1 WARNINGS AND CAUTIONS

The following section contains installation and wiring instructions for the Leviton Mini Meter

in indoor Surface Mount enclosure. 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.

• Like repeaters, MDTs should not be mounted inside a metal box or near a metal wall

(i.e. heating furnace or electrical panel). Consult the Tehama QuickStart Guide, which

can be downloaded from the manufacturers website.

• MDTs must be mounted using velcro, tie-wraps, or screws. Don’t let the MDT

dangle by the pulse input wire.

• Avoid locations with dampness, high humidity, or an abundance of mold.

• 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.

2.5 Physical Description

2.5.1 Mini Meter in Surface Mount Enclosure

2.5.2 Tamper Protection

Two ﬂat-head screws that secure the enclosure front may be covered with

adhesive-type security seals that indicate tampering when removed. Also, some

models provide a tamper indication through the wireless AMR system when

enclosure cover is removed.

2.6 Functional Description

The 6PSMT and MMSMT versions of the Mini Meter accurately quantiﬁes electrical

energy usage of 1PH 3W (2-pole) 120/208V or 120/240V loads. Solid Core Current

Transformers are used to measure current ﬂowing to a load. Energy information

(pulses) is recorded by the onboard wireless transceiver, which time stamps kWh

readings in 15-minute intervals and sends it over a secure wireless network to a Data

Concentrating Access Point (DCAP), where data from a network of meters is stored

for on a local computer for billing or energy management functions, or data can be

pushed from the DCAP or pulled from remote locations via an ethernet connection.

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.

CAUTIONS

•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.

•Speciﬁcation for branch circuit protection, rated min. 250 V, 1A, for voltage

sense / input leads.

4.2 List of Materials

•Mini Meter, Surface Mount enclosure and associated mounting materials, four

#6 x 15/8 drywall screws.

•Additional wiring for CT or voltage leads extension if needed. Wires must be 18

AWG or thicker and insulated for 300 VAC min.

•Current Transformers (CTs): This product is designed for use with Leviton CTs

• Flexible, non-metallic conduit and ﬁttings; UL Type 4X for outdoor applications.

4.3 Setting up the Enclosure

4.3.1 Mounting Location

•Mini Meter surface mount enclosures 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 Mini Meter.

•It is recommended that the enclosure be mounted near the disconnecting

device in an area with adequate ventilation.

•Ensure that the CT and voltage lead lengths (and conduit lengths) are capable

of reaching the enclosure from the load center.

•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.
