Terminal Block and Module
Installation Guide
Description
The Crestron
®
230 V, 2-Feed, 8-Dimmer Terminal Block and Module (CLTI-2DIMU8 and
CLXI-2DIMU8) are considered single entities and must be used together. They ship
separately to permit termination of the eld wiring to the terminal block (CLTI) prior to
feed (LINE and NEUTRAL) and distribute the controlled circuit (LOAD) to the xtures. The
module connects to the terminal block and performs dimming control of LED,
incandescent, magnetic low-voltage, or dimmable 2-wire uorescent lighting loads.
The maximum load is 2.5 A per channel; the maximum load is 20 A total for the
CLXI-2DIMU8. The CLXI-2DIMU8 accepts two 10 A feeds that can be different phases.
An oversize heat sink dissipates heat efciently. There are LEDs on the module to indicate
communication to a Cresnet
®
network, input power to the module, and output power to
the load.
The CLTI terminals and CLXI modules are shown in the following illustrations.

NOTE: Unless otherwise indicated, the lighting system specied in this guide is
modular, requiring assembly in the eld by a licensed electrician in accordance with all
national and local codes.
If an assembled UL

Terminal Block Installation and Field Wiring
Terminal block installation requires installation of the supplied adhesive label and the
terminal block. The adhesive label provides the labeling for each terminal in the terminal
block and is designed to accommodate installation into the left or right side of a cabinet.
Refer to the illustrations that follow for details.
WARNING: The CLXI-2DIMU8 may be powered from multiple circuit breakers.
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
used only in double-wide enclosures.
1. Remove the backing from the left- or right-side 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.
3. Use the two supplied self-tapping Phillips pan head screws (8B x 1/4 in length) to
secure the terminal block to the Crestron Automation Enclosure.
CAUTION: Bypass jumpers are provided to allow testing of circuits and to protect
the module during installation. When properly secured by ve screws, each of the
two jumpers on the brown and red sections of the terminal block shorts the line in
to dim out so that the circuit is energized. 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
and Wiring” for details.
Furthermore, the two jumpers on the blue sections of the terminal block tie the
neutral ins to the neutral outs. These jumpers should never be removed.
NOTE: Use copper conductors only—rated 75 °C or greater.
4. Turn off the circuit breakers.
5. Connect the circuit feed (line and neutral) and controlled circuit (load) wires to the
terminal block per the markings provided on the wiring label. Terminal blocks accept
one 2.5–6 mm
2
wire. Strip the wires to 12 mm (1/2 in). Tighten terminal blocks to
1 Nm.
6. Grounding terminal blocks are available in the cabinet for termination of ground
wires. Tighten to 4 Nm (2.5–6 mm
2
), 4.5 Nm (10 mm
2
), or 5.1 Nm (16–25 mm
2
).
7. Test each circuit for electrical faults by turning on each of the circuit breakers and
checking that the breakers do not trip and that power is delivered to the proper
loads.

Specications
Specications are listed in the table below.
Installation
A licensed electrician must mount the terminal block and module into a Crestron
Automation Enclosure 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 10° to 40 °C (32° to 104 °F). The
relative humidity must be 0% to 90% (noncondensing).1
NOTE
: For 2-feed systems, the two input lines can be different phases.
NOTE: When connecting to an arc fault breaker, ensure the load does not exceed
1,000 W total. Crestron certied breakers have a 2,000 W limit.
IMPORTANT NOTES: When controlling magnetic low-voltage transformers:
• Do not use a CLXI-2DIMU8 module for switching or dimming large magnetic
transformers (>100 VA).
• Do not connect more than eight magnetic transformers on any one output, regardless
of lamp wattage.
• Do not hot plug transformers or add or remove bypass jumpers while the output
channel is energized.
• Do not mix magnetic and electronic transformers on the same output channel.
Failure to follow the guidelines above can lead to damage of the dimmer module and
transformers.
NOTE: Before using the CLXI-2DIMU8, ensure the device is using the latest rmware.
Check for the latest rmware for the CLXI-2DIMU8 at www.crestron.com/rmware. Load
the rmware onto the device using Crestron Toolbox™ software.
Install terminal blocks along the left side of single-wide enclosures and along the outside
edges (left and right sides) of double-wide enclosures. Install modules 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 the
units on the right side so that they can be properly wired. Refer to the illustrations that
follow 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.

Troubleshooting
The following table provides corrective actions for possible trouble situations. If further
assistance is required, please contact a Crestron customer service representative.
The module displays error codes using the dimmer output LEDs. The LED blinks a pattern,
such as 1-2 or 2-4, to indicate the error on that output. For example, a 1-2 error blinks the
LED 1 time, pauses for 1 second, blinks two times, pauses for two seconds, and then
repeats until the error is corrected. A 2-4 error blinks the LED blinks two times, pauses for
1 second, blinks four times, pauses for two seconds, and then repeats until the error is
corrected. Refer to the following table for possible corrections.
5. Turn on the circuit breakers and verify that the green PWR LED on the module lights,
the breakers do not trip, and the power is delivered to the loads.
6. Turn off the circuit breakers.
NOTE: Before removing the bypass jumpers, make sure to properly connect and
program the control system that provides functionality to the system.
7. Remove the bypass jumpers on the brown and red sections of the terminal block.
The jumpers on the blue sections of the terminal block must remain installed.
Module Installation and Wiring
CAUTION: The module contains electrostatic sensitive devices (ESDs); the unit must be
handled from the metal chassis. Do not touch the PC board or components.
NOTE: Install the modules after the enclosure has been completely wired. Refer to
“Terminal Block Installation and Field Wiring” for details.
Install and wire the module.
1. Turn off the circuit breakers.
2. Use the four supplied self-tapping Phillips pan head screws (8B x 1/4 in length) to
secure the module to the enclosure.
3. 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 prestripped to 12 mm (1/2 in). Tighten to 1 Nm.
4. If the module is being installed above another module within the enclosure, attach
the supplied module interconnect cable between the two modules. The illustration
that follows shows 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.

8. Turn on the circuit breakers.
NOTE: Power must be supplied to LINE 1 for the module to communicate with the
control system or for any of the circuits to operate.
9. If the program is not yet running, test the loads using Local mode.
