1 Precautions
1.1 Only qualified personnel or licensed electri-
cians should install the WattNode meter. The
mains voltages of 120 to 600 Vac can be lethal!
1.2 Follow all applicable local and national electri-
cal and safety codes.
1.3 The terminal block screws are not insulated.
Do not contact metal tools to the screw termi-
nals if the circuit is live!
1.4 Verify that circuit voltages and currents are
within the proper range for the meter model.
1.5 Use only UL listed or UL recognized current
transformers (CTs) with built-in burden resis-
tors, that generate 0.333 Vac (333 millivolts AC)
at rated current. Do not use current output
(ratio) CTs such as 1 amp or 5 amp output
CTs: they will destroy the meter and may
create a shock hazard.
1.6 Protect the line voltage inputs to the meter with
fuses or circuit breakers (not needed for the
neutral or ground wires). See 3.3.1 below.
1.7 Equipment must be disconnected from the
HAZARDOUS LIVE voltages before access.
1.8 If the meter is not installed correctly, the safety
protections may be impaired.

Connect the line voltages to the meter inputs as shown in the following figures
for each service type. See Figure 1 above for an overview.
2.2.1 Single-Phase Two-Wire with Neutral

2.2.2 Single-Phase Two-Wire No Neutral
This circuit occurs in residential (commonly 120/240 Vac) and some commercial
applications. The meter is powered from the ØAand ØBterminals. We recom-
mend connecting the Nterminal to ground to provide a clean voltage reference
for the measurement circuitry (no current will flow through this terminal).

service may be four-wire, wye but the load may only be three wire (no neutral).
Occasionally, a load will only be connected to two of the three lines (say L1 and
L2). For this case, connect the two active lines to the ØAand ØBterminals and
connect two CTs for the two lines.

2.2.6 Three-Phase Four-Wire Delta with Neutral (Wild Leg)
The uncommon four-wire delta electrical service is a three-phase delta service
with a center-tap on one of the transformer windings to create a neutral for
single-phase loads.
The high-leg or phase with the higher voltage as measured to neutral has tra-
ditionally been designated “Phase B”. A change to the 2008 NEC now allows
the high leg of a four-wire three-phase delta service to be labeled as the “C”
phase instead of the “B” phase. The WattNode meter will work correctly with
the high-leg connected to ØA, ØB, or ØC.

2.2.7 Grounded Leg Service
In rare cases with delta services or single-phase two-wire services without
neutral, one of the phases may be grounded.
The WattNode meter will correctly measure services with a grounded leg, but
the measured voltage and power for the grounded phase will be zero and the
status LEDs (if present) will not light for the grounded phase, because the volt-
age is near zero. Also, this type of service may result in unusual power factors.
See the web article Grounded Leg Services for more information.
3 Installation
3.1 Installation Checklist
See the sections referenced below for installation details.
□Mount the WattNode meter (see 3.2).
□Turn off power before making line voltage connections.
□Connect circuit breakers or fuses and disconnects (see 3.3.1).
□Connect the line voltage wires to the meter’s green terminal block (see
3.3.2).
□Mount the CTs around the line conductors. Make sure the CTs face the
source (see 3.4).
□Connect the twisted white and black wires from the CTs to the black
terminal block on the meter, matching the wire colors to the white and
black dots on the meter label (see 3.4.1).
□Check that the CT phases match the line voltage phases (see 3.4).
□Record the CT rated current for each meter, because it will be required
during commissioning.
□Connect the output terminals of the WattNode meter to the monitoring
equipment (see 3.5).
□Check that all the wires are securely installed in the terminal blocks by
tugging on each wire.
□Apply power to the meter.
□Verify that the LED indicates correct operation (see 4.2).
3.2 Mounting
●Protect the meter from temperatures below –30°C (-22°F) or above 55°C
(131°F), excessive moisture, dust, salt spray, or other contamination, using
a NEMA rated enclosure if necessary. The meter requires an environment
no worse than pollution degree 2 (normally only non-conductive pollution;
occasionally, a temporary conductivity caused by condensation).
●The meter must be installed in an electrical service panel, an enclosure,
or a limited access electrical room.
●Do not use the meter as a drilling guide; the drill chuck can damage the
screw terminals and metal shavings may fall into the connectors.
The meter has two mounting holes spaced 136.6 mm (5.375 in) apart (center-
to-center). These mounting holes are normally obscured by the detachable
screw terminals. Remove the screw terminals to mark the hole positions and
mount the meter.
Self-tapping #8 sheetmetalscrewsareincluded.Don’tover-tightenthescrews,
as long-term stress on the case can cause cracking.

