Crestron CLT-2IND, CLX-2IND, CLT-4IND User Manual

Functional Summary

The CLT/CLX-2IND is a 2-inductor terminal block and
module kit while the CLT/CLX-4IND is a 4-inductor
terminal block and module kit. Inductor modules are
typically used to reduce hum from incandescent lamps
that are connected to dimmer modules in a Crestron
lighting system. These kits can be mounted in any
Crestron Automation Enclosure (CAEN-Series
Enclosures). The terminal block is for connecting wires
into and out of the inductor module. The inductor is wired
in series between the output of the dimmer module and
the load. The maximum load for any inductor in the
module is 16 amps.

Each of these Terminal Block and Module kits is
considered single entities and must be used together. The
terminal blocks (CLT-2IND and/or CLT-4IND) are
shipped separately from their respective modules
(CLX-2IND and CLX-4IND) to permit termination of the
field wiring to the terminal block prior to installation of
the module, as described in this guide.

Installation

The 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.
Mount in a well-ventilated area. The ambient
temperature must be 32°F to 104°F (0°C to 40°C).
The relative humidity must be 10% to 90% (non­condensing).

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
that they can be properly wired. Refer to the illustrations
shown in the next column when considering the location
of terminal blocks and modules within an enclosure.

NOTE: Inductor modules and terminal blocks
should be installed above the dimmer modules,
towards the top of the CAEN enclosure.

Terminal Block & Module Crestron CLT- & CLX-2IND/4IND

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 on this and the following 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.

NOTE: Use copper conductors only – rated 75°C

2. With the circuit breaker turned off, connect the
dimmer module output (IN) and the load (OUT)
wires to the IND terminal block per the markings
provided on the wiring label (as shown in the
following diagrams). Terminal blocks accept one
14 - 10 AWG wire. Wires should be stripped to
½ inch. Tighten terminal blocks to 9 in-lbs.

3. Test the circuit for electrical faults by turning on
the circuit breaker and checking that the breaker
does not trip and that the proper lighting loads
are energized.
