CLTI- & CLXI-1MC4
Functional Summary
The Crestron 1-Feed, 4-Motor Terminal Block and
Module (CLTI-1MC4 and CLXI-1MC4, respectively), are
considered a single entity and must be used together.
They ship separately to permit termination of the field
wiring to the CLTI-1MC4 prior to installation of the
CLXI-1MC4, 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 motors.
The module connects to the terminal block and performs
control of four bi-directional motors. The maximum load
is 8 amps (1 HP) for any controlled circuit, limited to 13
amps total per module. The unit requires 230VAC 50 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.
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
0°C to 40°C (32°F to 104°F). The relative humidity
must be 0% to 90% (non-condensing).

(RIGHT)
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: Modules and terminal blocks must be
installed into the lowest available spaces and
continue toward the top of the enclosure.

Terminal Block Installation and Field Wiring
1. Use the two supplied self-tapping pan Phillips
screws (8B x ¼-inch (6 mm) 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: The jumper on the blue section of the
terminal block ties all neutrals together. Do not
remove the jumper.
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 2.5 - 6.0 mm2 wire.
Wires should be stripped to 12 mm. Tighten
terminal blocks to 1 Nm. Do not over tighten.

3. Grounding terminal blocks are available in the
cabinet for termination of ground wires. Tighten
to 4 Nm (2.5 - 6.0 mm
2
), 4.5 Nm (10.0 mm2), or
5.1 Nm (16 – 25 mm2).
4. Test the circuit for electrical faults by connecting
LINE to OPEN 1. Switch on the circuit breaker
and check that it does not trip and that the load
connected to OPEN 1 is receiving power.
Switch off the circuit breaker, remove the
connection between LINE and OPEN 1, and
repeat this step for CLOSE 1 and then
sequentially for each OPEN and CLOSE motor
connection.

Crestron CLTI- & CLXI-1MC4 Terminal Block & Module
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-inch (6 mm) 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 12 mm. Tighten to 1 Nm. Do
not over tighten.
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.
