CLT- & CLX-1DIM4
The Crestron 1-Feed, 4-Dimmer Terminal Block and Module (CLT-1DIM4 and CLX-1DIM4, respectively), are considered a single entity and must be used together. They ship separately to permit termination of the field wiring to the CLT-1DIM4 prior to installation of the CLX-1DIM4, as described in this guide. They can be mounted in any Crestron Automation Enclosure (CAENSeries Enclosures). The terminal block is designed to terminate the circuit feed (LINE and NEUTRAL) and distribute the controlled circuit (LOAD) to the fixtures. The module connects to the terminal block and performs dimming control of four incandescent, magnetic low voltage, neon, cold cathode, or dimmable 2-wire fluorescent lighting loads. The maximum load is 16 amps for any controlled circuit, limited to 16 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 Cresnet network, input power to the module, and output power to the load.
NOTE: When connecting to an Arc Fault Breaker, the load should not exceed 1000 watts total.
This product is Listed to applicable UL Standards and requirements by Underwriters Laboratories Inc.
(E103692)
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 well-ventilated area. The ambient temperature must be 32°F to 104°F (0°C to 40°C). The relative humidity must be 0% 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 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.

Terminal Block & Module |
Crestron CLT- & CLX-1DIM4 |
NOTE: Unless otherwise indicated, the lighting system specified in this guide is modular, requiring assembly in the field by a licensed electrician, in accordance with all national and local codes.
If you require a UL Listed panel, Crestron offers this service through its UL Listed panel shop. This includes complete in factory system configuration and assembly by Crestron for an additional fee.
Terminal Block Installation and Field
Wiring
NOTE: Both left-side and right-side adhesive wiring labels are provided. The left-side labels are used in both single and double-wide enclosures. The right-side labels are only used in double-wide enclosures.
1.Remove the backing from the left or right adhesive wiring label.
2.Apply the adhesive label by aligning the holes in the label with the holes on the Crestron Automation Enclosure where the terminal block is to be mounted. The wiring label lies beneath the terminal block as shown in the two wiring diagrams on this page.
3.Use the two supplied self-tapping pan Phillips screws (8B x ¼ length) to secure the terminal block to the Crestron Automation Enclosure.
CAUTION: A bypass jumper is provided to allow testing and to protect the module during installation. When properly secured by five screws, the jumper on the black and red section of the terminal block shorts the LINE in to DIM out so that the circuit is energized. Do not remove the bypass jumper 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.
Furthermore, the jumper on the white section of the terminal block ties the neutral in to the neutral outs. This jumper should never be removed.
NOTE: Use copper conductors only – rated 75°C
4.With the circuit breakers turned off, connect the circuit feed (LINE 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.
5.Grounding terminal blocks are available in the cabinet for termination of ground wires. Tighten to 35 in-lbs. (14 – 10 AWG), 40 in-lbs.
(8 AWG), or 45 in-lbs. (6 – 4 AWG).
6.Test the circuit for electrical faults by turning on the circuit breaker, checking that the breaker does not trip, and that power is delivered to the proper loads.
