CLT- & CLX-2DIM2
Functional Summary
The Crestron 2-Feed, 2-Dimmer Terminal Block and
Module (CLT-2DIM2 and CLX-2DIM2, respectively),
are considered a single entity and must be used together.
They ship separately to permit termination of the field
wiring to the CLT-2DIM2 prior to installation of the
CLX-2DIM2, as described in this guide. They can be
mounted in any Crestron Automation Enclosure (CAENSeries Enclosures). The terminal block is designed to
terminate two circuit feeds (HOT and NEUTRAL) and
distribute the controlled circuits (LOAD) to the fixtures.
The module connects to the terminal block and performs
dimming control of two incandescent, magnetic low
voltage, neon, cold cathode, or dimmable 2-wire
fluorescent lighting loads. The maximum load is 16 amps
for each controlled circuit (32 amps total per module).
The unit requires 120VAC 60 Hz, 1 phase input voltage.
An oversize heat sink dissipates heat efficiently. There are
LEDs on the module to indicate communication to a

or split phase.
NOTE: When connecting to an Arc Fault Breaker,
the load should not exceed 1000 watts.
that they can be properly wired. Refer to the illustrations
shown below when considering the location of terminal
blocks and modules within an enclosure.
NOTE: Modules and terminal blocks must be
installed into the lowest available spaces and
continue toward the top of the enclosure.

Installation
Terminal block and module must be mounted into a
Crestron Automation Enclosure by a licensed electrician,
in accordance with all national and local codes.
CAUTION: This equipment is for indoor use only
and needs to be air-cooled. Mount in a wellventilated area. The ambient temperature must be
32°F to 104°F (0°C to 40°C). The relative humidity
must be 0% to 90% (non-condensing).
Terminal blocks are installed along the left side of singlewide enclosures and along the outside edges (left and
right sides) of double-wide enclosures. Modules are
installed along the right side of single-wide enclosures
and side-by-side in the center of double-wide enclosures.
When installing modules and terminal blocks in a doublewide enclosure, be sure to invert units on the right side so

Terminal Block Installation and Field Wiring
1. Use the two supplied self-tapping pan Phillips
screws (8B x ¼ length) to secure the terminal
block and the appropriate (left or right) wiring
label to the Crestron Automation Enclosure. The
wiring label lies beneath the terminal block as
shown in the two wiring diagrams on this page.
NOTE: Both left and right wiring labels are
provided. The left-side labels are common for both
single and double-wide enclosures. The right-side
labels are only used in double-wide enclosures since
the modules and terminal blocks along the right side
must be inverted when mounting.
CAUTION: Bypass jumpers are provided to allow
testing of circuits and to protect the module during
installation. When properly secured by two screws,
the jumpers on the black and red sections of the
terminal block short the hot to dim so that all circuits
are energized. Furthermore, the jumpers on the white
sections of the terminal block tie the neutrals
together. Do not remove any bypass jumpers until all
feed and load wiring has been completed, the circuit
has been tested for electrical faults, and the module
has been installed. Refer to “Module Installation” on
next page.

2. With the circuit breaker turned off, connect the
circuit feed (HOT and NEUTRAL) and
controlled circuit (LOAD) wires to the terminal
block per the markings provided on the wiring
label (as shown in the diagrams on this page).
Terminal blocks accept one 14 - 10 AWG wire.
Wires should be stripped to ½ inch. Tighten
terminal blocks to 9 in-lbs. Do not over tighten.
3. Grounding terminal blocks are available in the
cabinet for termination of ground wires. Tighten

Module Installation
CAUTION: Module contains electrostatic sensitive
devices (ESDs); unit must be handled from metal
chassis – do not touch PC board or components.
NOTE: Modules are to be installed after enclosure
has been completely wired. Refer to the terminal
block installation procedure on page 2 for details.
1. Use the four supplied self-tapping pan Phillips
screws (8B x ¼ length) to secure the module to
the enclosure.
2. As shown in the wiring diagrams (next column),
connect the wires from the module to the
terminal block. Each wire exits the module
directly in line with, and is the same color as, the
terminal to which it should be connected. Wires
are pre-stripped to ½ inch. Tighten to 9 in-lbs.
Do not over tighten.
3. If the module is being installed above another
module within the enclosure, attach the supplied
module interconnect cable between the two
modules. The illustration below depicts the area
within a double-wide enclosure where the
corners of four modules meet.
NOTE: One wire on the module interconnect cable
may be a different color from the rest. The color has
no bearing on its orientation during installation.