3.3 Connect Voltage Terminals
3.3.1 Circuit Protection
The WattNode meter is considered “permanently connected equipment” and
requires a disconnect means (circuit breaker, switch, or disconnect) and over-
current protection (fuse or circuit breaker).
The meter only draws 10-30 milliamps, so the rating of any switches, discon-
nects, fuses, and/or circuit breakers is determined by the wire gauge, the mains
voltage, and the current interrupting rating required.
●The switch, disconnect, or circuit breaker must be as close as practicable
to the meter and must be easy to operate.
●Use circuit breakers or fuses rated for 20 amps or less.
●Use ganged circuit breakers when monitoring more than one line voltage.
●The circuit breakers or fuses must protect the mains terminals labeled
ØA, ØB, and ØC. If neutral is also protected, then the overcurrent protec-
tion device must interrupt both neutral and the ungrounded conductors
simultaneously.
●The circuit protection / disconnect system must meet IEC 60947-1 and IEC
60947-3, as well as all national and local electrical codes.
3.3.2 Line Wiring
● Always disconnect power before connecting the line voltage inputs to
the meter.
● For the line voltage wires, CCS recommends 16 to 12 AWG stranded wire,
type THHN, MTW, or THWN, 600 V.
●Do not place more than one voltage wire in a screw terminal; use separate
wire nuts or terminal blocks if needed.
● Verify that the line voltages match the line-to-line Ø-Ø and line-to-neutral
Ø-Nvalues printed in the white box on the front label.
Connect each line voltage to the appropriate phase; also connect ground and
neutral (if applicable). The neutral connection “N“ is not required on delta mod-
els (3D-240, 3D-400, and 3D-480), but we recommend connecting it to ground
if neutral is not present.
The screw terminals handle wire up to 12 AWG. Connect each voltage line to
the green terminal block as shown in Figure 1 above. After the voltage lines
have been connected, make sure both terminal blocks are fully seated in the
meter.
When power is first applied, check that the LEDs behave normally: on models
with status LEDs, if you see them flashing red-green-red-green (see Figure 7),
the line voltage is too high for this model, so disconnect the power immediately!
3.3.3 Grounding
The WattNode uses a plastic enclosure, insulation, and internal isolation bar-
riers instead of protective earthing. The ground terminal on the green screw
terminal block is a functional ground, designed to improve the measurement
accuracy and noise immunity. If necessary, this terminal may be left discon-
nected on wye models (-3Y).
3.4 Connect Current Transformers
To meet the UL listing requirements, the WattNode meter may only be used
with the following UL listed or UL recognized voltage output current transformer
models. These all generate 333.33 millivolts AC at rated current. See the cur-
rent transformer datasheets for CT ratings.

CTT-0500-xxx CTT-0750-xxx CTT-1000-xxx
CTT-1250-xxx
●“xxx” indicates the full scale current rating.
●“www” and “hhh” indicate the width and height in inches.
●“dddd” indicates the opening diameter of the loop for flexible Rogowski
CTs.
See the web article Selecting Current Transformers for information on se-
lecting appropriate current transformers (CTs).
●Do not use ratio or current output CTs such as 1 amp or 5 amp output
models!
●See the CT datasheets for the maximum input current ratings.
●Be careful to match the CTs with the voltage phases. Make sure the ØA CT
is measuring the current on the same phase being monitored by ØA, and
the same for phases B and C. Use the supplied colored labels or colored
tape to identify the CT leads.
●To minimize current measurement noise, avoid extending the CT wires,
especially in noisy environments. If it is necessary to extend the wires, use
twisted pair wire 22 to 14 AWG, rated for 300 V or 600 V (not less than the
service voltage) and shielded if possible.
●Find the source arrow or label “THIS SIDE TOWARD SOURCE” on the CT
and face/point toward the source of current.
●OPTIONAL: if you see spurious readings on unused phases, jumper the
unused CT inputs: for each unused CT, connect a short wire from the
terminal marked with a white dot to the terminal marked with a black dot.
To install the CTs, pass the conductor to be measured through the CT and con-
nect the CT leads to the meter. Always remove power before disconnecting
any live conductors. Put the line conductors through the CTs as shown in
Figure 1 above.
CTs are directional. If they are mounted backwards or with their white and black
wires swapped the measured power will be negative.
Split-core CTs can be opened for installation around a conductor. A nylon cable
tie may be secured around the CT to prevent inadvertent opening.
3.4.1 CT Wiring
Connect the white and black CT wires to the meter terminals marked ØA CT,
ØB CT , and ØC CT (see Figure 1 above). Excess length may be trimmed from
the wires if desired. The current transformers connect to the six position black
screw terminal block. Connect each CT with the white wire aligned with the
white dot on the label, and the black wire aligned with the black dot. Note the
order in which the phases are connected, as the line voltage phases must
match the current phases for accurate power measurement.
3.5 Connect the Output Signals
●The meter outputs are isolated from dangerous voltages, so you can con-
nect them at any time.
●If the output wiring is near line voltage wiring, use wires or cables with a
300 V or 600 V rating (not less than the service voltage).
●If the output wiring is near bare conductors, it should be double insulated
or jacketed.
●You may install two wires into each screw terminal by twisting the wires to-
gether, inserting them into terminal, and securely tightening. Note: a loose
wire can disable an entire network section.
●Use twisted-pair cable (unshielded or shielded) to prevent interference.
3.5.1 LonWorks FT-10 Network Wiring
CCS recommends that an experienced LonWorks network installer be con-
sulted for network design, particularly for the areas of topology, repeaters,
wiring, and termination. See the Operating and Reference Guide for more
details on LonWorks networks.
●The meter’s FT10 outputs are completely isolated from all dangerous volt-
ages, so you can connect them at any time with the meter powered.
●Connect the network wiring to the two circuit black terminal block labeled
FT10 and tighten the screws. The FT-10 twisted pair network is not polar-
ized, so either network wire can be connected to either screw terminal.
●FT-10 wiring may be daisy-chained between meters, with up to 127 devices
per subnet. The protocol has limits on the total wire length as well as stub
lengths, so see LonWorks FT-10 documentation for details and recom-
mended cabling.

