220-240V/CE Control Interface
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.
Caution: Multiple feeds may enter this enclosure. Locate and lock each feed circuit breaker/MCB in the OFF position
before wiring the Interface.
Proper short circuit and overload protection must be provided at the distribution panel. You can use up to a 20A (16A 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 #12-22 AWG (0.5-2.5 mm
2
) wires per terminal.
Strip 3/8 in. (10 mm) of insulation from wires.
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, one feed can be jumpered inside the enclosure (as shown).
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 Hot/Live terminals (L
1/H1 & L2/H2).
L
1/H1 is the Hot/Live feed to power the lighting load.
L
2/H2 is the Hot/Live feed that powers internal circuitry of the GRX-
TVI.
L2/H2 has a 100-127V connection and a 220-240V connection - use
only the one corresponding to line voltage for your application.
Note 1: Not all terminal blocks receive a connection.
Note 2: The power feed to the Control Unit and L2/H2 of the GRX-
TVI must be the same phase!
Class 2/PELV, 0-10V wiring from a ballast to the GRX-TVI-
CE must be separated from the power wiring. Enter the
Class 2/PELV wires through the knockout adjacent to the 0-10V terminal blocks. The Nomex
®
barrier ensures
separation and is flexible to allow access to the terminals. The barrier must be in place when installation is
complete.
GRX-TVI Internal Terminal Block Label Definitions
Use only one input according to Input Voltage:
L
2/H2 240V Power input for GRX-TVI control (line/mains voltage must be 220-240V)
L
2/H2 127V Power input for GRX-TVI control (line/mains voltage must be 100-127V)
N2 Neutral for GRX-TVI control
DL
2/DH GRAFIK Eye 3000 Series Control Unit Lighting Zone connection (Phase Control Input to GRX-TVI)
L
1/H1 Power input for lighting load
N
1 Neutral for lighting load (2 terminals provided and internally tied together — one for input neutral and one
for load neutral)
SL
1/SH1 Switched output to power lighting load
+ - 0-10V control signal wires (
ballast must provide a 0-10V source only)
