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 (ra-
tio) 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
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.

2 Overview
Congratulations on your purchase of the WattNode
®
BACnet
®
or WattNode
®
Revenue for BACnet
®
watt/watt-hour transducer (meter). It is designed for use in demand side management (DSM),
submetering, energy monitoring, billing and renewable energy applications. The WattNode meter
communicates on an EIA RS-485 two-wire bus using the BACnet protocol.
The WattNode Revenue (RWNC) version meets the ANSI C12.1 standard for revenue metering
when used with IEEE C57.13 class 0.6 current transformers, such as the Accu-CT
®
.
WattNode BACnet models are BTL (BACnet Testing Laboratories) certified for interoperability.
