Crestron CLT-2DIM8 User manual

CLT- & CLX-2DIM8
Functional Summary
The Crestron®2-Feed, 8-Dimmer Terminal Block and
Module (CLT-2DIM8 and CLX-2DIM8, respectively),
are considered a single entity and must be used together.
They ship separately to permit termination of the field
wiring to the CLT-2DIM8 prior to installation of the
CLX-2DIM8, as described in this guide. They can be
mounted in any Crestron Automation Enclosure (CAEN-
Series 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 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 for
circuits 1 through 4 and 16 amps total for circuits 5
through 8. The unit requires 120VAC 50/60 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: The two input lines must be the same phase or
split phase.
NOTE: When connecting to an Arc Fault Breaker, the
load should not exceed 1000 watts per breaker.
Industry Compliance
This product is Listed to applicable UL Standards and
requirements by Underwriters Laboratories Inc.
(E103692)
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
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% (non-condensing).
Terminal blocks are installed along the left side of single-
wide 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 double-
wide 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: Modules and terminal blocks must be
installed into the lowest available spaces and
continue toward the top of the enclosure.

4. Test the circuit for electrical faults by turning on
the circuit breaker and checking that the breaker
does not trip and that power is delivered to the
loads.
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.

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 installed on the
terminal blocks to allow testing of circuits and to
protect the module during installation. When properly
secured by five screws, the bypass jumpers on the
black and red sections of the terminal block short the
hot to dim so that all circuits receive power. Do not
remove these 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. Jumpers are also installed on the white sections
of the terminal block and tie all neutrals together.
These jumpers should never be removed.

2. With the circuit breaker turned off, connect the
circuit feeds (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.
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).

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.
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.

4. Turn on the circuit breaker and verify that the
green PWR LED on the module lights, the
breaker does not trip, and power is delivered to
the loads.
5. Turn off the circuit breaker and remove the
bypass jumpers on the black and red sections of
the terminal block. The jumpers on the white
sections of the terminal block must remain
installed. Refer to the figures in the next column
for a close-up of the jumpers.
NOTE: Before the bypass jumpers, shown in the
illustration, are removed, the Crestron Professional
Automation Computer (PAC2), which provides
control to the system, should be properly connected
and contain a valid program to provide control of the
module.
