2.3 Display Specifications
2.3.1 General Display Information
Series 1000 and 2000 meters provide active energy measurements, which are
displayed on the LCD in 1 kWh resolution. These values are cumulative and are
cannot be reset. When configured with the energy demand option, the meters provide
instantaneous readings on the integrated LCD. These values are displayed one at a
time, for six seconds each, as follows:
• Total Active Energy, in kWh (1 kWh resolution, cumulative, non-resettable)
• Instantaneous Demand, in Kilowatts (last 5 minute average, 1/100 kW resolution)
• Peak Demand: Kilowatts (15 minute rolling demand interval, 1/100 kW resolution
A dot in the LCD aligns with an arrow on the display label to differentiate between
instantaneous and peak demand. After displaying peak demand and before displaying
total energy, the meter tests the LCD by activating all segments simultaneously for
one second.
2.3.2 Resetting the Peak Demand (optional additional feature)
An additional optional feature is the Peak Demand reset. Meters configured with the
Peak Demand Reset option have an integrated key switch which is used to reset the
peak demand. A demand reset command will only be recognized during the period
when the peak demand is displayed on the LCD. In order to reset the demand, a
pulse must be generated by turning the key switch from locked position (arrow up)
to the right and then back to the original position. This back and forth transition
triggers a demand reset. The maximum transition period is one second. Multiple key
switch transitions during the peak demand display interval may be required to reset
peak demand.

Figure 4 - Mounting the Enclosure
3.5.2 Conduit Openings
Steel Enclosure
The Series 1000 and 2000 steel enclosure comes with a 1 1/16” knockout (3/4”
conduit) on the bottom of the enclosure, and a 7/8” knockout (1/2” conduit) on
top of the enclosure. To remove a knockout, use a flathead screwdriver (or other
rigid device) to puncture the indentations first, and then pry off and discard the
knockout.
Outdoor Enclosure
The bottom panel and lower half of the side panels work best for conduit opening
locations in outdoor single meter enclosures. Select the location that makes wire
installation easiest for the given environment. If the side panels are used, holes
should be centered approximately half an inch from the bottom of the enclosure.
Hole sizes must be appropriate to fittings, and large enough to fit all voltage and
CT wiring (4-10 18 AWG min. wires insulated for 600 V min.). Care should be
exercised to keep drill bit away from components inside the enclosure. UL Type
4X conduit and fittings must be used in order to maintain the outdoor rating
of the enclosure.
3.5.3 Mounting Procedure and Conduit Installation
1. For outdoor enclosures, attach the mounting brackets to the back of the
enclosure with the four provided screws as shown in Figure 4.
2. Fasten the enclosure to the selected surface using the provided mounting holes
(steel enclosure) or mounting brackets (plastic enclosure).
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).

3.7 Installation of Current Transformers
General Requirements:
• Splices on the CT leads must be within the meter enclosure, not inside the conduit.
Leviton CTs come with standard 48inch leads. 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
over-tighten, as this may compress and weaken the conductor.
• Current and voltage inputs must be installed ‘in phase’ for accurate readings (e.g.
CT1 on Line 1, CT2 on Line 2) Orientation is critical. Ensure that all CTs are
properly oriented with the line and load, as marked.
TO AVOID FIRE, SHOCK OR DEATH, always open or disconnect the circuit
from the power distribution system of a building before installing or servicing
current transformers.
In accordance with NEC, CTs may not be installed in any panel board where
they exceed 75% of the wiring space of any cross-sectional area.
