1. Secure the rail to the mounting panel every 75 mm (3.0 in.).
2. Snap open the clip (located on the bottom of the S7-200) and hook the back of
the S7-200 onto the rail.
3. Snap the clip closed, carefully checking to ensure that the clip has fastened
the S7-200 securely onto the rail.
To install the expansion module onto a standard rail, use the following steps:
1. Snap open the clip and hook the back of the expansion module onto the rail
next to the CPU or expansion module.
2. Snap the clip closed to secure the expansion module to the rail. Carefully
check to ensure that the clip has fastened the module securely onto the rail.
3. Plug the expansion module ribbon cable into the CPU connector under the
front access door. The cable is keyed for correct orientation.
