1 Precautions
1.1
Only qualified personnel or
licensed electricians
should install the WattNode meter. The mains voltages of 120 to 600 Vac can be lethal!
1.2
Follow all applicable local and national electrical and safety codes.
1.3
The terminal block screws are
not
insulated. Do not contact metal tools to the screw terminals 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 resistors, 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 conductors to the meter with fuses or circuit breakers (not needed for the neutral or ground wires). See
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.

Table 1
above lists the WattNode models and common circuit types. In the “Electrical Service
Types” column, when two voltages are listed with a slash between them, they indicate the line-toneutral / line-to-line voltages. The “Line-to-Neutral” and “Line-to-Line” columns show the operating ranges for the WattNode meters.
Connect the line voltages to the meter inputs as shown in the following figures for each service type. See
Figure 1

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 traditionally 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
Ø
A
,

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. 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.
□
Turn off power
before making line voltage connections.
□
Mount the WattNode meter (see
□
Connect circuit breakers or fuses and disconnects (see
).
□
Connect the line voltage wires to the meter’s green terminal block (see
□
Mount the CTs around the line conductors. Make sure the CTs face the
source
(see
□
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
).
□
Check that the CT phases match the line voltage phases (see
□
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
□
Check that all the wires are securely installed in the terminal blocks by tugging on each wire.
□
Turn on power to the meter.
□
Verify that the LED indicates correct operation (see
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 5.375 in. (137 mm) 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 sheet metal screws are included. Don’t over-tighten the screws, 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 overcurrent protection (fuse or circuit breaker).
The meter only draws 10-30 milliamps, so the rating of any switches, disconnects, 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 within sight and 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
Ø A
,
Ø B
, and
Ø C
. In the rare cases where neutral has overcurrent protection, then the overcurrent protection 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.
7
3.3.2 Line Wiring
●
Always turn off 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
ØN
values 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 models (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.
3.3.3 Grounding
The WattNode uses a plastic enclosure, insulation, and internal isolation barriers 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 disconnected on wye models (
3Y
).
3.4 Connect Current Transformers
To meet the UL listing requirements, the WattNode meter may only be used with these UL listed or recognized current transformer models. These all generate 333.33 millivolts AC at rated current.
See the current transformer datasheets for CT ratings.

See the web article
Selecting Current Transformers
for information on selecting 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
Ø A CT
is measuring the current on the same phase being monitored by the
Ø A
voltage input, 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.
Install the CTs around the conductor to be measured and connect the CT leads to the meter.
Always turn off power before disconnecting any live conductors.
Put the line conductors through the CTs as shown in
Figure 1
above.
8
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.
When installing WattNode Revenue models, be sure to only use IEEE C57.13 class 0.6 current transformers, such as the Accu-CT; other CTs are less accurate and may not provide revenue accuracy. Contact sales for more information on appropriate CTs.
3.4.1 CT Wiring
The current transformers connect to the six position black screw terminal block. Connect the white and black CT wires to the meter terminals marked
Ø A CT
,
Ø B CT
, and
Ø C CT
(see
Figure 1
above). Excess length may be trimmed from the wires if desired. 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 electrically isolated from dangerous voltages.
●
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 together, 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. See
LonWorks FTT10
Cables
(
http://www.ccontrolsys.com/w/LonWorks_FTT10_Cables
) for details.
3.6 LonWorks FT-10 Network Wiring
CCS recommends that an experienced LonWorks network installer be consulted 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 voltages, 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 polarized, so either network wire can be connected to either screw terminal.
●
FT-10 wiring is 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 recommended cabling.

Once the meter is connected to the network and power is applied, configure it on the Lon-
Works network using any of the following:
9
●
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 appropriate
Operating and Reference
Guide
for your model.
The meter does not include a display, so it is not possible to configure or monitor the meter directly, other than pressing the service pin (button) to identify the meter on the LonTalk network.
At a minimum, the
CtAmps
must be programmed with the rated amps of the attached current transformers for correct measurements.
4.2 LonWorks Service LED
The
L on
W orks 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 configuration, 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
1.0 sec
Off
1.0 sec
Red
1.0 sec
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 management 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 operate the meter directly.
The following is a brief overview of the possible remote monitoring.
10
The
L on
W orks 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 accessible 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 LonTalk 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 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 maintain 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.

Table 2: WattNode Model Service Types
* Note: the delta models have an optional neutral connection that may be used 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 current 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, 6kV for WattNode Revenue models.
Power Consumption:
The following table shows maximum volt-amperes, the power supply ranges, typical power consumption, and typical power factors with all three phases powered at nominal line voltages. The power supply consumes most of the total power, 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.
