5-2 Installation

The Units that make up a CJ-series PLC can be connected simply by pressing the Units together and

locking the sliders by moving them toward the back of the Units. The End Cover is connected in the

same way to the Unit on the far right side of the PLC.

1. Join the Units so that the connectors fit exactly.

2. The yellow sliders at the top and bottom of each Unit lock the Units together. Move the sliders

toward the back of the Units as shown below until they click into place.

Precautions for Correct UsePrecautions for Correct Use

If the locking tabs are not secured properly, the connectors may become loose and not function

properly. Be sure to slide the locking tabs until they are securely in place.
