DIN rail. 2. Push the DIN rail latch back into the latched position. Use DIN rail end anchors (Allen-Bradley part number 1492-EAJ35 or 1492-EAHJ35) for vibration or shock environments.
Install Your Micro800 Expansion I/O Chapter 4 To remove your module from the DIN rail, pry the DIN rail latch downwards until it is in the unlatched position. Panel Mounting The preferred mounting method is to use two M4 (#8) per module. Hole spacing tolerance: ±0.4 mm (0.016 in.).
Chapter 4 Install Your Micro800 Expansion I/O Slide up both locks located at either side of each expansion I/O and then attach the I/O to the connecting latch hooks and bus connector on the controller or the last expansion I/O. After latching, slide down both locks to securely fasten the I/O to the controller.
