Remove Power

System Assembly

The module can be attached to the controller or an adjacent I/O module before or
after mounting. For mounting instructions, see

"Panel Mounting" on page 7, or "DIN

Rail Mounting" on page 8. To work with a system that is already mounted, see
"Replacing a Single Module within a System" on page 8.

The following procedure shows you how to assemble the Compact I/O system.

1. Disconnect power.

2. Check that the bus lever of the module to be installed is in the unlocked

(fully right) position.

3. Use the upper and lower tongue-and-groove slots (1) to secure the modules

together (or to a controller).

4. Move the module back along the tongue-and-groove slots until the bus

connectors (2) line up with each other.

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.
