Installing an S7-200 Micro PLC
Installing an S7-200 Micro PLC onto a Standard Rail
Warning
!
Attempts to install or remove S7-200 modules or related equipment when they are
powered up could cause electric shock.
Failure to disable all power to the S7-200 modules and related equipment during
installation or removal procedures may result in death or serious personal injury, and/or
damage to equipment.
Always follow appropriate safety precautions and ensure that power to the S7-200
modules is disabled before installation.
To install the S7-200 CPU module, follow these steps:
1.
Secure the rail every 75 mm (3.0 in.) to the mounting panel.
2.
Snap open the clip (located on the bottom of the module) and hook the back of the
module onto the rail.
3.
Snap the clip closed, carefully checking to ensure that the clip has fastened the module
securely onto the rail.
Note
Modules in an environment with high vibration potential or modules that have been
installed in a vertical position may require DIN rail stops.
If you are installing an expansion module, use the following steps:
1.
Remove the bus expansion port cover from the existing module housing by inserting a
screwdriver into the space between the bus expansion port cover and the housing, and
gently prying. Ensure that the plastic connecting joints are completely removed. Use
caution not to damage the module. Figure 2-9 shows proper screwdriver placement.
2.
Insert the bus connector into the bus expansion port of the existing module and ensure
that the connector snaps into place.
3.
Ensure that the expansion module is correctly oriented with respect to the CPU module.
If you are using an expansion cable, orient the cable up towards the front of the module.
4.
Snap open the clip and hook the back of the expansion module onto the rail. Slide the
expansion module onto the bus connector until it snaps into place.
5.
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.
