1 WARNINGS AND CAUTIONS
The following section contains installation and wiring instructions for the Leviton wireless
meter in an indoor flush 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.
• Make sure all tools used during installation have proper installation ratings.
• Installations must 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 Meter in Flush Mount Enclosure
2.6 Functional Description
The MDTFW version of the meter accurately quantifies electrical energy usage of 1PH
2W or 2PH 3W 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.
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
•Meter, flush mount enclosure and associated mounting materials, two #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 Mounting the Enclosure
4.3.1 Mounting Location
•Meters with flush 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 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.
