GRX-TVI Control Interface
Phase Control to 0-10 V
-
100-277 V
~
50 / 60 Hz
Description
The GRX-TVI provides 0-10 V
-
control and ballast/driver switching
capabilities in one enclosure. The GRX-TVI gives a 100-277 V
~
dimmer the ability to control current sourcing 0-10 V
-
ballasts
or LED drivers (loads) powered by 100-277 V
~
. The dimmer can
be forward phase,reverse phase, or center phase
(for a sample of
approved dimmers, see the list on spec sheet P/N 369247). The
GRX-TVI provides switching relays that can handle the in-rush
current for a circuit of ballasts/drivers. The GRX-TVI can also be
used to switch any of the load types listed below.

Important Installation Information
• Install in accordance with all national and local electrical codes.
• Check for short-circuited loads during new installations before wiring
the GRX-TVI.
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.
• Proper short circuit and overload protection must be provided at the
distribution panel. You can use up to a 20 A (16 A for CE) maximum
circuit breaker/MCB or equivalent (tripping curve C according to
IEC 898/EN60898 is recommended) with adequate short circuit
breaking capacity for your installation.
• Terminal blocks are rated for two 12 to 20 AWG (2.5 to 0.5 mm
2
)
wires per terminal.
• Strip 3/8 in (10 mm) of insulation from wires.
Note:
277 V
~
operation on the control terminal was a design feature
added September 2013. To check whether your TVI has this feature,
please ensure the front label of the TVI shows the acceptable voltage
range as 100 - 277 V
~
for the control input. Prior revisions of the unit
had (2) L2/H2 terminals (one for 120 V
~
and one for 240 V
~
). The
current design of the unit accepts a universal voltage (100 - 277
V
~
),
so either of these terminals can be used for the control feed. They are
internally tied together.
