Questions on wiring?
Lutron may be able to help with charts of Wallstations
versus distance.
?
Total length of Control Link may be no more than 2,000 feet. This
distance is based on proper shielding on the twisted shielded pair,
and on #12 AWG wire on the wires to terminal 1 and terminal 2 of
the Control Link. If unapproved cable or smaller wire is used, this
limit is affected:
Total number of Wallstations, Control Units, Control Interfaces or
Circuit Selectors = 33 maximum.
Total number of Control Unit addresses = 8 maximum
Note: GRX-4116/4516 has 2 addresses
GRX-4124/4524 has 3 addresses
Total number of Wallstation or Control Interface addresses = 16
maximum.
Notes:
■Make wire connections inside the wallbox and GP panel or in a
junction box (by others) within 8 ft. (2.4 m) of the terminal.
■All control wiring is Class 2/PELV. Do not place any of these
wires in with line voltage (mains voltage) wiring.
■The order of controls within the control wiring is not important.

Feed and Load Wiring
Temporary Lighting
You do not need to install a temporary distribution panel. Place load
wires into the appropriate terminal blocks.
Each Input Breaker can supply power to a load while the bypass
jumper protects the dimmer from load faults.
Caution!GP panels require entry of wires as specified.
Improper entry will block serviceable parts, and impede
air flow through the panel.
Caution! Common Neutrals are not permitted.
Run separate Neutrals for each load circuit.

Notes:
■GP3 Main Breakers can be removed to ease installation of feed
wiring.
■For 230V and 240V panels, ‘Hot’ is referred to as ‘Live’.
Therefore, terminals will be labeled DL, SL, and L.
■Run wiring so that line (mains) voltage wiring will be at least
6 ft. (1.8 m) from sound or electronic equipment and its wiring.
■Hot (H) is used for bypass on all panels. It can also be used as a
protected Hot output on GP3, 8, 12, 16, 20, and 24 (added Hot
current plus Load current must not exceed breaker limits).
Feed and Load Wiring
Load Wiring:
For all load types except Hi-lume®FDB or Eco-10™fluorescent
dimming ballasts.
Dimmed Hot (DH) must be used for Non-Dim loads.

Caution! Verify with electronic low voltage transformer
or ballast manufacturer that product can be controlled
with a phase control dimmer before bypass jumpers are
removed.
Caution! Switched Hot (SH) must only be used for Hi-
lume FDB or Eco-10 loads. Use the Dimmed Hot (DH)
for all Non-Dim Load Types.
Danger! Feed-through panels, such as GP4, may be
fed by multiple circuits. Locate and lock each supply
breaker in the off position before wiring feed or loads.
Warning! CE marked panels are appliances. A
distribution panel must provide a main circuit breaker
that does not exceed the rating of the panel.

Install Wallstations
and Activate Loads
STEP 7: Install Wallstations
After wiring, setting address switches, and setting function switches,
mount the Wallstations. Refer to detailed mounting instructions
packaged with each control.
STEP 8: Activate Loads in Bypass
A. Complete load wiring.
B. Check that the bypass jumpers are in place.
These jumpers protect the dimmers from faults and must be
used to check load wiring when it is installed or modified.
Warning! For GP3 or GP4, the input breaker of Circuit
1 powers the control wiring as well as Circuit 1's
dimmer and load. Steps 8 and 9 should be performed
concurrently for these panels.
C. Turn circuit breaker 1 ON.
The load should energize, the breaker should not trip, and total
load current must be within the Circuit Breaker's limit and less
than 16A.
D. Repeat ‘C.’ for each circuit with completed load
wiring.
Warning! DO NOT remove bypass jumpers at this time.
Caution! For proper dimming performance fluorescent
lamps must be operated at full intensity for 100 hours
prior to dimming.
See Maintenance Reference sheet in the Reference
Section of this guide.
Note: For those who purchased Start Up with their Lutron Dimming
System — you may want to stop here and have the Lutron Field
Engineer set-up the system. Please call for a Start Up visit at least
10 working days before your requested date.

once per second)
* The Circuit Selector may take up to 1 minute to properly identify a
device on the link. During this time, a rapid flashing pattern may be
observed.
LED Status
1. Flashes once per second.
2. Blank.
3. Flashes rapidly*.
As soon as a GRX-4000 Series Control Unit is addressed, check
that the Data OK LED begins to flash on the Circuit Selector.
Flashing indicates that the panel recognizes the communication
from a GRX-4000 Series Control Unit.
Note: As soon as a GRX-4000 Series Control Unit is addressed,
Wallstations will no longer have any affect on the GRX-4000 Series
Control Units. The Wallstation communication will be reestablished

Notes:
■The Circuit Selector Load Type must be set for Non-Dim on
each circuit assigned to this zone.
■With 4 LEDs, the load will operate on a Last On, First Off
basis. Load turns ON at the end of a fade to full and OFF at the
beginning of a fade from full.
■With 5 LEDs, the load will operate on a First On, First Off
basis. Load turns ON at the beginning of a fade to full and
OFF at the beginning of a fade from full.
Repeat Step B for all zones controlling a Non-Dim Load Type.
C. Press and hold top and bottom scene buttons until scene LEDs
stop sequencing.
D. Repeat Steps A - C for all other GRX-4000 Series Control Units
with Non-Dim zones.
