Crestron CLT-1DIM8 User Manual

CLT- & CLX-1DIM8

Functional Summary

The Crestron 1-Feed, 8-Dimmer Terminal Block and
Module (CLT-1DIM8 and CLX-1DIM8, respectively),
are considered a single entity and must be used together.
They ship separately to permit termination of the field
wiring to the CLT-1DIM8 prior to installation of the
CLX-1DIM8, 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 (HOT and NEUTRAL) and
distribute the controlled circuits (LOAD) to the fixtures.
The module connects to the terminal block and performs
dimming control of eight 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.

Industry Compliance

This product is Listed to applicable UL Standards and
requirements by Underwriters Laboratories Inc.

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
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: Unless otherwise indicated, the lighting
system specified in this guide is modular, requiring
assembly in the field by the contractor and/or
electrician.

If you require a UL Listed panel, Crestron offers this
service through its UL Listed panel shop. This
includes complete in factory system configuration

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.

are energized.

CAUTION: Bypass jumpers are provided to allow
testing of circuits and to protect the module during
installation. When properly secured by nine screws,
the jumper on the black and red section of the
terminal block shorts the hot to dim (1 – 8) so that all
circuits are energized. Furthermore, the jumper on the
white section of the terminal block ties all 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.

NOTE: Use copper conductors only – rated 75°C

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
to 35 in-lbs. (14 – 10 AWG), 40 in-lbs.
(8 AWG), or 45 in-lbs. (6 – 4 AWG).

4. Test the circuit for electrical faults by turning on
the circuit breaker and checking that the breaker
