Mounting
Find a suitable location for mounting.
• Decide on the proper location for the GRX-TVI (NEMA Type 1
enclosure, indoor use only).
• The environment where the GRX-TVI is placed must have an
ambient temperature range of 32 to 104 °F (0 to 40 °C).
• Mount the enclosure vertically on a wall (screws not provided).
• Mounting method must be able to support weight and forces
applied during installation.
• Internal relays will click while in operation — mount where
audible noise is acceptable.

Wiring
1. Turn power off at fuse box or circuit breaker
Warning - Shock Hazard. To avoid the risk of electric shock,
locate and remove fuse or lock circuit breaker in the OFF
position before proceeding. Wiring with the power ON could
result in personal injury or death.
Note: Multiple power feeds could be provided. Ensure that all feeds
are off before wiring.
2. Wire control per appropriate wiring diagram (see next page)
using wire connectors provided. Dots on diagrams represent wire
connectors.
• Wiring Diagram A shows 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 on Page 3).
• Wiring Diagram B shows a GRX-TVI wired from two separate
distribution panels that may be different phases or voltages.
• Use the internal terminal block label to see where to land wires.
- The label shows two separate
Line/Hot terminals (L1/H1 &
L2/H2). L1/H1 is the Line/Hot feed
to power the lighting load.
L2/H2 is the Line/Hot feed that
powers internal circuitry of the
GRX-TVI.
Note 1: Not all terminal blocks are
required to have a connection for
proper operation.
Note 2: The power feed to the Control Unit (DL2/DH2) and L2/H2 of
the GRX-TVI must be the same phase!
Class 2/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 fl exible to allow access
to the terminals. The barrier must be in place when installation is
complete.
