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

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.

• Look at the meter and inside the electrical panel for possible exposed wire, broken

wire, damaged components or loose connections.

3.4 List of Materials

• Series 1000 or Series 2000 meter, enclosure, and associated mounting materials

• Line 1, Line 2, Line 3 and Neutral hookup wires, as needed for the electrical

service

• Wires must be 18 AWG or larger and insulated for 600 VAC min. Meter terminals

will accept wiring up to 14 AWG.

• Current Transformers (CTs): This product is designed for use with Leviton 100mA

series of solid and split core CTs.

• Conduit and ﬁttings, as appropriate. UL Type 4X conduit and ﬁttings must be used

for outdoor applications to maintain the rating of the installation.

3.5 Mounting the Enclosure

3.5.1 Selecting a Mounting Location

• Series 1000 and 2000 meters 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.

• 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 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.

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).

Figure 5: Leviton Solid Core CTs

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 48-inch 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

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.
