To mount the 1761-L32AAA onto a DIN rail, the manufacturer’s instructions say to first mount the DIN rail, allowing for the recommended amount of space for the device. Next, place the top slot of the controller over the DIN rail. Once this has been completed, snap the 1761-L32AAA into place while pressing it against the rail. The manufacturer recommends that you do not remove the controller’s protective wrapping until after the controller is properly mounted onto the DIN rail.VIIIVThe 1761-L32AAA is a MicroLogix 1000-Series Programmable Logic Controller by Allen-Bradley and Rockwell Automation.
