Module Installation and

Removal

When installing the module in a chassis, it is not necessary to remove

the terminal block from the module. However, if the terminal block is

removed, use the write-on label located on the side of the terminal

block to identify the module location and type.

Terminal Block Removal

To remove the terminal block:

1. Loosen the two terminal block release screws.

2. Grasp the terminal block at the top and bottom and pull

outward and down.

ATTENTION

Remove power before removing or inserting this

module. When you remove or insert a module with

power applied, an electrical arc may occur. An

electrical arc can cause personal injury or property

damage by:

•

sending an erroneous signal to your system’s field

devices, causing unintended machine motion.

•

causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on

both the module and its mating connector. Worn

contacts may create electrical resistance.
