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.
1.9 Symbols
Read, understand, and follow all instructions including warnings
and precautions before installing and using the product.
Potential Shock Hazard from Dangerous High Voltage.
Functional ground; should be connected to earth ground if possible,
but is not required for safety grounding.

2 Overview
Congratulations on your purchase of the WattNode
transducer (meter). The WattNode meter enables you to make power and en-
ergy measurements within electric service panels avoiding the costly installa-
tion of subpanels and associated wiring. It is designed for use in demand side
management (DSM), submetering, and energy monitoring applications. The
WattNode meter communicates on an EIA RS-485 two-wire bus using the
Modbus RTU protocol.
2.1 Additional Literature
See the Continental Control Systems, LLC website (www.ccontrolsys.com)
for product pages, datasheets, and support pages for all WattNode meter mod-
els and current transformers. Each WattNode model has an
Reference Guide
and interface.
2.2 Electrical Service Types
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-to-neutral / line-to-line voltages. The
"Line-to-Neutral" and "Line-to-Line" columns show the operating ranges for
the WattNode meters.
