L2 / H2 terminals are tied to each other
internally. It is the Line / Hot feed that
powers the internal circuitry of the
GRX-TVI. Use the appropriate voltage in
the range of 100—277 V~. Refer to the
Note on the first page of the GRX-TVI
Specification Submittal.
L1 / H1 is the Line / Hot feed that
powers the Switched Line / Hot
output to the load. Use any
voltage in the range of
100—277 V~.
Note: If the voltage of the ballast / driver is
different from the voltage of the control device,
they should come from different distribution panels
(demonstrated above).
If the control side plus the load side current is
greater than the circuit breaker rating, and the
voltages of load and control are the same level,
follow Diagram O.

The brass screw terminal is not used. Tighten the brass screw terminal. Do not connect
the brass screw terminal to ground or to any other wiring.
