Consumption CT installation
in grid-tied systems (load only configuration)
Consumption CTs are installed on the home loads panel when a site
needs to only monitor the consumption by the home loads.
Make sure that the main load center wires are de-energized until you
have secured the CT wires in the terminal blocks .
Clamp the red and black C1 CT on the load center feed wire Line 1
(matching the IQ Gateway's "L1" voltage terminal) with the CT arrow
pointing toward the load (away from the grid).

Risk of electrocution and equipment damage! Do not install CTs when
