Crestron CLTIBN-4IND Operating Manual

CLTIBN Terminal Blocks

Functional Summary

The Crestron® CLTIBN series of terminal blocks with circuit breakers provide an additional wiring option when installing Crestron CLXI-series modules in a Crestron CAENIB automation enclosure. CLTIBN terminal blocks feature 10A type “C” load-side breakers that offer additional circuit protection where desired, or where required by local electrical codes. CLTIBN terminal blocks ship separately from their corresponding CLXI modules to permit termination of the field wiring to the CLTIBN prior to installation of the module. Every CLTIBN includes a door kit and an adhesive circuit label (for labeling circuits) to be installed on the cover of the CAENIB enclosure. This door kit allows access to the circuit breakers located on the CLTIBN without removing the cover of the CAENIB enclosure.

Industry Compliance

This product complies with the essential requirements of all applicable EU directives.

NOTE: For applications where an RCCBO (Residual Current Circuit Breaker with Overload) is needed, the CLTIBN’s breaker must be replaced with an RCCBO (supplied by other). Note that the presence of an RCCBO requires the CLXI module to be mounted in a different location to allow for the added size of the new breaker. Refer to the latest version of the CAENIB Installation Guide (Doc. 6562) which is available for download from the Crestron website (

NOTE: To insure proper fit, terminal blocks and modules must be installed at the locations indicated in the latest version of the CAENIB Installation Guide.

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

Installation

The terminal block and module must be mounted into a CAENIB 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 0°C to 40°C (32°F to 104°F). The relative humidity must be 0% to 90% (noncondensing).

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 and next page when considering the location of terminal blocks and modules within an enclosure.

Terminal Block Installation and Field Wiring

CAUTION: RISK OF ELECTRIC SHOCK—MORE THAN ONE DISCONNECT SWITCH MAY BE REQUIRED TO DE-ENERGIZE THE EQUIPMENT BEFORE SERVICING.

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 only used in double-wide enclosures.

Using the diagram in the next column as reference, install the terminal block in the CAENIB enclosure.

1. Using a Phillips screwdriver, remove the four screws securing the cover plate to the CLTIBN and remove the cover plate.

2. Remove the backing from the left or right adhesive wiring label. Place the label in the location where the CLTNIB is to be mounted on the CAENIB. Align the holes in the label with the appropriate holes in the CAENIB. Refer to the latest version of the CAENIB Installation Guide for information on mounting locations.

3. Use the four 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 terminal block-tomodule wiring diagrams on page

NOTE: When installed with other terminal blocks, CLTI-4IND and CLTI-2IND terminal blocks should be installed at the top of a CAENIB enclosure and grouped with other CLTI-4IND and CLTI-2IND terminal blocks.

NOTE: Use copper conductors only – rated 75°C.

4.

Module Installation

CAUTION: CLXI modules contain electrostatic sensitive devices (ESDs); units must be handled from metal chassis – do not touch PC boards or components.

NOTE: CLXI modules are to be installed after the enclosure has been completely wired and load wiring has been verified. Refer to the terminal block installation procedure on the previous page for details.

1. Use the four supplied self-tapping screws (8B x ¼ (6 mm) length) to secure the module to the enclosure.

2. Connect the CLXI modules to their corresponding CLTIBN terminal blocks as shown in the terminal block-to-module wiring diagrams that start on page provided for installation on the right and left sides of a CAENIB enclosure. Wires are prestripped to 12 mm. Tighten terminal blocks to 1 Nm. Tighten circuit breaker lugs to 1.2 Nm.

NOTE: Do not remove any factory-installed jumper wires or bus-bars.

5. Refer to the respective CLTI/CLXI Installation Guide for instructions on completing the installation and testing of the CLXI module.

Access Door Installation

After the terminal block and module have been installed and successfully tested, the access door must be installed on the CAENIB’s cover in the location of the terminal block.

1. If a blank plate is installed, remove it by removing the nuts that secure the plate to the CAENIB cover. Remove the plate from the mounting studs on the CAENIB cover.

2. Install the access door assembly as shown in the following diagram.

3. Replace the cover plate that was removed during the terminal block installation procedure described on the previous page.

4. If the module is being installed above or below another module within the enclosure, attach the supplied module interconnect cable between the two modules. The following illustration 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.