●Once the meter is connected to the network and power is applied, configure
it on the LonWorks network using any of the following:
●Enter the meter information into the network management software and
press the service pin (button) on the meter when prompted. The service
pin is located on the side of the case to the left of the service LED.

●Record the meter’s Neuron ID and enter into the network management
software.
●Scan the network for unconfigured devices.
4 Operation
4.1 Initial Configuration
Generally, the network integrator will remotely configure the WattNode meter
and the variables. For details on configuring the WattNode meter, see the ap-
propriate Operating and Reference Guide for your model.
At a minimum, the CtAmps must be programmed with the rated amps of the
attached current transformers for accurate measurements.
4.2 LonWorks Service LED
The LonWorks service LED indicates the network configuration status of the
WattNode. The LED should always light while the service button (on the side
of the case below the LED) is being pressed: this can test that the WattNode
is powered.
Many problems can be diagnosed by observing the service LED. The figures
below shows the different behaviors of the WattNode service LED after power
up. During normal operation, after the initial power up and network configura-
tion, the LED should remain OFF. During some network management actions,
the service LED may light or flash until the action is complete. The following
terms describe the various states of the WattNode.
4.2.1 Unconfigured
Red Off
1.0 sec
1.0 sec1.0 sec
Red
The WattNode is operating properly, but has not yet been configured (installed)
by network management software. The LED will flash continuously.
4.2.2 Configured
Red Off
The WattNode is operating properly and has been configured by network man-
agement software. The LED will flash briefly when power is first applied, but
otherwise will stay off unless you press the service button.
4.2.3 Internal Error
Red
A solid red LED indicates that the WattNode meter is not functioning correctly
and must be returned for service.
4.2.4 Other
Any other LED pattern may be an internal error, indicating the WattNode needs
to be serviced. Before returning the WattNode, try cycling power and carefully
observing the LED. If possible, note the LED behavior, as this will help with
diagnostics.
4.3 Monitoring
The meter does not include a display or buttons, so it is not possible to oper-
ate the meter directly. The following is a brief overview of the possible remote
monitoring.
The LonWorks models communicate measurements over the various types
of networks. The measurements include: energy, power, voltage, current, line
frequency, power factor, reactive power, and demand.
In order to monitor and configure networked WattNode models, you will need
an appropriate monitoring solution, either standalone or PC software.
See the Operating and Reference Guide for a complete list of network ac-
cessible variables.
4.4 Maintenance and Repair
The WattNode meter requires no maintenance. It is not user serviceable and
there are no replaceable parts except the pluggable screw terminals and the
battery on Logger models. There are no diagnostic tests that can be performed
by the user, other than checking for errors via the communications interface
or the service LED.
In the event of any failure, the meter must be returned for service (contact CCS
for an RMA). For a new installation, follow the diagnostic and troubleshooting
instructions in the Operating and Reference Guide before returning the meter
for service, to ensure that the problem is not connection related.
The WattNode meter should not normally need to be cleaned, but if cleaning
is desired, power must be disconnected first and a dry or damp cloth or brush
should be used.
4.4.1 WattNode Logger Battery Replacement
The WattNode Logger for LonWorks meter contains a lithium battery to main-
tain the date and time during power failures. This battery can be replaced by
the user. See the Operating and Reference Guide for details.
●Replace battery with Panasonic, part number BR2325 only. Use of another
battery may present a risk of fire or explosion.
5 Specifications
The following is a list of basic specifications. For extended specifications, see

for measuring wye circuits. In the absence of neutral, voltages are measured
with respect to ground. Delta WattNode models use the phase A and phase
B connections for power.
Over-Voltage Limit: 125% of nominal Vac. Extended over-voltage operation
can damage the WattNode and void the warranty.
Over-Current Limit: 120% of rated current. Exceeding 120% of rated cur-
rent will not harm the WattNode meter but the current and power will not be
measured accurately.
Maximum Surge: 4kV according to EN 61000-4-5
Power Consumption: The following tables shows maximum volt-amperes,
the power supply ranges, typical power consumption, and typical power fac-
tor values with all three phases powered at nominal line voltages. The power
supply draws most of the total power consumed, while the measurement
circuitry draws 1-10% of the total (6-96 milliwatts per phase, depending on
the model). Due to the design of the power supply, WattNode meters draw
slightly more power at 50 Hz.
