Crestron CLT- & CLX-1DIM4 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 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 five-

position bypass jumper on the black and red

section of the terminal block. The bypass jumper

on the white section of the terminal block

remains installed. Refer to the figures in the next

column for a close-up of the jumpers.

NOTE: Before the five-position bypass jumper,

shown in the illustration, is 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.
