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
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.

Note 1: Not all terminal blocks receive a connection.
Note 2: The power feed to the Control Unit and L

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
separation and is flexible to allow access to the terminals. The barrier must be in place when installation is
complete.
