3.6 Installation of Voltage Lines
Check to ensure service is disconnected before any connections are
made. Verify if additional in line fuses are required based on National
and Local electrical codes.
1. The Series 3300/3500 meter is compatible with both 3-phase 3-wire (no-neutral) and 3-
phase 4-wire systems. The meter derives power from the Line 1 and Line 2 voltage
connections, which must be between 177 and 552V for the meter to work properly. Field
wired voltage connections are made to the Series 3300/3500 voltage terminal block. The
rated torque for these terminal blocks is 12 in-lb., and can be used with 14 AWG solid or
stranded copper wires.
2. Connect 600 V min. insulated wiring for Line voltages and Neutral to the appropriate
locations in the breaker panel, in accordance with all national and local electrical codes;
see Hookup Diagrams in Figures 8 –11 below for correct wiring information.
3. Route wires through the conduit if not already done.
4. Trim the wire to the appropriate length to avoid coils of excess wiring.
5. Connect additional in line fuses if required.
6. For connections to the Series 3300/3500 pulse outputs: Route wiring through the top of
the enclosure. Strip wiring to approximately .300 inches and connect to the appropriate

Revision 0.9

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.
3.7 Variations and Installation of Current Transformers
To reduce risk of electric shock, 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.
General Requirements:
Splices on the CT leads must be within the meter enclosure, not inside the conduit.
Leviton provided CT leads are 48 inches minimum. 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. Maximum rated torque for CT
terminal blocks is 4.4 in-lb.
Current and voltage inputs must be installed ‗in phase‘ (e.g. CT1 on Line 1, CT2 on Line
2, CT3 on Line 3) and oriented correctly as shown in Hookup Diagrams in Figures 8
through 11.

CT Installation Procedures
1. Route CT secondary wires through conduit if not already done.
2. Trim the wire to the appropriate length to avoid coils of excess wiring.
3. Strip wiring to approximately .300 inches.
4. Connect the CT leads to the appropriate terminals; see Hookup Diagrams in
figures 8 through 11 below for correct CT orientations and connections. The
CT terminal block is removable to make wire connections easier; see Figure 5.
After securing CT wires to the appropriate terminals slide terminal block up
into header until fully seated.
6. For Split Core CTs: Remove two thumb nuts (Figure 6) and remove section
from CT. With power to the conductors turned off, place the 3-sided section
of the CT around the appropriate conductor while ensuring that white label,
white dot or H1 faces Line (source). Reassemble the CT while ensuring that
the white hash marks align (figure 5) and reinstall thumb nuts. Repeat for
remaining conductors for two or three phase applications, as shown in Figures
8 through 11.
7. 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 Figures 8 through 11. Reconnect the
conductors.

3.8 Securing the Enclosure
The outdoor enclosure ships with a padlock and key for securing the door after
installation is complete. The indoor enclosure has a captive screw for securing the
enclosure door.
3.9 Turning Power On and Checking for Correct Functionality
1. After installation is completed and enclosure has been secured the meter may be
energized at the disconnect switch, upon which the meter will go through a power up
sequence as described in Section 4.3. It is strongly advised that users of this product
read Section 4 below for a complete description of meter functionality and displayed
values.
2. Several diagnostic tools built into the Series 3300/3500 meter that should be utilized to
ensure the meter and CTs are installed correctly and functioning properly:
a. Energy Flow arrow –Indicates direction of ‗energy flow‘ on amperage and kW
screens.
b. For mono-directional metering applications the Energy Flow arrow should always
point to the right. If an Amperage or kW screen shows the arrow pointing to the
left a current transformer may be installed backwards or on the wrong phase, or
CT connections at the meter may be reversed or connected to the wrong CT input
terminals, or voltage wires at the meter could be cross-phased. Section 4 further
describes how the Amperage screens operate to indicate a reverse energy

condition. Refer to Hookup Diagrams in Figures 8 through 11 for correct wiring
and CT orientations.
c. Power Factor Screens –Except in rare circumstances where predominantly
inductive loads are metered, Power Factor values should have an absolute value
greater than 0.6. A lower value indicates CTs installed on the wrong phase,
backwards, or incorrectly connected at the meter, or voltage connections at the
meter could be cross-phased. If PF is lower than 0.6 recheck CT placements and
orientations and CT and voltage connections at the meter against the appropriate
Hookup Diagram shown in Figures 8 through 11.
3. Bi-directional metering is typically used in grid-tied applications in which solar PV or
energy from a source other than the utility grid is fed into the metered service. CTs are
located between the grid and the electrical service so that if the locally generated energy
exceeds the service loads, the grid will receive energy instead of delivering it. The Series
3300/3500 meter indicates energy direction with the Energy Flow arrow and blinking
Amperage and phase indicator icons on the Amperage and kW screens.
4. General Metering Features and Functionality

Phase Indicators and Parameter Indicators
The Phase and Parameter Indicator sections have two purposes. The Phase Indicators show the
phase currently being displayed on per-phase values. Parameter Indicators are associated with
values on the main numerical display.
Low Voltage
Low voltage (below minimum rated voltage with respect to neutral) on a phase is shown
by a blinking of the ‗V‘ Parameter Indicator in conjunction with corresponding Phase
Indicator. For example, if low voltage is detected on phase A the ‗V‘ Parameter Indicator
and the ‗A‘ phase indicator will blink simultaneously.
Energy Flow Indicator
On all Amps and kW screens the Energy Flow arrow will illuminate indicating energy
direction. Arrow pointing to the right indicates energy delivered (from grid for grid-tied
meters in renewable energy applications); arrow pointing to the left indicates energy
received (to the grid). In addition to the arrow, the Amps parameter indicator (―A‖) and
the corresponding phase indicator (A, B, or C) flash when Energy Flow arrow points left.
When meter is installed in a mono-directional metering application, the Amps and
kW arrows should always point to the right when load current is present.
