE, SHOCK OR DEATH; TURN OFF POWER at circuit breaker
or fuse and test that power is off before installing product or servicing current
transformers.
•TO AVOID FIRE, SHOCK OR DEATH; Look inside the meter and electrical
panel for possible exposed wire, broken wire, damaged components or loose
connections.
•Specification for branch circuit protection, rated min. 250 V, 1A, for voltage
sense / input leads.
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
• Meter installations 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 enclosure be mounted near the disconnecting
device in an area with adequate ventilation.
•The enclosure 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 load center cannot be found, additional
in-line fuses or circuit breaker may be required in accordance with NEC
regulations.
