Lutron GRX-TVI Power Interfaces
369247e 4 07.07.16
Wiring Diagrams
• Each terminal can accept up to two 12 AWG
(2.5 mm
2
) conductors.
• L1 / H1 is the Line / Hot feed to power the load.
• L2 / H2 (on the control circuit terminals) supplies
operating power for the Ten Volt Interface.
• Wiring Diagrams A, C, E, G, I, and M show a
GRX-TVI wired from one distribution panel. If the
power requirement of the complete system is less
than an MCB / circuit breaker rating and L1 / H1
and L2 / H2 are both coming from the same phase,
one feed can be jumpered inside the enclosure (as
shown).
• Wiring Diagrams B, D, F, H, J, L, and N show a
GRX-TVI wired from two separate distribution panels
that may be different phases or voltages.
• Wiring Diagram O shows a GRX-TVI wired from one
distribution panel with 2 separate feeds.
• Make sure L2 / H2 and DL2 / DH2 (Dimmed
Line / Dimmed Hot) are fed from the same breaker
that powers the control unit.
• Run separate neutrals for load circuit and control
circuit- no common neutrals.
• NEC
® Class 2 / IEC PELV, 0—10 V- wiring from a
ballast / driver to the GRX-TVI must be separated
from the power wiring. Enter the Class 2 / PELV
wires through the knockout adjacent to the
0—10 V- terminal blocks. The barrier ensures
separation and is flexible to allow access to the
terminals. The barrier must be in place when
installation is complete.

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.
