3.8.2 Installation of Voltage Input Wires

1. Depending on the branch circuit, in-line fuses may be required by local

electrical codes.

2. Connect wiring for Line voltages and Neutral to the appropriate locations in the

breaker panel in accordance with all national and local electrical codes; see

Figure 4 for wiring diagram. Table 2 lists the voltage inputs.

3. The power source of the meter must be the same as the power source of the

load that the meter is measuring.

4. Trim the wire to the appropriate length to avoid coils of excess wiring.

5. Strip wiring to 0.3 inch if needed and connect to the appropriate terminals.

3.8.3 Installation of Current Transformers

General Requirements:

• If CT secondary wires are routed through conduit, splices on the CT leads

must be within the meter enclosure, not inside the conduit. Leviton-provided

CT lead wires are 48 inches long, 18 AWG.

• It is acceptable to route voltage input wires and CT secondary wires through

the same conduit as long as all the wiring in the conduit meets National

Electric Code requirements (at least 18 AWG). CTs should be securely

fastened such that they will not slide down to live terminals.

• Current and voltage inputs must be installed ‘in phase’ for correct readings.

As shown in Figure 6, CT1 needs to monitor the same phase as the voltage

connected to the meter on L1 and CT2 needs to monitor the same phase

as the voltage connected to the meter on L2. The CTs must be connected

between line and load, not on the voltage wires that lead to the meter.

• Be sure to install the CTs with the correct orientation (direction). If the meter

displays a Reverse Energy error after installation (see Table 7), it is likely that

you have either installed a CT backwards or have reversed the X1 and X2

terminal connections.

1. Strip wiring to 0.3 inch.

2. Trim the wire to the appropriate length to avoid coils of excess wiring.

3. Connect the CT leads to the appropriate terminals; see wiring diagrams

(Figure 6) for correct CT orientations and connections. A list of the CT

connections is given in Table 3.

4. For Split Core CTs:

Remove the thumb screws at the bottom side of the CT as shown in Figure 5

(left) and pull away one side of the CT to open it as shown in Figure 5 (right).

b. With power to the conductors turned off, place the CT around the

appropriate conductor while ensuring that the white labels (the side

facing up in the ﬁgure) faces Line (source).

c. Note the white mark on the removed section of the CT and make

sure to align it with the white mark on the CT case. (The white mark

is visible at the lower corner of the CT in Figure 5.) Close the CT by

sliding the removed section back into place and replacing the thumb

screws. For accuracy, it is very important to be sure the white marks

are aligned and the CT is completely closed with the screws installed.

d. Connect the CT wires to the meter inputs as described in Table 3.

e. Repeat for remaining conductor for two phase applications, as shown

in Figure 6.

For Solid Core CTs: With power turned off, disconnect each monitored

conductor one at a time and slide on appropriate CT, ensuring the CT is

correctly oriented as shown in Figure 6. Reconnect the conductors. Connect

the CT wires to the meter inputs as described in Table 3.

3 INSTALLATION INSTRUCTIONS

3.10 Testing the Installation

Verify Voltage:

Characters are always displayed on the LCD when the meter has proper power

on L1 and neutral (See Section 4.1 for a description of LCD screens).

Verify Energy:

Before checking energy direction, make sure there is a load drawing a minimum

of 1A connected to the meter.

The LCD has an energy-ﬂow indicator in the lower left section of the display. The

energy-ﬂow indicator points to the right when the meter measures positive energy

(normal) and points left when the meter measures negative energy.

If the arrow is not shown, points to the left or is shown with no pointer in either

direction, there is an installation problem. Refer to Section 6 for troubleshooting

instructions.

Verify Load:

The load LED has a 10Wh pulse rate (5 watt hours on, 5 watt hours off). The duty

cycle should be 50% when the meter is connected properly and a constant load

is applied. Figure 7 shows the appearance of the LCD when the meter is installed

properly.

WEB VERSION

4 GENERAL METERING FEATURES AND FUNCTIONALITY

4.1.1 Calculation of Maximum Demand

Maximum demand (kW) reports maximum consumed power for a 24-hour period

and is calculated using a 15-minute “sliding window” interval divided into three

5-minute sub-intervals, as follows:

• For dual-element meters, power measurements are combined values for Line

1 and Line 2.

• Power measurements are summed over the 5-minute sub-interval and

averaged at the end of the sub-interval.

• At the end of each sub-interval, demand for the three most recent sub-

intervals is averaged to give a new interval demand value.

• Over each 24-hour period the largest interval demand value for the period is

saved.

• During the ﬁrst 24 hours after the meter is powered up, the maximum

demand display shows the largest interval demand value calculated since

startup.

• After the ﬁrst 24 hours of operation, reported maximum demand is updated

only once every 24 hours and shows the largest interval demand for the

previous 24-hour period.

Note that 24-hour maximum demand periods are based on the meter’s runtime

since power up, not a real time clock.

4.1.2 Using the Display to Determine Meter Status

Table 7 explains how errors are indicated on the LCD. The table lists error

conditions in order of priority (highest priority ﬁrst). If more than one error

condition exists, the LCD error screen shows only the highest-priority error.

For installation errors, if the same error condition exists on both lines the LCD

error screen reports the error only for line 1, but both L1 and L2 symbols blink.
