WIRING DIAGRAMS

WARNING

RISK OF ELECTRIC SHOCK

CT negative terminals are referenced to the meter’s neutral and may be at elevated voltages

·Do not contact meter terminals while the unit is connected

·Do not connect or short other circuits to the CT terminals

Failure to follow these instructions can result in death or serious injury.
