4-3 Mounting Units
The Units that make up an NJ-series Controller 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 Controller.
1Join the Units so that the connectors fit exactly.
2The 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.
