Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on

component boards.

• Do not touch circuit components inside the equipment.

• If available, use a static-safe workstation.

• When not in use, store the equipment in

appropriate static-safe packaging.

ATTENTION

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.

This equipment is supplied as “open type” equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

NOTE: See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1 ("Industrial Automation Wiring and Grounding Guidelines"), for additional installation requirements pertaining to this equipment.

Installing CompactBlock LDX I/O

Follow these steps to install the base block:

1. Set the station address on the base block.

2. Mount the base block.

3. Mount the optional expansion blocks.

4. Wire the terminal blocks.

5. Connect the PROFIBUS connector.

6. Connect power to the block.

These steps are explained in detail in the following procedures.

Set the Station Address on the Base Block

To set the station address, adjust the switches on the front of the base block. The two switches are most significant digit (MSD) and least significant digit (LSD). The switches can be set between 00 and 99.

The base block reads the rotary switches at power-up only

Example: Station Address is set at 11

Publication 1790-IN009B-EN-P - April 2003

WARNING

Mount the Base Block

You can mount the base block to a panel or DIN rail. We recommend that you ground the panel or DIN rail before

mounting the base block.

When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with the proper wiring method that complies with the governing electrical codes.

Panel Mounting

1. Place the base block against the panel where you want

to mount it.

2. Gently pull and position the expansion cover to the left.

3. Place a center punch, nail or similar device through the

mounting holes in the base block and make two marks on the panel (lower left and upper right corners of the base block).

4. Remove the base block and drill two holes in the panel

to accommodate each of the mounting screws.
