Digital Expansion Terminal Block CompactBlock LDX I/O     5

Publication 1790-IN005C-EN-P - January 2015

Overview

This document describes how to install the expansion blocks.

Install Your Module

Follow these steps to install the block: 

 

1.

Mount the  block.

2.

Connect the expansion blocks.

3.

Wire the expansion blocks.

These steps are explained in detail in the following sections.

Mount the Expansion Block

Mount the expansion block by connecting it to a previously-installed 
CompactBlock LDX I/O base or expansion block.

Beginning with the base block, you can mount your expansion blocks either horizontally 
or vertically:

horizontally (left to right)

 – add expansion blocks in an end-to-end 

configuration

WARNING: 

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.
