Wiring Diagram - Monitoring Three-phase Energy using the ZW Wireless Data Node and the Wattnode kWh Transducer

Attached is a wiring diagram that shows how to connect a Wattnode kWh Transducer to a HOBO ZW-008 or ZW-005 wireless data node to log energy consumption on a 3-phase circuit.

Note: The wiring from the ZW to the Wattnode would be the same for 2-phase (or split-phase) and single-phase circuits.

Warning:

Installing transducers in an energized electrical enclosure or on any energized conductor can result in severe injury or death. These transducers are for installation by qualified personnel only. To avoid electrical shock, do not perform any installation or servicing of these transducers unless you are qualified to do so. Disconnect and lock-out all power sources during installation and servicing. Please read transducer user manuals for instructions and use.
