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.
