Installing Your Controller 2-13
Using a DIN Rail
The base unit and expansion I/O DIN rail latches lock in the open position so that
an entire system can be easily attached to or removed from the DIN rail. The
maximum extension of the latch is 15 mm (0.67 in.) in the open position. A
flat-blade screw driver is required for removal of the base unit. The base can be
mounted to EN50022-35x7.5 or EN50022-35x15 DIN rails. DIN rail mounting
dimensions are shown below.
To install your base unit on the DIN rail:
1. Mount your DIN rail. (Make sure that the placement of the base unit on the
DIN rail meets the recommended spacing requirements, see Controller
Spacing on page 2-11. Refer to the mounting template from the inside back
cover of the
MicroLogix 1500 Programmable Controller Base Units Installation
Instructions , publication 1764-5.1.
2. Hook the top slot over the DIN rail.
3. While pressing the base unit down against the top of the rail, snap the bottom
of the base unit into position. Ensure DIN latches are in the up (secured)
position.
4. Leave the protective debris strip attached until you are finished wiring the base
unit and any other devices.
